GPS Speedometer

[David CVX-16]

Livorsi Marine makes GPS speedometers both in digital and analog in a varity of dash colors and rims, MPH indications from 80 to 200. The bad news is that the gauge with antenna/receiver, memory recall and harness runs $500 to $630 list. While this would be a necessity on fast tunnel and step hulls where the needle would bouce around and where accurate readings are essential, on our classic Glastrons, noncompetition driving, a simple handheld or dash mounted Garmin e-trex for $82 might be the practical solution.

Livorsi also has tournament speedometers reading from 0 -52 MPH.

But look at these Livorsi gauges reading 105 MPH at 7,500 RPM.

Only draw back to hand held GPS is trying to steer, work trim and check mph on gps.
The Livorsi GPS speedo would be worth more then my boat !

Looks like Bob has a Livorsi GPS speedometer and a bunch of money invested in his gauges.
