Geloo 85MM Boat GPS Speedometer Gauge 35 MPH 50 km/h Marine MPH Speedometer Waterproof Speedometer Odometer for Boat Truck Motorcycle Automotive Replacement Speedometers with 7 Colors Backlight 9-32V

The bezel and mounting ring have small flanges, will only fit narrow range of holes.

Very nice! Just took forever to receive.

Works as described.

I purchased this unit because of the design and the low speed range that was offered. It is installed in a diesel locomotive and is running on 32 VDC. Zero to 35 MPH is perfect for our application because our speed limit is 15 MPH. Most other brands only had ranges in the 0 to 80 MPH, 0 to 120 MPH or 0 - 160 MPH. I ran the receiver antenna up to the roof of the locomotive so no metal was in the way of the receiver. The unit indicates speed surprisingly well given the fact that a good portion of our railroad goes through a tree lined canopy. In open areas I expected the unit to indicate correctly and it did. Once we entered the tree area I expected the GPS signal to be interrupted and the unit to freeze up as the instructions say it will when the GPS signal is lost. It did no fail at all and the trees are very thick with branches and leaves. Maybe it will have more of a problem when the tree leaves are wet. This is only our second day of operation but so far, so good. On a bad note, unless you keep the unit powered up all of the time the reading on the odometer will zero out. On a good note, one of my engineers has trouble seeing a red back lit instrument and asked if the color could be changed to blue. I made the simple change and expected once powered down the unit would return to the default red back light. It returned to the blue back light when powered back up. If the unit continues to perform like is has these two days I will be very happy that I purchased it.Edit, after the second day of operation it appears only the trip odometer resets when power is removed. The odometer has retained the miles traveled from yesterday. My mistake.

Super easy to install and they are beautiful.

Works accurately, looks nice. Great price for a GPS speedometer

The mode and reset button is on the back.The speedometer is in the dashboard usable to access without removing the dashboard vary poor design

Used this for a conversion from a mechanical speedometer cable transmission to electrical signal. Instead of spending lots of money and doing lots of mathematical calculations I put this in the dash. Worked perfect, no complications and only three wires to install. What a great solution!
