We could not be happier with the EIGHT WiFi SwimNerd pace clocks at our new 50m facility! While each one can work independently doing so many things (count up, count down, stopwatch, program sets, time of day, and a pace clock), the magic of the connected wifi pace clock is that one pace clock can control all 8 of our pace clocks. All of the clocks are perfectly synced and can be controlled by the one "master" pace clock. The clocks "talk" to each other by using the same channel frequency (similar to the other brand with red lights) - it does not connect to your WiFi at your pool. The remote and app are easy to learn but if you have any questions, SwimNerd's personalized and quick customer service will walk you through any questions no matter how simple. The clock's enclosure is slim, sharp, simple to hang, and the green LED lights are unique and easy to read. Finally, the price of these clocks are unbeatable. Not only did we save thousands, but we were also happy to support a company that constantly gives back to the swimming community. Feel free to come check them out in person at the Mason Municipal Aquatic Center!
