The SC-1, recently used to win both the Moth Worlds and the Melges 24 North Americans, is for hard-core racers who are looking for an edge on the competition. Whether it is providing accurate VMG feedback to help you get the most out of your boat or helping you get a jump on the fleet with sag-busting distance to line measurements, the SC-1 gives you the instantaneous feedback you need to win.

When you buy an SC-1 it comes out of the box as an idiot-proof Compass and Speedometer. If you want more functionality, you can download and install our free Control Center Windows application. Control Center allows you to enable the SC-1’s advanced modes and download GPS data from your SC-1.

The SpeedPuck combines a high-accuracy GPS speedometer, compass and bar graph wind shift indicator in a compact, durable package. It is designed to be mounted on a dinghy or handheld when hiking on a sportboat.
