Sport Systems chip time road races but old fashioned stopwatches are still a prerequisite. Periodically we stock up on watches to make sure we have a couple at each event. Thanks to Fastime for supplying.
Good for open water swimming / snorkelling. May be ok for surfing too but still to try out. Large digits are useful when I''m not wearing glasses. Would be useful in swimming pool too, but may get snagged in lane ropes because of size.
