The SpeedPuck is a reliable, easy to use instrument that gives you your important sailing performance parameters without any unnecessary clutter.

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. The SpeedPuck improves your sailing by allowing you to quantify the effects of boat trim, sail trim, wind shifts and current. No more second guessing yourself!

Do you hate reading manuals? We specifically designed the SpeedPuck so that almost anyone can figure out how it works in a few minutes without having to read anything.

Built to Last

The SpeedPuck is designed for long-term reliability in a saltwater marine environment. The SpeedPuck's case back screws on and off like the lid of a leak-proof water bottle to reveal the battery compartment. In addition to this, the battery compartment is completely sealed off from the rest of the device's electronics, providing a second layer of protection against moisture.
Fully Compatible with Velocitek PC Software

Two different PC software packages are available for the Speedpuck:

* Velocitek Control Center is free and works well for customizing the functionality of your SpeedPuck while providing basic data downloading and replay capability.
* Velocitek SpeedPlay ($49) is a more powerful tool that allows you to quickly download data from a group of Velocitek devices to create race replay animations with map backgrounds automatically imported from the Microsoft Virtual Earth server.
