Silva Clinometer with Two Scales - 8x10 cm Inclinometer with Fine Tune Scale ± 5° and Scale ±35° - For Checking Heeling Angle on Sailing Boats, Power-Trim Boats or Other Type of Vehicles

Wanted to leave a review covering this Silva Clinometer as I couldn't see any that provided me with the answers I sought.The items isn't 10mm thick entirely. The two tubes containing the balls are raised (10mm), the rest of the plate is circa 5mm.The rear of the plate, which is white is a piece of solid plastic. Which appears to be circa 1/2 the depth of the base plate, thus I reckon it's 2.5mm thick. It doesn't feel thin, skimpy, or any possibility to place a hole in it unless you've done something seriously wrong with a tool, or upon mounting!!I tried flexing the plate, it doesn't flex.The 0 - 5 measure doesn't appear to be dampened inside, BUT, the 0 - 30 does appear to dampened.Good size, easy to read. 8 x 10 cmI will say it's expensive versus others I've seen but considering you get two measuring units into one device making it cheaper than buying two should you need / want precise information from 0 to 5.

Excellent.
