Yeah, I found my first class ring in shallow center...it was a girls, 1997 and I got a hold of her to return it...I figured she was throwing somebody out, but no, she said she lost it at night out drinking there with some friends..it hit "pulltab" and was 4" deep...never got a nickle out of her for my trouble either...I found a 1910 barber dime right behind second base in the grass that was a good 7-8" deep. found a lot of clad along either baseline out to the fence...seems its a good place to sit for baseball clinics or something...found a heavy silver ring right past first base...So to sum it up, I work the outfield where the players are positioned, I work the outside of the fence where there are good vantage points, (not necessarily the bleachers) I work the shallow outfield where the shortstop and second base play, and anywhere around first base of course gets a lot of traffic...then, think of deep hits to the wall, or where diving catches are likely to happen...try to find where the girls play softball, (they usually play shallower than the guys, at least they used to) and sweep the shortest path from the field to the parking area (gotta nice 14 k there this spring) If theres a concession stand, sweep off to the side, or an area where a peson is likely to walk after purchase to hog down a hamburger, (not necessarily the tables) ...you will get coin spills and stacks, so if you hit one signal, sweep dilligently in that area a little. (just got a 4 quarter tight stack, with a outside dime along the first base line this week) ...It takes a long time to sweep any sports field, but based upon the dates and depths and locations of your first few finds, you should be able to tell if somebody has been there detecting in a while, if the most likley areas are picked clean, go with an obtuse strategy and search in spots that make sense, but are not likly to be hit, like even the trails that kids have used to go from one point to the other outside the fences...So I guess just sweep all of it to be safe Ism!,
Sorry for the long post, HH
