The polar meter is a "unlikely" design that summarizes level, compass and inclinometer.
The Polarie Polar Meter from Vixen makes setting up aligning the Polarie Star Tracker faster and easier. It features a large, easy-to-read compass to orientate you correctly, a bubble-level to set up the tripod, and azimuth and altitude scales for proper and precise polar alignment. The Polar Meter attaches to the Polarie's accessory shoe. The Alt scale shows in 1° increments, and the Az scales is in 5° increments.
It can also be attached to accessory shoes such as cameras.
