Someone with a 3-D printer could probably build one cheaper but it works great for finding height.

The site glass and bubble level are very difficult to see. I may be too negative here due to the bright sunlight I tried to use it in so YMMV. Would I buy it again….no, but my eyesight could be a factor.

Got this to help me tell the height of a tree to cut down.I checked it against once it was on the ground and it was real close with in 4 feet on a 80-100 foot tree.

As a ham radio operator, I use trees to hold up wire antennas. This is a handy tool for calculating the height of the tie points of the antennas (80-m dipoles, off-center-fed dipoles, end-fed antennas, etc.). Few tools could be easier to use, including laser measuring devices. The problem with laser devices is knowing whether the laser beam is bouncing off the antenna insulator (to which I wish to measure) or something else nearby. With the tangent height gauge, all I need to do is sight the insulator through the sighting holes while keeping the gauge level by viewing the leveling bubble in the angled mirror, then follow the simple instructions. Oh yes, and there are no batteries needed.

Stamped sheet plastic, probably cost two dollars or less to manufacture. Mark up on this product must me immense. Should have taken the previous reviews more seriously before purchasing.

It's extremely difficult to use the bubble level because due to its arrangement while using the positioning system. This can greatly affect the height measurement.
