Tenet Waterproof Nautical Marine Analogue GPS Speedometer In MPH

Marine GPS speedometer

The unit has a classic needle speedo that shows MPH up to 125
 
We also have a digital version of marine GPS that has a compass & higher MPH/KPH/Knot display and a unit with KPH up to 125 and MPH up to 75 on the same unit

 
This is primarily a marine unit designed for boats and ships but could be used for a quadbike, tractor or similar outdoor use as the unit is fully waterproof to IP67
 
Simple to fit requiring 2 x positive feeds (One to power the unit & one for the backlight) and 1x negative feed (12 & 24V compatible)

Working temperature -40 to 85 degrees celcius

We also have a mounting bracket if you want to mount onto something like a handlebar or panel instead of fitting into a dash

The back light can be changed between off, red and yellow

Installation steps/Features:

1. Cut an 85mm (3 3/8") hole in the panel and allow for 55mm (2 3/16") of clearance behind the panel

2. Remove the fastening ring and insert the gauge from the front, you can then keep the unit in place by replacing and tightening the fastening ring from the back

3. Insert the wire harness firmly into the gauge

4. Connect the cables according to the diagram (included in the box with the unit). You can now choose either red or yellow as the backlight (you can leave the back light off although this may make it difficult to see in bright light). The unit will work with 12V or 24V DC, when installing to a 24V circuit it is essential that the 100ohm resistor supplied is placed in series to the positive supply to both red and orange/yellow wire. Failure to do so will result in damage to the unit and will not be covered under our returns policy

5. Securely fasten the GPS antenna, preferably outside so that it has a clear view of the sky, and connect the antenna cable to the socket in the back of the gauge. DO NOT CUT THE CABLE

6. After turning the power on allow the gauge to sample the satellite signal for 1 minute. The needle on the gauge indicates the SOG (Speed Over Ground) when vehicle is moving. When the vehicle is stationary the LCD screen displays the accumulative kilometres travelled and is stored in the unit even when the unit is powered off. While vehicle is not moving all the data is frozen, so the compass cannot be used as a reference until the boat begins to move again and the signal is recovered

7. All data is for reference only and should not be trusted as the sole navigation source
