It is called "Benchmark Hunter Tools" - I like the USGS TOPO overlay part of the KML or kmz file

    I hardly need the Benchmark finder because with my GPS, GNSS program, and local CORS, I can get good precise positions both vertical and horizontal and have tested it thoroughly with local benchmarks to prove it precise. I like the TOPO overlay for undeveloped areas but it is only good for comparison with developed areas. It needs a date of imagery like Google Earth now offers to qualify the topo. The other day I had to reload it. So try it and let me know what you think.
