We are so excited to offer this clock that was designed and built in house at the O-Store. We incorporated all of the features that we, as race organizers and participants ourselves, would want to see in the ideal race clock. You'll find this clock is lightweight, easy to carry, and easy to set up. It can be easily programmed to show time counting up or counting down. And of course, your universally recognizable orienteering beeps. Beep beep beep beep beep BEEEEEP
