Velocitek – SpeedPuck
Instant installation with accuracy you can count on
If you race sailboats, the benefits of an accurate speedometer are probably already fairly obvious to you. Even still, you might not sail with a speedo because you can’t be bothered to drill holes in your hull and wire-up a paddlewheel transducer.
Or maybe you already have a through-hull speedo but you’re sick of the transducer getting fouled and you’re never quite sure if the instrument is properly calibrated.
The award winning SpeedPuck is completely self contained and can be installed in seconds, without tools. Instead of using a paddlewheel, the SpeedPuck calculates your speed by measuring the Doppler shift in GPS signals to provide you with an updated reading every half-second. The SpeedPuck never needs to be calibrated and maintains uniform accuracy at all speeds.
GPS speedometer for sailing and other applications. Big numbers, easy to install, accurate, waterproof. Includes speed, heading, maximum speed and automatic shift tracking.
