85MM Speedometer Gauge

I replaced all the gauges and switches in my sons 1992 Glastron Carlson CSS 16. They all look great, the Speedo is GPS, so no pickup tube on the back of the boat to clog with weeds, it also has a resettable trip odometer and a Non resecting odometer along with different colors for the background light. The Tachometer includes an hour meter.A very nice-looking upgrade to a 32-year-old boat.

Easy set up and use. Seems to be working perfectly fine for me. Only thing is wish you could change the dial color from the face of the dial rather than the back of the unit. In my case once it's installed I can't change the colors, so I set it on the one I wanted before install so no big deal really.

Standard install no issues, checked accuracy with other gps instruments was dead on. Worked great! Like the different color led backlights. For the money it's a good deal and good product. I say yes get one.

Very nice gage. Great function and looks great on my boat.

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.

Works good even with the funky instructions. Picks up satellites fast and was a direct replacement install. Not real big on features, but it would have been nice if the trip odometer reset was not a button on the back of the unit. Sorta hard to reach under the dash and find it when needed.

Installed in my boat last year...no more cleaning out the intake a few times a year. Installed in minutes and works great.

Super easy to install. I used Google maps to verify accuracy and it's pretty accurate. It's usually 1-2 mph above or below (assume it's just a delay with GPS signal)
