After looking for an inclinometer for a year or so, and not finding an electronic one, I was about to build one out of the guts of a couple of digital levels.
Then I found out those levels cost over $100 each.
The vehicle inclinometers available in the US had two fatal flaws. Most of them had little JEEP pictures in the middle, not generic vehicles. Like this was ever going to be allowed on MY dashboard:
Rare ones made for Land Rovers and so forth also had identifiable silhouettes. The other problem was they were all floating levels, very low-tech. Not up to Roadie dashboard standards.
So I looked once again online, and found what I wanted in the UK, at a retailer called Speeding Co. UK.
So here's a picture of the unit.
Teebes, being as crazy for offroad mods as I am, bought into a mini-group buy so we got a few pounds off. But I didn't announce it here because there was no more discounting available from this retailer. And there seems to be no US distribution on this extremely custom item anyway. Too bad. And I guessed not too many other folks would sign up for it, being about $175 and all that rot.
But it has great cool value, and extremely digital to boot. Self-contained, 2 AAA batteries, backlight, thermometer, clock, and re-calibration control when you're sitting still.
More pics after installation.
