What is the crowd's opinion of BenchMap?

From 3.5 billion comments

I like to use the BenchMap app for this sort of thing (https://play.google.com/store/apps/details?id=com.tsqmadness.bmmaps)

Doesn't look like there's one on the highest point of the lip, but a handful of them around http://i.imgur.com/bS74jIJ.jpg

Edit: this->thing

Here's an android app for that:

Not as good as the geocaching app, but the best I've found. The nature of survey mark hunting/monument recovery ("benchmarking") requires you to go more off of the NGS datasheets and a compass than any map anyway. A lot of the coords are not accurate so they use detailed written descriptions. But then you'll find descriptions of landmarks that disappeared 80 years ago, and have to really research to figure it out.

Some of those old missing ones have been the most fun. I found out there used to be a power plant and a small airfield near my home in my small town a century ago, that no one I can find knows about. Dug up old photos and town fire insurance maps in the process of looking for these old benchmarks.
