100TECH Universal Water Gauge Black

I like these relatively inexpensive gauges. They can be set for different input device resistance ranges and seem to be digitized, rather than purely analog mechanical units. I'm still not sure if they read continuously though, or if they're "quantized" somehow. I.e. sometimes the needle will jump all the way to the next major division. I have four of these - two for water tanks, two for fuel. You can choose different illumination colors, so originally I had blue for water and red for fuel. But the needle is also illuminated - in red. Cool, but it makes the gauge hard to read if red illumination is selected, which is the default. Easy for the other colors though.

Thank you

good
