Electronic Inclinometer, Digital Protractor/Level/Angle Finder and Gauge Tools with V-Groove Magnetic Base and Backlight - Dust and Waterproof IP65 Precision Smart Level

No very handy if your trying to check degrees when there is a machine running causing a small vibration.

I saw this level and was excited at the concept. I use a level to setup my telescope and sometime is getting dark and hard to see a regular level. This had large numbers is bright and makes leveling my Telescope so much faster. I am very pleased with the ease of use and the construction, good quality. I may buy another one if I ever need a backup. This one will last for a long long time.

I bought this because I wanted to create a steady rising spiral on a model railway.Accuracy seems OK. I checked by switching the inclinometer through 180 degress and confiming the it read the same magnitue , but up instead of down.It does take a few seconds to settle on a steady value, but once you get used to that, it's simple to use.Reasonably robust too - it survived a couple of drops with no adverse effects (though the book says that you may need to recalibrate after that.)

There are VERY few times in life when a fellow needs a digital magnetic inclinometer. But... when one of those occasions arises, this is an excellent example of one to have. It works great, it's super simple, and it's cheap. What's not to love?

Fantastic addition to my tool box
