Cache is not at the posted coordinates, a benchmark (JV4124) is.

Recently I was caching as usual when Georick402 brought to my attention the concept of "benchmarking". I had heard of surveyor posts as someone came to recent survey our property line, but had never thought of it as a game or addition to geocaching. I did think it was very interesting and did some research, finding that geocaching.com allows you to log them just as if you are logging a find on a geocache. Apparently, there are even challenge caches for finding them. I don't have any fancy GPS navigational devices other than my cell phone, so was spending hours trying to find an app or some other way to get these benchmarks on my phone. I did actually find a few ways and I will share them with you down below. As the video, I put here said, benchmarking is a "scavenger hunt with a historical twist", so basically if you like geocaching you may have an interest. I know some cachers in the area like Kcfatts and Seadog have been logging some around this area so I was thinking why not bring these some more attention.
If you have no idea what a benchmark is or how to find them:
1. Introduction to benchmarking https://www.geocaching.com/mark/ (You will be able to download the LOC file at the bottom of this page).
Please note given coordinates can be hundreds of feet off and require the use of past "recovery logs" to find. (Ex. "63 ft northwest of electric pole 7732-47922")
2. Video - How to Find https://www.youtube.com/watch?v=TbrNcizQ7sM
3. National Geographic Survey https://geodesy.noaa.gov/datasheets/
How to get benchmarks on your phone by means of cachly:
Step 1: Download the LOC file off geocaching.com
Step 2: Download GSAK (http://gsak.net/) and upload the LOC file
Step 3: Export file as a GPX and import that GPX to dropbox
Step 4: Open cachly, "more", "import from dropbox", "add to list".
There are more options at the bottom of https://www.geocaching.com/mark/.
About this Cache:
The cache name says it all, the geocache will be within a 5-foot radius away from the benchmark. You can check the most recent Recovery Logs at https://www.ngs.noaa.gov/cgi-bin/ds_mark.prl?PidBox=JV7122. After finding do not forget to log this benchmark as a find at geocaching.com!
ATTENTION: Please do not remove or tamper with the benchmarks, they are meant to permanently stay in place. If you find a benchmark out of its original location please leave it as is and contact the agency that owns it.
To be sure of your coordinates there will be a checker on the geocaching.com website.
