Review on 🏍️ Universal 85mm Digital GPS Speedometer for Motorcycles, Cars, Trucks, Boats & Yachts - SAMDO SOG COG ODO Trip Meter by Zach Peterson

The GPS speedometer does everything I could hope for on my boat. It has a compass direction in degrees and an optional source indicator showing north, south, east, west. this will keep the up direction. However, the compass image isn't as useful as it could be. GPS acquires satellites very quickly (I drove it from ignition power). The speedometer stops working at around 2.5mph --> so it's not as useful as a trolling speedometer. This is the reason for the 4/5 rating. Otherwise I am satisfied with the purchase. I have driven over 300 miles since installing the sensor. Installation and durability are good.
