How We Picked
Our selection process focused on large LED displays that are easy to see from across the pool, with features tailored for swimming training. We prioritized models that offer high visibility, flexible timing options, and durability for outdoor or poolside environments.

Factors to Consider When Choosing Large Led Pace Clock For Swimming
Selecting the right large LED pace clock for swimming depends on your training environment, needs for features, and budget. Consider where you’ll use it most—outdoors or indoors—and whether you prefer manual controls, remote operation, or app customization. Size and visibility are crucial, but so is the clock’s flexibility in timing modes. Here are some key points to guide your choice:
Size and Visibility
Large LED displays are essential for clear visibility from across the pool. The 15-inch models like the Accusplit AX850 excel in lane timing, while the 9-inch clocks are better suited for outdoor settings where sunlight can impair smaller displays. Make sure the clock’s size matches your pool’s dimensions and your training layout.
Features and Functionality
Consider whether you need multiple timing modes such as count up, countdown, or interval timing. The ULTRAK T-120 offers the most versatility with remote control and multiple modes, making it ideal for varied training routines. The Pace Clock for Swimming is more focused on outdoor use with app connectivity, while the Accusplit AX850 is straightforward for basic timing.
Power and Portability
Some clocks require AC power, limiting placement flexibility, while others like the ULTRAK T-120 provide rechargeable batteries for poolside portability. Outdoor models like the Pace Clock for Swimming are water-resistant but may lack long-lasting battery details, so check your environment’s power sources before purchasing.
Ease of Use and Control
Manual controls like push buttons keep things simple, but remote controls or app-based programming add convenience, especially during coaching. Think about how you prefer to operate the clock during training sessions, and choose accordingly.
Frequently Asked Questions
What size LED display is best for swimming pace clocks?
For swimming, especially across multiple lanes or outdoor pools, larger displays like 15 inches provide better visibility from a distance. Smaller clocks, such as 9 inches, may be suitable for outdoor settings where sunlight can make smaller displays harder to see, but they might not be ideal for lane timing.
Should I choose a Bluetooth-connected clock or one with remote control?
Bluetooth-connected clocks like the Pace Clock for Swimming are excellent for outdoor pools and app customization but rely on an app and connectivity. Remote-controlled clocks like the ULTRAK T-120 give quick manual operation and are more straightforward for poolside use, especially when app connectivity isn’t desirable.
Are rechargeable batteries necessary for a pace clock?
Rechargeable batteries offer flexibility for portable use, especially for timers like the ULTRAK T-120. If your training setting involves frequent movement or multiple locations, a clock with rechargeable power can be more practical. However, always check battery life and charging requirements to ensure it suits your schedule.
Can these clocks be used outdoors?
Yes, the Pace Clock for Swimming is specifically designed for outdoor environments with waterproof electronics and high visibility. The ULTRAK T-120 is portable and can be used outdoors if powered properly. The Accusplit AX850 is mainly suited for indoor or lane-specific timing, as it lacks water resistance and outdoor features.
What training scenarios are best suited for each clock?
The Pace Clock for Swimming is best for outdoor, large-area timing with app customization. The ULTRAK T-120 is versatile for team training, interval work, and poolside use with remote control. The Accusplit AX850 is ideal for basic lane timing and beginner training, where simplicity and visibility are priorities.
Conclusion
If you’re an outdoor coach or swimmer needing a highly visible, customizable clock, the Pace Clock for Swimming is the best choice. For team training and versatile timing needs with remote operation, the ULTRAK T-120 offers excellent flexibility. Beginners or those who prefer simplicity should consider the Accusplit AX850 for a large, easy-to-read display that gets the job done without extra features.
