ELING Marine Auto MPH GPS Speedometer Odometer 80MPH Speed Gauge with ODO COG Trip 85mm for Car Boat Motorcycle 12 24 Volts

Installed on my boat. Extremely accurate. It is consistent with my chart plotter.

The other cheaply built one I bought failed within a few miles. Amazon service was fantastic. I chose this Eling because I liked the traditional look and simple, direct hookup. Wired it hot into my headlight switch on my 1951 IHC bus and hooked the backlight into the parklight lug on the switch. Ground to a screw under the dash. The pickup lead is like a mini coax cable that firmly threads to the speedo unit. Very simple for me to install as I just used a dryer vent sized hose clamp to secure it to my steering column. I like the way it's built. There are 2 buttons on the back for setting the color of light and the miles function. I have it set to trip and odometer. The trip gives your distance in miles and 10ths and odo rounded miles. I completely cut power to it by switching off my master cutoff switch and it still kept the trip and miles stored and they appeared when power was restored. Good! To reset the trip meter you press the button on the BACK of the speedo. Keep that in mind. This is well made and works well. Odo and speed are accurate. You could use this ruggedly built unit on just about anything. So far I've only gone exactly 9.3 miles as a test but I could not be more satisfied. This is the one you want for old hot rods or bikes or whatever. It seems tough and well sealed against moisture as well. I'm going to get another one soon for my Harley 72 XLCH.

I purchased this for an old motorcycle that was originally equipped with a Smith's "Chronometric" type. These older speedometers are effectively unobtainable (and never worked that reliably even back in the day) so I've been looking around for a replacement that was the right size and general appearance. I've been unsuccessful up to now -- cable driven units rarely have a cable and gear ratio that fits, electric ones require magnets on the wheel, there really wasn't anything out there. Then this turned up. Its the right size and the right shape for the machine and -- to my surprise -- it works reliably with a stable readout and no problems with lost GPS signal. I've only given it four stars because you have to improvise a mount (although an ABS pipe cap from the local hardware store does the job well its not perfect) and its geared to a negative earth system, leaving potential problems with shorting, but nothing that can't be overcome by someone who owns an old machine. The meter comes with an external antenna that's attached by a lot of thin coaxial cable, abut 12 feet (4 meters), so its easy to route the cable away from ignition systems and other potential interference sources. (I placed my antenna on the tail lamp mount where it always has a clear view of the sky).(PS -- One minor improvement would be to the LCD display. This shows things like trip and odometer but this being a GPS unit it should be able to optionally display latitude and longtitude.)

Very accurate speedometer. I replaced the cable driven one on my scooter because it was way off. This one is very accurate although sometimes it loses its satellite connection and does not work in some areas

Simple hook up for my sons cheep, I’m sure he’ll be excited, I know I am.

Here is the ELING Universal GPS Speedometer 160 mph w/ trip meter for my 1985 Honda V65 Magna. So, my original speedo recently quit on me & I was having trouble finding a new plastic gear that spins the cable to the gauge. But... I needed a speedo with a trip meter since the bike has no fuel gauge. I was able to reuse the original cup, but the ELING was a bit smaller than the original, so I wrapped electrical tape around it to take up the extra space. For the GPS speed sensor, I used double sided tape on the headlight mounting bracket- not pretty but it works for now. The wire to the sensor was way more than I needed, so I tied it up with small zip ties & tucked it underneath the gas tank. The only thing I wish is that the button to reset the trip meter was on the front of the gauge. Although it's possible to reach the buttons on the back through the hole where the speedo cable used to go, it's not very user-friendly. Overall, I'm pleased with my purchase.

I purchased this ELING GPS Speedometer for my fathers Kubota RTV 550 Utility Vehicle. My fathers RTV is garage kept and basically is used for him and my mother to take rides on the farm. When we first installed this GPS Speedometer it would take 10-15 for the GPS Antenna to find a signal once my father pulled the RTV out of the garage. 2 months ago the time increased from 10-15 seconds up to 2-3 minutes. This past week the time has increased up to over 5 minutes before the GPS Speedometer will find a signal now which allows the COG symbol to disappear.I contacted ELING through Amazon hoping to resolve this issue only to be told “I needed to give it more time” and the GPS Antenna could take 5 minutes before it finds a signal.I don’t ever remember seeing where it could take 5 minutes before this GPS Speedometer would function properly when I purchased this unit. Had I seen a statement like that I definitely wouldn’t have ordered this.I can’t imagine anymore purchasing a item which makes you set 5 minutes before it works properly. I didn’t order a hourglass I ordered a darned speedometer.Look Elsewhere
