Accurate speed over ground readings
Ideal for all speed applications
Useful for all types of watercraft
Includes 25' cable
The Sierra GPS Receiver with 25' cable is designed for use with Sierra GPS speedometers (not included). The GPS receiver is ideal for all speed applications and is particularly useful for craft where traditional speed sensors like pitot tubes and paddlewheels do not perform well. An added benefit is there is nothing in the water to corrode or break.
