Skywatch Speedwatch Wireless Speed Computer.  Ref:  MZ-17560

Measures speed through the water of any low-speed watercraft such as a sailboat, yacht, kayak or small powered boats. 

A small impeller, which requires no power source, is fitted under the craft, in a variety of mounting positions.  When the boat or kayak is moving through the water the impeller rotates creating a magnetic field received by an onboard transmitter.  The transmitter then sends a signal to the display. 

Speedwatch uses the speed data to display instant, average and maximum speed as well as trip and total distance.
