Quest Skyscope Altitude Measurer - Q7812

I was surprised how accurate the readings are when I tested it against my known launch angles—dead on every time. The whole setup took maybe two minutes out of the box.

The dial markings are crisp and easy to read, even in bright sunlight. I used it to check the angle on my latest launch and got consistent readings every time.

Used it for the first time yesterday on my balsa glider and the scale markings are easy to read even in low light. Takes a little fiddling to get it level with the wing, but once you do, the reading feels solid. Works exactly as advertised for the price.
