SpeedPuck sailing speedometer

£329.50

The award winning Speed Puck is completely self contained and can be installed in seconds, without tools. Instead of using a paddlewheel, the Speed Puck calculates your speed by measuring the Doppler shift in GPS signals to provide you with an updated reading twice a second. The Speed Puck never needs to be calibrated and maintains uniform accuracy at all speeds.
