Samdo Universal 85mm GPS Speedometer Odometer 80MPH With Backlight 12V/24V For Marine Boat

Ordered this gauge because it had next day delivery and an odometer. I wanted to replace a non-working speedometer in my boat in time to do some speed testing in two days while the weather was still fairly warm. The description said it had an odometer. I didn't take time to read the reviews because I needed to place my order quickly. Therefore I got a speedometer with COG meter instead of a distance meter. I accept most of the blame for not being more careful. Otherwise it is a nice gauge.If you want a speedometer with an odometer, check out this: https://www.amazon.com/ELING-Motorcycle-Speedometer-Different-Backlight/dp/B07DY3MBJL/ref=sr_1_6?dchild=1&keywords=GPS+speedometer+with+odometer&qid=1605745238&sr=8-6I think I will order one for next year.

it seems very steady and fairly accurate. It was kind of a pain to install, the instructions are clear, but it would be nice if it had electrical connection posts instead of just wires. Overall it is very nice ... aside from the red backlight not really matching my other displays.

very easy to install. very accurate. great investment

Great product. Worked and functioned as advertised except that only the front is waterproof. Mine got water inside from the rear conections. Great customer service! They replaced it promptly no problems. Plan to seal the conections this time and expect it to work for a long time.

I haven’t installed the product yet but confident it will satisfy my need
