The SailTimer family of products are unique among GPSs in realizing that sailboats often tack to their destination, which affects the distance and travel time. If standard GPS chartplotters don’t know how far your tacking route is, how can they calculate the ETA correctly? Fortunately, SailTimer solves this problem.
Whether you use the SailTimer software in the app from iTunes or in The Sailing GPS, it provides an instant display of your optimal tacking route, distance and Tacking Time to Destination.
