More than just a speed log, ST60+ Speed calculates a wealth of speed related information including current speed, maximum speed, average speed, velocity made good (VMG) and speed over ground. ST60+ speed also keeps track of distances traveled with its boat log and resetable trip distance displays. The ST60+ Speed instrument also displays water temperature in degrees fahrenheit or celsius. The ST60+ Speed instruments' timer capabilities include a count-up timer and two race-start timers.
