📐 Cardan Leveler with Enhanced Precision and Horizontal Bubble Review

I didn't know what to expect but I tested it on a perfectly flat surface checked with carpenter's levels and it was accurate. I use it on a tripod. The double band works very well.

This spirit level would be perfect for my scope if the magnetic base would stick to the scope's elevation adjustment knob. The visor is made of aluminum, so the spirit level is not attached to this metal.

I bought this at first because it was small enough to put in my pocket (just like a coin or small marker). Great concept but the element is too small to read the slope more than the small spot the marker covers.

The one originally ordered had too big a bubble like it was leaking liquid. The return was easy and the replacement came quickly. The second was much better - still a bigger bubble than the advertised picture, but apparently not bad.
