Stick it in your pool, or just above it, and this personal underwater clock counts the number of laps you swim, and records the time it takes to complete each lap, your total time and an estimate of calories burned (based on the weight you entered at set-up). Simply press the Lap Track to start, and again each time you complete a lap, and the Lap Track will do the rest. Each time the Lap Track is pressed, your split time will be shown in the LCD display for five seconds so you can check your times as you swim. The entire Lap Track is the "button", so you won't have to slow down to find and press any tiny buttons.
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.
