The Z-100 Stopwatch is packed with advanced timing options for performance monitoring. Showcasing a 100-dual split automatic memory and timing capability to 1/100th of second, the LSW Stopwatch accurately tracks performance in detail. With display options for day, date and calendar, the Z-100 Stopwatch allows for varied entry/exit timing configurations and features a stroke frequency counter so you can gauge the performance of your swimmers. A rapid memory review (with auto stop at last display) allows for easy retrieval of data, while water and shock resistant construction allows for long lasting use. Ideal for training days and race days, an adjustable neck lanyard with TYR logo keeps the Z-100 stopwatch at your fingertips and ready for action.
