I detect a lot in parks and places like that that are sometimes loaded with steel bottle caps. They will hit at around 94 most of the time. same area as a quarter. You can do a few things to determine they may be a bottle cap like raise the coil, sweep the target at the edge of coil, etc. Its not fool proof but works pretty good. But the problem is when you are in an area with a lot of them I find myself spending too much time having to analyze every one of them. I think I found a good solution to the problem.
I start with the Deus fast program then modify it. I will turn off normalization and run in a 4khz program. That still puts the bottle caps in the 90's but puts the quarter around 83. I then set a notch above quarter zone to get rid of the bottle caps. I could possibly miss a half dollar or dollar coin but the chances of one being in the park are pretty slim anyway. This is not a deep silver program but something to wade through all the trash. I like to use 5 tones and set high tones up for the nickel and zinc and above coins. It actually works pretty good.
