I hunt lawns,parks and other public sites and I hunt them over and over and eventually most of my detectors get a shot because of boredom and I just love learning and using different detectors.
I found a ton with my Vaq that my original cheap bounty hunter missed.
I found a ton with my F2 that my Vaq missed.
Found a bunch with with my Compadre that my others missed.
Found a ton with my F70 that all the others missed, found a mess with my Nox that everything else I used missed.
Went over sites I but hard with my Nox and still found great stuff going back over it with my F70.
I see a pattern developing, here.
For me things change out there all the time, I find different things in the same sites on different hunts depending on the moisture content of the dirt.
I find different things at the same sites by using different coils on the same detectors.
I find different things at the same exact sites using combinations of all my detectors and coils by hitting these sites from different directions.
I never believed that any site is truly ever hunted out and have been warned off sites by a few well meaning detectorists who hunted them to death over the years with some very high end detectors and years of experience that have told me they, and their friends, got it all and there was nothing left to find.
One guy said that to me when I first showed up to a small park and noticed me but I told him as long as I was there I might as well give it a try and thanks very much for the warning.
After a several hunts at that site over several days the guy stopped by again because he lived in the neighborhood and greeted me and asked if I found anything.
I said yep, a few silver coins, some nice silver rings, an actual small version Harry S. Truman inaugural coin from the mint and a whole bunch of clad plus a few other cool things.
He was skeptical so I pulled up the forum on my phone and showed him pictures that I had already posted in my F2 album of those better finds.
He looked at my little F2, shook his head and practically accused me of lying.
He had supreme confidence in his detector and abilities, I guess.
Since then the most I ever do with other hunters that stop by my sites is small talk since life is too short to argue with the clueless.
