XL Series race clock race timer with sunlight readable LED digits

XL Series Raceclocks by Electro-Numerics set the standard for full-featured sports timers with all-solid state reliability and no moving parts. The display is provided by sunlight legible ultra-bright LEDs with a 90 wide viewing angle. The units can be ordered for single or dual-sided viewing, with 5 or 6 digits, and in three digit heights: 4", 6" or 9" (102, 152 or 229 mm). A rule of thumb is that viewing distance in feet is 40 times digit height in inches, or in metric terms, that viewing distance in meters is 0.5 times digit height in millimeters. Please see our Raceclock dimensions.

Internal sealed batteries provide 10 hours of continuous operation on a single battery charge. Intended for the North American market, XL Series Raceclocks feature an internal battery charger, a battery charge indicator, and a 120 Vac US power cord. The LEDs are driven by constant-current drive circuits to provide constant brightness for any level of battery charge.

The race clocks feature a rugged aluminum case with a carrying handle and a built-in keypad to select timing modes, time-of-day, and preset times. Remote operation is provided by an optional remote keypad, remote control unit, and remote display. Please see our Raceclock Accessories page. Options also include a tripod and a carrying case for each size Raceclock.


Other race clocks:  Intended for international markets, our CE-certified XLC Series Raceclocks feature an external 90-264 Vac, 50/60 Hz battery charger and a power cord for a specific country. Our LM Series Raceclocks feature yellow, reflective, electromagnetic flip digit in heights of 4", 6" or 9" (102, 152 or 229 mm). Also see our low-cost LED MileMarker Raceclocks, which are intended for use at mile marker locations along the race course.
