For shoppers seeking waterproof handheld stopwatches, my best overall pick is the FINIS Waterproof Stopwatch, which pairs swim-focused timing with 300 split memories and a stroke-rate mode. The Sper Scientific 810036A stands out for its 100-memory capacity and water- and shock-resistant build, while the TPNEG offers a three-row display for reading multiple timing figures at once. The main tradeoffs are how much lap data you need, how easy the display is to read, and whether water resistance is specified clearly enough for your swimming conditions. Simple timers can be easier to operate, while feature-rich models may better serve coaches tracking repeated splits. Read on for the full breakdown and help matching a stopwatch to your use.

Key Takeaways
- Swim-specific functions set the FINIS apart: Its 300 split memories and stroke-rate mode serve training tasks that basic timers do not cover.
- Memory capacity changes coaching usefulness: The FINIS stores more splits than the Sper Scientific 810036A, while the Sper pairs 100-memory timing with shock resistance.
- A larger display and a multi-row display solve different problems: The Accusplit Pro Survivor A601X emphasizes oversized digits; the TPNEG presents three rows of information.
- Waterproof claims vary across the lineup: Several products are explicitly labeled waterproof, while the United Scientific Supplies and Sper models are described as water-resistant.
- Some options trade stopwatch simplicity for broader value: The Beeasy combines watch and timer functions, and the Pgzsy and Sport Timer bundles provide two units for shared use.

More Details on Our Top Picks
Beeasy Men’s Digital Sports Watch, 50M Waterproof, 49mm Rubber Strap, Stopwatch, Countdown Timer, Alarm, Dual Time
For buyers who want a stopwatch they can wear between timing sessions, the Beeasy combines a 50-meter water-resistance rating with a stopwatch, countdown timer, alarm, and dual time. That makes it more versatile as an everyday sports watch than the dedicated FCXTU Digital Waterproof Stopwatch, which keeps its controls focused on basic timing. The enlarged display also helps with quick glances, while the 49mm case gives it a noticeably substantial wrist presence. Its stated rating suits swimming and outdoor use, but the guidance to avoid hot water and steam matters: water resistance does not mean it is suited to every wet environment. The tradeoff is a bulkier, less formal design, and the battery life is unspecified. Choose it for wearable versatility, not for lap-memory features or a compact handheld form.
Pros:- 50-meter water-resistance rating is suited to swimming and outdoor activities.
- Stopwatch, countdown timer, alarm, and dual time add uses beyond basic timing.
- Enlarged digital display is designed for quick reading.
- Shock-resistant and scratch-resistant construction supports active use.
Cons:- Large 49mm case may feel bulky, and the style is not aimed at formal wear.
- Hot water and steam should be avoided.
- Battery life is not specified.
Best for: Swimmers and outdoor athletes who want a wristwatch with a stopwatch plus countdown, alarm, and dual-time functions.
Not ideal for: Coaches who need a dedicated handheld timer with lap memory, or buyers who prefer a compact device and a clearly stated battery life.
- Water resistance:50M / 164Ft
- Display:Enlarged digital display with backlit EL
- Case material:ABS
- Strap material:PU
- Diameter:49mm
- Functions:Stopwatch, countdown timer, alarm, dual time, 12/24-hour format
Our verdict“Pick the Beeasy if you want a swim-capable sports watch with several timing functions, rather than a dedicated stopwatch.”
Accusplit Pro Survivor A601X Stopwatch with Extra Large Display
The Accusplit Pro Survivor A601X suits buyers who value a clear display and durable, uncomplicated timing over extra modes. Its water resistance is specified up to 30 meters, a useful advantage over the United Scientific Supplies Water-Resistant Stopwatch, whose resistance level is not stated. The large display and ergonomic “X” case are practical for coaches who need to read and hold the timer while keeping attention on an event. A stated five-year lithium battery life also gives this model a clearer maintenance picture than options with no battery-life information. Its limits are just as specific: timing is restricted to cumulative splits, with no lap timing, and button presses have no beep. The timing range tops out at 40 minutes, so it is less suitable for longer events than the Digital Stopwatch Timer for Sports, which lists a maximum time close to 100 hours.
Pros:- Water resistance is specified up to 30 meters.
- Extra-large display supports quick reading during sports.
- Five-year lithium battery life is stated.
- Ergonomic case and million-cycle switches are designed for repeated handling.
Cons:- Provides cumulative splits only, without lap timing.
- No beep signals button presses.
- Timing range is limited to 40 minutes.
Best for: Coaches and sports organizers who need a durable, easy-to-read timer for events within a 40-minute timing range.
Not ideal for: Swim coaches needing lap timing or memory, users timing long events, and anyone who relies on audible button feedback.
- Display:Extra-large digital
- Battery life:5 years
- Water resistance:Up to 30 meters
- Shock resistance:Yes
- Timing range:1/100 second to 40 minutes
- Switches:Million-cycle no-fail switches
- Operating system:WOS 2.5
Our verdict“Choose the A601X for straightforward, durable timing and a large display, but skip it if lap functions or longer timing capacity matter.”
FCXTU Digital Waterproof Stopwatch – Simple Swim Timer, Black
The FCXTU Digital Waterproof Stopwatch is the most focused swim-timing choice here: it is described as waterproof for surface swimming and limits operation to start/stop, reset, and on/off. That pared-back control set can be easier to manage poolside than the United Scientific Supplies Water-Resistant Stopwatch, which adds split and cumulative modes, a calendar, and an alarm. Its display shows minutes, seconds, and hundredths, while the included 47-inch lanyard lets a coach keep the timer close without holding it continuously. The product data specifies swimming use only, so I would not treat it as suitable for diving or deep-water timing. The tradeoff for its simplicity is the absence of lap memory, alarms, or other timing functions; its primary battery also needs replacement rather than recharging. It makes sense when basic pool timing matters more than versatility.
Pros:- Waterproof design is specified for swimming use.
- Simple start/stop, reset, and on/off controls reduce operating complexity.
- Display shows minutes, seconds, and 1/100th-second increments.
- Includes a 47-inch lanyard for hands-free carrying.
Cons:- Not specified for diving or deep underwater timing.
- No lap memory, alarm, or additional timing modes.
- Uses a non-rechargeable primary battery.
Best for: Swim instructors and poolside coaches who want a simple, lanyard-ready stopwatch for surface-swimming use.
Not ideal for: Divers, deep-water users, and coaches who need lap memory, split storage, alarms, or a rechargeable battery.
- Waterproof use:Swimming use only
- Display:Minutes, seconds, and 1/100th second
- Controls:Start/stop, reset, and on/off
- Lanyard length:47 inches
- Battery type:Primary, non-rechargeable
- Dimensions:3.15 × 2.4 × 0.83 inches
- Weight:57.8 g
- Resistance:Shock-resistant and dust-resistant
Our verdict“Choose the FCXTU for simple surface-swim timing with a lanyard, but look elsewhere for stored laps or deeper-water use.”
United Scientific Supplies Water-Resistant Stopwatch, Yellow
The United Scientific Supplies Water-Resistant Stopwatch earns its place for buyers who want both split and cumulative timing in a basic handheld unit. Those modes give it more flexibility for tracking separate intervals than the Accusplit Pro Survivor A601X, which is limited to cumulative splits. Hundredth-second increments support detailed timing, and the calendar/date display and alarm add everyday utility that the swim-focused FCXTU omits. The main uncertainty is central to this waterproof roundup: the product is described only as water-resistant, with no depth or immersion rating. I would treat it as suitable for incidental moisture rather than assume it can handle swimming. Its plastic construction keeps the design straightforward, but the available data does not establish greater durability or water protection. Choose it for timing modes and added display functions, not for confidently specified underwater use.
Pros:- Supports both split and cumulative timing.
- Measures in 1/100-second increments.
- Calendar/date display and alarm add functions beyond timing.
- Includes a lanyard for carrying or keeping the stopwatch close.
Cons:- Water-resistance level is not specified, so swimming suitability is unclear.
- Plastic construction offers no stated durability rating.
- Product data lists three settings without explaining their functions.
Best for: Coaches and school sports staff who need split and cumulative timing, plus a calendar and alarm, for damp or outdoor settings.
Not ideal for: Swimmers who need a stated swimming or immersion rating, and users who want documented water-resistance depth.
- Water resistance:Water-resistant; level not specified
- Timing modes:Split and cumulative
- Time resolution:1/100-second increments
- Display:Calendar/date display
- Alarm:Yes
- Material:Plastic
- Color:Yellow
- Included component:Stopwatch
Our verdict“Pick this model for split-and-cumulative timing in damp conditions, but choose a swim-specific option when immersion protection matters.”
Digital Stopwatch Timer for Sports, Green
The Digital Stopwatch Timer for Sports keeps the job narrow: it offers stopwatch timing, split and pause functions, and a large LCD, with a listed maximum time of 99 hours, 59 minutes, and 59 seconds. That long stated range sets it apart from the Accusplit Pro Survivor A601X, whose timing range ends at 40 minutes, while its single-mode design is simpler than the multi-function Beeasy watch. The quiet operation may suit classrooms, practice sessions, or users who do not want alarms and beeps. However, the supplied product data does not state any water-resistance rating, so despite its place in a waterproof-stopwatch roundup, I would not choose it for swimming or wet handling. Its plastic body is lightweight, but the buttons may make a shaking sound during operation, and battery life is unspecified.
Pros:- Listed maximum timing capacity is 99 hours, 59 minutes, and 59 seconds.
- Large LCD is designed for easy reading.
- Silent operation avoids beeps or alarms.
- Split and pause functions cover basic sports timing.
Cons:- No water-resistance rating is provided, so swimming use is not established.
- Stopwatch-only operation lacks countdown, clock, and alarm functions.
- Battery life is unspecified, and buttons may make a shaking sound.
Best for: Kids, beginners, and coaches who need a lightweight, silent stopwatch for long-duration timing in dry settings.
Not ideal for: Swimmers or outdoor users who need a stated water-resistance rating, and buyers seeking countdown, clock, or alarm functions.
- Mode:Stopwatch only
- Accuracy:1/100th second
- Maximum time:99 hours, 59 minutes, 59 seconds
- Display:Large LCD
- Timing functions:Split and pause
- Color:Green
- Material:Plastic
- Dimensions:0.6 × 2.3 × 2.9 inches
- Weight:1.6 ounces
Our verdict“Choose this timer for simple, quiet timing over long durations in dry conditions, not for waterproof swim use.”
Pgzsy 2-Pack Digital Sports Stopwatches with Large Screen
The two-stopwatch bundle makes sense for coaches, families, or training partners who want a timer in each person’s hand. Its large screen and one-touch controls favor quick checks over detailed race analysis, while stopwatch, clock, calendar, and alarm functions cover basic daily use. Compared with the Sper Scientific 810036A, it gives you a second unit but lacks stored lap data, countdown timing, and a pacer mode. The water protection is also described for splashes and rainy-day use, not immersion, so it is a weaker fit around pools than the FINIS waterproof model or the ACCUSPLIT’s stated 100-foot resistance. Lightweight plastic keeps the units easy to carry, but offers less reassurance against hard knocks than a more ruggedly specified build.
Pros:- Two stopwatches let a coach and athlete time the same session independently.
- Large display and one-touch controls support quick readings during practice.
- Clock, calendar, and alarm functions add everyday utility.
- Lightweight handheld design is easy to carry.
Cons:- Splash protection is not a claim of suitability for immersion.
- Plastic construction may be less reassuring around hard impacts.
- No lap-memory, countdown, or pacer function is listed.
Best for: Coaches, families, or training partners who need two simple handheld timers for outdoor practice and everyday splash exposure.
Not ideal for: Swim coaches and users who need immersion-rated protection, recorded split times, or advanced training modes.
- Pack size:2 stopwatches
- Material:Plastic
- Functions:Stopwatch, clock, calendar, alarm
- Timing precision:0.01 second
- Display:Large digital screen
- Water protection:Designed for everyday splashes and rainy-day use
Our verdict“Choose this pair for basic outdoor timing by two people, but pick the FINIS or ACCUSPLIT if water exposure is more demanding.”
Sper Scientific 810036A Water- and Shock-Resistant Stopwatch with 100 Memory
For coaches who need to review more than the finish time, the 100 split-and-lap memory is this stopwatch’s clearest advantage. Its three-line display shows elapsed, split, and lap readings together, reducing the need to cycle through information while timing an event. The countdown mode runs up to 20 hours, and the pacer can sound from 5 to 240 beats per minute, making it more training-focused than the simpler Pgzsy two-pack. Water- and shock-resistant ABS construction suits routine field use, but the listing does not state an immersion rating, so I would not treat it as a swim stopwatch like the FINIS. Its button-cell battery and unspecified water-resistance level are practical limitations for buyers who need clear battery details or dependable use in wet conditions.
Pros:- Stores up to 100 split and lap times for later review.
- Three-line display presents elapsed, split, and lap times together.
- Countdown and adjustable pacer modes support varied training sessions.
- Belt clip and lanyard provide carrying options.
Cons:- Water resistance is stated without a specific depth or immersion rating.
- Uses a button-cell battery, with no battery-life detail provided.
- More modes and stored data may be unnecessary for basic timing.
Best for: Track, fitness, and team coaches who want to save many split and lap readings and use countdown or pacing modes.
Not ideal for: Swim coaches who need a clearly specified waterproof timer, or buyers who want battery type and water-resistance details stated plainly.
- Model:810036A
- Memory:100 split and lap times
- Timing modes:Stopwatch, countdown, pacer, clock/calendar
- Countdown:Up to 20 hours
- Pacer range:5–240 beeps per minute
- Display:Three-line
- Materials and resistance:ABS plastic; water- and shock-resistant
- Included accessories:Belt clip, lanyard, button-cell battery
Our verdict“Pick the Sper Scientific for memory-rich coaching and pacing features, but not for swimming or clearly rated immersion protection.”
FINIS Waterproof Stopwatch for Swim Training – 300 Split Memory – Stroke Rate Mode – Easy-Read Display
The FINIS is the clearest choice for swimmers because it is explicitly described as waterproof and pairs that protection with swim-relevant timing tools. It stores 300 splits, supports dual-split comparison, and measures stroke and stride rates, giving coaches more useful training feedback than the general-purpose Marathon Adanac 3000. The large display and 1/100-second precision help with quick reads and close comparisons, while its timing range is capped at 10 hours. This focused feature set is a tradeoff: unlike the Sper Scientific, the supplied details do not list countdown or pacer modes, and there is no mention of an alarm or broader everyday functions. Buyers seeking one timer for many sports may find the ACCUSPLIT more adaptable, but for swim sessions the FINIS puts water suitability and performance analysis first.
Pros:- Waterproof design is suited to swimming use.
- Stores up to 300 splits for reviewing training intervals.
- Dual-split memory supports comparisons between times.
- Stroke and stride rate functions add sport-specific feedback.
Cons:- The 10-hour timing limit is shorter than the ACCUSPLIT’s 24-hour range.
- The supplied details do not list countdown, alarm, or clock functions.
- Its swim-focused tools may be unnecessary for general sports timing.
Best for: Swim coaches and swimmers who need waterproof timing, substantial split storage, and stroke-rate information for training.
Not ideal for: Buyers who want a general-purpose stopwatch with listed alarms, countdown functions, or a timing range longer than 10 hours.
- Waterproof:Yes
- Memory:300 splits
- Display:Large digital
- Timing range:Up to 10 hours
- Measurement precision:1/100 second
- Timing features:Dual-split memory; stroke and stride rate measurement
Our verdict“Choose the FINIS for poolside or swim-training use when waterproofing and split analysis matter more than broad everyday functions.”
Marathon Adanac 3000 Digital Stopwatch, Neon Green
The Marathon Adanac 3000 suits field timing where dust, bumps, and rain may all be part of the day. Its water-, dust-, and shock-resistant design gives it broader stated environmental protection than the Pgzsy pair, whose splash-focused description is more limited. A large display, soft-grip buttons, and a 46-inch lanyard make it practical to hold or wear while moving between athletes. It also includes time-out and split modes plus clock, calendar, and alarm functions, though it does not offer the extensive stored split capacity of the Sper Scientific or FINIS. The plastic case may not feel as robust as metal, and no battery type or life is specified. Its water resistance is useful, but no immersion depth is provided, so it is not the safer pick for swimming.
Pros:- Water-, dust-, and shock-resistant construction suits varied outdoor conditions.
- Large display and soft-grip buttons aid handling and readability.
- Time-out, split, and time/calendar functions cover common timing needs.
- Includes a 46-inch lanyard for carrying.
Cons:- Water resistance is not given as an immersion depth.
- Plastic construction may be less robust than metal alternatives.
- Battery type and battery life are not specified.
Best for: Outdoor coaches and officials who need a lanyard-equipped timer with water, dust, and shock resistance for field conditions.
Not ideal for: Swimmers who need a clearly immersion-rated stopwatch, or data-focused coaches who want extensive split memory.
- Model:ST083000
- Color:Neon green
- Material:Plastic
- Timing precision:1/100 second
- Modes and functions:Time-out, split, clock, date, day, alarm
- Resistance:Water-, dust-, and shock-resistant
- Dimensions:0.5 × 2.25 × 2.75 inches
- Weight:68.04 g
- Included accessory:46-inch lanyard
Our verdict“Choose the Marathon for general field use in wet or dusty conditions, but choose the FINIS for swimming or the Sper Scientific for extensive split storage.”
ACCUSPLIT Pro Survivor A601X Stopwatch with Clock and Extra-Large Display
Among these five, the ACCUSPLIT A601X has the clearest stated water-resistance depth: up to 100 feet (30 meters). That makes it a stronger choice for demanding wet conditions than the Marathon Adanac 3000, which is described as water resistant without a depth, and a more convincing fit near water than the Pgzsy splash-resistant pair. Its extra-large display, shock-resistant case, and cumulative split, split/release, and one-two fast-finish functions keep the controls focused on straightforward sports timing. The CR2032 lithium battery is expected to last five years, though the buttons have no beep feedback. There is also no lap timing, and its cumulative-split approach is less suited to the extensive stored results offered by the Sper Scientific. I’d favor it for durability and readability over complex data review.
Pros:- Water resistance is specified up to 100 feet (30 meters).
- Extra-large display supports quick reading during active timing.
- Shock-resistant case and million-cycle switches are built for repeated use.
- CR2032 lithium battery has an expected five-year life.
Cons:- Timing supports cumulative splits but does not include lap timing.
- Buttons provide no beep feedback.
- Offers less stored-data and training-mode detail than the Sper Scientific or FINIS.
Best for: Officials and coaches who need a readable, shock-resistant timer with a clearly stated water-resistance depth for wet environments.
Not ideal for: Coaches who need lap timing, stored split histories, audible button feedback, or specialized swim-training measurements.
- Model:A601X
- Timing functions:Cumulative splits, split/release, one-two fast finish
- Timing range:Up to 24 hours
- Timing resolution:1/100 second to 40 minutes
- Display:Extra-large digital display
- Clock functions:12/24-hour time, month, date
- Water and shock resistance:Water-resistant up to 100 feet (30 meters); shock-resistant
- Battery:CR2032 lithium; expected life 5 years
- Case and buttons:Ergonomic X case; million-cycle switches; no beep
Our verdict“Choose the ACCUSPLIT for a large display and clearly stated water resistance, but select the FINIS for swim analysis or the Sper Scientific for extensive split memory.”
TPNEG Waterproof Digital Stopwatch with 3-Row Display
The TPNEG is the strongest fit here for coaches or athletes who want more than a running clock without moving to a specialized lap counter. Its IPX7 water resistance is specified for immersion up to 1 meter for 30 minutes, while the three-row display and storage for 10 data sets make it easier to review fastest, slowest, and average times during a session. Compared with the MUSHPORT, it adds countdown, clock, alarm, and metronome functions, but its maximum timing span is much shorter. The Sportcount is the more focused choice for tracking many laps in deep-water use; the TPNEG is better for mixed training tasks and recorded results. Its tradeoffs are a non-rechargeable CR2032 and alerts that still sound in silent mode.
Pros:- IPX7 rating is specified for immersion in up to 1 meter of water for 30 minutes.
- Stores 10 data sets and reports fastest, slowest, and average times.
- Three-row display presents timing information at a glance.
- Includes countdown, clock, alarm, and metronome modes alongside the stopwatch.
Cons:- Maximum timing is 10 hours, far shorter than the MUSHPORT’s stated 99-hour, 59-minute, 59-second span.
- Uses a non-rechargeable CR2032 battery.
- Silent mode does not mute countdown, alarm, or metronome alerts.
Best for: Coaches and individual athletes who train in wet conditions and want stored session results plus several timing modes.
Not ideal for: Swimmers who need deep-water lap tracking or users who want silent countdown and metronome alerts.
- Water resistance:IPX7; withstands immersion in 1 meter of water for 30 minutes
- Timing accuracy:0.01 seconds
- Maximum timing:10 hours
- Memory:10 data sets; fastest, slowest, and average times
- Functions:Stopwatch, countdown timer, clock, alarm, metronome
- Display:Three-row
- Battery:Replaceable CR2032, non-rechargeable; stated life up to 2 years under normal use
- Dimensions and weight:2.56 × 0.98 × 3.35 inches; 0.07 kg
- Lanyard:47 inches
Our verdict“Choose the TPNEG for wet training that benefits from saved results and multiple modes, but pick the Sportcount for deep-water lap counting.”
MUSHPORT Waterproof Digital Stopwatch with ON/OFF, Blue
The MUSHPORT suits buyers who need a straightforward stopwatch that can keep timing well beyond a typical practice. Its display runs to 99 hours, 59 minutes, and 59 seconds, and split timing lets a user record an interval while the overall clock continues. That makes it a more focused long-session tool than the TPNEG, which offers more modes and saved data but tops out at 10 hours. The MUSHPORT is listed as waterproof and designed for swimming, though its product details do not give a depth or immersion rating; the Sportcount’s stated 50-meter resistance is a clearer choice for serious underwater use. This model stays simple by design: no clock, countdown, or audible alerts. Its silent operation can be useful at meets, but there is no alert if a user needs one.
Pros:- Split timing records intervals while total elapsed time continues.
- Timing range extends to 99 hours, 59 minutes, and 59 seconds.
- Large LCD and 1/100-second accuracy support clear, fine-grained timing.
- Silent operation and a long-press ON/OFF switch keep operation simple.
Cons:- Waterproof status is stated without a specific depth or immersion rating, unlike the Sportcount’s 50-meter specification.
- Stopwatch-only operation omits a clock, calendar, and countdown timer.
- No audible alerts are available for users who rely on sound cues.
Best for: Swimmers and coaches who want a silent, split-timing stopwatch for extended sessions and do not need extra timer modes.
Not ideal for: Divers or swimmers who need a published water-depth rating, and users who need countdowns, clock functions, or audible alerts.
- Waterproofing:Listed as waterproof; no depth rating provided
- Timing accuracy:1/100 second
- Maximum timing:99 hours, 59 minutes, 59 seconds
- Functions:Stopwatch with split timing; ON/OFF switch
- Display:Large LCD
- Sound:Silent; no beep, alarm, bell, or whistle
- Dimensions and weight:0.6 × 2.5 × 3.3 inches; 0.06 kg
- Included:Battery, lanyard neck strap, user manual
- Warranty:1 year
Our verdict“Pick the MUSHPORT for quiet split timing over long sessions, but choose the Sportcount if a stated underwater depth rating matters most.”
Sportcount Waterproof Lap Counter and Timer
The Sportcount takes a different approach from the handheld stopwatches in this group: it is designed to track laps with a finger-operated counter rather than offer a broad menu of timing modes. Its 50-meter water resistance is the clearest stated underwater specification among these four picks, and the capacity for up to 999 laps makes it suited to long swim sets where keeping count can be as challenging as measuring time. Compared with the MUSHPORT, it emphasizes lap tracking and a shot timer instead of long-duration stopwatch timing and split functions. The compact, single-finger operation can leave a swimmer focused on movement, but buyers who need a large, glanceable display, stored results, or countdown and clock functions should choose a conventional model such as the TPNEG. Its feature set is purpose-built, not versatile.
Pros:- 50-meter water resistance is the strongest stated depth rating among these four products.
- Counts up to 999 laps, supporting long training sets.
- One-finger operation can make lap tracking easier during active workouts.
- Designed for swimming, running, cycling, and other lap-counting tasks.
Cons:- Its counting-focused design does not provide the TPNEG’s broad set of timer modes and stored data.
- Product details do not specify timing accuracy or maximum elapsed timing.
- Plastic or rubber construction may feel less substantial to buyers seeking a more premium finish.
Best for: Swimmers who need to count lengthy sets underwater with a finger-operated device and a stated 50-meter water-resistance rating.
Not ideal for: Coaches who need a large handheld display, stored split data, or general-purpose timing modes.
- Water resistance:50 meters
- Maximum lap count:999
- Settings:5
- Operation:One-finger lap counting and timing
- Additional timing feature:Shot timer
- Material:Plastic or rubber
- Color:Blue
- Weight:13.61 g
Our verdict“Choose the Sportcount for underwater lap counting and a defined depth rating, not as a replacement for a feature-rich handheld stopwatch.”
Stopwatch Sport Timer, 2 Pack Large Display Digital Stopwatch with Date and Time, Silent, Easy to Use for Sports, Coaches, Kids, Swimming, Running
This two-pack is the practical pick when a coach, parent, or training partner needs a stopwatch in each hand without a complicated setup. The large LCD, bright yellow cases, and three-button layout make the basic timing functions approachable, while silent operation avoids button beeps during practice. Compared with the MUSHPORT, this set adds date and time display and supplies two units, but the MUSHPORT has a stated split-timing function and a much longer timing range. The waterproof claim is also less specific here: the product data describes the plastic as water-resistant but gives no immersion or depth rating, so I would not choose it for regular underwater use ahead of the Sportcount or the IPX7-rated TPNEG. It keeps to basic time and date functions, with no countdown, alarms, or lap memory.
Pros:- Includes two stopwatches, useful when timing two participants or keeping a spare available.
- Large LCD and bright yellow color make the units easy to locate and read.
- Silent operation avoids audible button sounds during practice.
- Simple three-button layout reduces the learning curve for children and new users.
Cons:- Only described as water-resistant, with no immersion or depth rating supplied.
- Lacks lap memory and countdown functions available on more capable options such as the TPNEG.
- Product details do not specify a maximum timing range or battery type.
Best for: Parents, teachers, and coaches who want two simple, easy-to-read timers for dry or lightly wet practice settings.
Not ideal for: Swimmers who need a defined underwater rating, or coaches who need lap memory, countdowns, or advanced timing features.

Our verdict“Choose this set for two uncomplicated, readable timers, but select the TPNEG or Sportcount for more clearly specified water protection.”
How We Picked
I compared the 14 listed products against the needs that make waterproof handheld timing different from ordinary stopwatch use: water exposure, lap tracking, display readability, handling, and the ability to operate the timer quickly. I gave weight to clearly stated functions such as split-memory capacity, stroke-rate mode, multi-row displays, and shock resistance. I also separated explicitly waterproof models from products described as water-resistant, since those labels do not establish the same level of protection.
The order favors options with a strong match between their stated features and a clear buyer need, not the longest feature list. The FINIS leads for swim training; the Sper Scientific and Accusplit offer distinct alternatives for memory and display priorities. More basic timers, multi-packs, and wristwatch-style options rank lower for buyers who need a dedicated handheld stopwatch, though they can make more sense for simple timing or shared use. Product names alone do not establish an immersion rating, so buyers should confirm manufacturer guidance for their intended water exposure.
Factors to Consider When Choosing Handheld Stopwatches Waterproof
Choosing a stopwatch for wet conditions involves more than finding the word waterproof on a product page. Match the protection claim, controls, and timing functions to where and how you plan to use it; a pool-deck coach and a runner timing short intervals have different priorities.
Match Water Protection to the Actual Activity
Water exposure can mean splashes at a pool, rain during practice, or repeated immersion, and those are not interchangeable conditions. Check the manufacturer’s stated water-resistance or waterproof rating and read whether it applies to immersion, depth, and duration. Do not infer swimming suitability from a product title or a general water-resistant label. A model intended for poolside timing may not be appropriate to take into the water. If the listing gives no specific rating, contact the manufacturer or choose a model with clearer guidance. Also check whether the buttons can be pressed underwater, since water protection alone does not confirm that operation is supported.
Decide How Much Split Memory You Will Use
Split memory matters when you need to capture multiple laps without stopping to write each time down. A large memory count can help a coach review a long set, but it adds little for someone timing one sprint or a single race. Think through how many athletes or intervals you record in one session and whether you need to recall results on the device afterward. A stopwatch that stores data is not automatically a replacement for a logbook or timing system. Check how splits are displayed and retrieved, not just the advertised capacity. If the memory workflow is awkward, a simpler timer paired with written records may be more practical.
Choose a Display for Your Viewing Distance
Display design affects whether a reading is useful at the moment you need it. Extra-large digits can be easier to read at arm’s length or during fast-moving practice, while a multi-row display can show several timing values together. Those benefits differ: bigger numbers do not necessarily show more information, and extra rows may appear crowded to some users. Consider glare, indoor versus outdoor use, and whether you will hold the stopwatch or keep it on a lanyard. If several people need to read a result, prioritize legibility over extra modes. Check the display layout in product images or documentation before choosing.
Keep Controls Simple Enough for Wet Hands
Timing often requires quick starts, stops, and split captures, so button placement and labeling matter as much as the feature list. Small or closely spaced buttons can be difficult to use with wet fingers, even if the case itself is water-resistant. Extra functions such as clocks, alarms, and countdown timers can be useful, but they may add steps to basic operation. For coaching or school use, favor controls that make the start-and-split sequence easy to learn and repeat. If multiple users will share the stopwatch, a short practice session before an event can prevent missed timing. Check whether the device’s instructions explain how to lock, reset, or clear stored results.
Pay for Features That Fit Your Timing Routine
A higher-feature model makes sense when its memory, stroke-rate mode, or durability addresses a recurring need. For casual use, those extras can mean more controls to manage without improving the timing task. Multi-packs may be a better fit when two coaches or lanes need separate timers, but confirm whether both units offer the functions and protection you need. Wristwatch-style products add everyday timekeeping, though they are not always as convenient to operate as a dedicated handheld unit. Compare the specific features rather than assuming a longer list means better value. The right choice is the least complicated model that still covers your activity and water exposure.
Check Battery and Care Requirements Before Buying
Wet-use equipment needs simple care habits to stay reliable. Read the instructions for rinsing, drying, battery replacement, and storage, especially after exposure to chlorinated or salt water. A water-resistant case can lose protection if its seals are damaged or the battery cover is not fitted correctly. Check whether the battery is replaceable and whether replacement instructions preserve the water seal. Avoid pressing buttons or opening the case in wet conditions unless the manufacturer permits it. These small maintenance details can matter more over time than an added timing mode.
Frequently Asked Questions
Can I use any stopwatch labeled waterproof while swimming?
No. The word waterproof in a product name does not tell you the depth or duration of immersion the device can handle. Look for a specific rating and guidance from the manufacturer about swimming use. Also check whether button operation is allowed underwater, since some devices may be protected against water but not designed for button presses while submerged. If the product only says water-resistant, treat it as a more limited claim until the manufacturer clarifies its intended use.
Is a high split-memory count worth it for a swim coach?
It can be useful if you regularly record many laps or want to review splits after a set without stopping to write them down. The FINIS lists 300 split memories and a stroke-rate mode, while the Sper Scientific lists 100 memories, so the difference may matter during longer sessions. For short practices or one-off race timing, fewer stored splits may be enough. Check how easily the stopwatch recalls and distinguishes stored times, since memory capacity is only helpful if the results are practical to retrieve.
Should I choose a large display or a three-row display?
Choose based on what you need to read quickly. An extra-large display, like the one emphasized by the Accusplit Pro Survivor A601X, favors reading prominent timing figures at a glance. A three-row layout, like the TPNEG’s, may show more timing information together, which can help when tracking several values. More rows can also make the screen feel busier, while large digits may show less at once. If possible, check the screen layout against your typical viewing distance and timing routine.
Is water-resistant good enough for poolside timing?
It may be, if the stopwatch will face only occasional splashes and the manufacturer describes that use as suitable. Poolside exposure can still include wet hands, spray, and accidental drops into water, so a vague label leaves some uncertainty. The United Scientific Supplies and Sper Scientific models are described as water-resistant, while other products in this lineup are marketed as waterproof. Those descriptions alone do not establish equal protection. For repeated splash exposure or any chance of immersion, seek a specific rating and follow the maker’s care instructions.
When does a two-pack make more sense than a single premium stopwatch?
A two-pack is practical when two people need independent timers, such as coaches working with separate groups or families timing different activities. The Pgzsy and Sport Timer options provide two units, which can reduce sharing and handoff delays. A single feature-rich stopwatch may be a better fit if one person needs extensive split memory, a specialized swim mode, or clearer display controls. Compare each unit’s stated water protection and functions rather than assuming both timers in a bundle meet your needs. For organized training, it can also help to choose matching units so users follow the same controls.
Conclusion
My best overall pick is the FINIS for swim training, thanks to its 300 split memories and stroke-rate mode. The Sper Scientific 810036A is my best premium-style choice for durability and stored splits, while the Accusplit Pro Survivor A601X makes sense for buyers who put a large display first. For simple timing or shared use, the Pgzsy and Sport Timer two-packs are the value-oriented options; beginners may prefer a basic timer with fewer modes to learn. Choose Beeasy if you also want watch and countdown functions, and Sportcount if its lap-counter format fits your routine. Before buying any model for swimming, verify the manufacturer’s water-protection guidance for your planned use.
