Re: tips for buying inboard ski boat?
The newest systems use GPS, however in moving water (i.e. rivers, currents, etc) GPS shows ground speed, not necessarily the speed of the water across the skis, so a paddlewheel speed sensor becomes more accurate. When combined with the in-course magnets, the times between Zero-Off and Perfect Pass are pretty darn close in most instances. They used manual methods until Perfect Pass came out, then the paddlewheel was the method, then GPS, etc. Point being, you won't be able to tell the difference between the two unless you ski the course a ton, and have Zero Off boats to compare against.
