Keep track of laps, split times and calories burned, all while you continually swim. Lap countdown feature allows you to set the amount of lap you wish to swim; Lap Track will then count down your laps until zero.
Lap Track attaches to the side of your pool using suction pads (two sizes included), or use the extending arm to hang the Lap Track in your pool if the wall surface isn't smooth. Carry case can also be filled with water to "weigh down" the extending arm. Two AAA batteries included.
