Stick with it!
When we first started, we looked for ones that have been recovered recently and if the data mentions that there is a survey marker sign or post in close proximity. If we could find the survey marker sign, then there's a good chance of finding the BM. Once the BM was found, we "practiced" with the logs -measurements, compass readings etc, to get a better feel of how to read/interpret the data.
It gave us a good foundation of what we were looking for and how to go about finding BM. We are now expanding our horizons to attempt to find ones that haven't been recovered in a while. No luck yet, but its been a fun ride so far!
Even though I'm fairly new to this, I noticed that this a great group of people here who are always happy to help out.
