DESCRIPTION
DESCRIPTION
The Velocitek SpeedPuck is a self-contained GPS sailing speedometer and shift tracker — big, sunlight-readable speed you can read from anywhere in the cockpit, mounted on your mast in seconds without tools.
Instead of a paddlewheel, the SpeedPuck reads Doppler shift in GPS signals for a new, calibration-free speed twice a second — uniform accuracy at every speed, nothing to foul or recalibrate. The automatic shift tracker locks onto your mean heading for each tack and shows the knock or lift on a simple bar graph.
The 27 mm (1.1") high-contrast digits read across a 120° cone, so on boats under ~40 ft you can mount it on the mast and read it from the rail. It uses the same GPS technology as the ProStart used by America’s Cup World Series teams.

FEATURES
FEATURES
Speed mode:
- Displays speed and wind shift indicator updated twice a second. Can be disabled if prohibited by class rules.
Heading mode:
- Displays heading / course over ground and wind shift indicator, updated twice a second. Wind shift indicator can be disabled if prohibited by class rules.
Maximum speed mode:
- Displays maximum 10 second average speed, maximum instantaneous speed or flashes between both (user configurable).
Automatic shift tracking:
- The SpeedPuck's shift tracker locks on to the mean heading for your tack and then shows deviations from that heading with an easy-to-read bar graph. If you tack or jibe again, the shift tracker detects this, resets the bar graph and locks onto your new tack.
Waterproof:
- The SpeedPuck is designed for long-term reliability in a saltwater marine environment. The device's case back screws off like the lid of a leak-proof water bottle to reveal the battery compartment.The SpeedPuck's battery compartment is also sealed off from the rest of the device's electronics, providing a second layer of protection against moisture.
