Zero Off is a GPS speed control system, based solely on the input from satellites and the engine management system. It is based completely on the speed across the surface of the water; therefore, there is no requirement for skier weight, crew weight, KX, PX or even any kind of wind adjustment. You simply set the desired speed and go.

Looking for Software Rev S?
Software Rev S is an optional software upgrade for Zero Off head units using the new 3-Event GPS Antenna Puck (Click here to see the new puck on ZeroGPS.com). Rev S is sold separately and requires an ECOM reprogramming kit to program the unit. Rev S will not work with older Garmin GPS pucks.
