Several hours was 6 hours non-stop except for a couple of drinks of gator aid.By hammered I mean hunted a lot for many years by many different folks and machines.By trash I mean several nails and the like just about every swing in the area I found the coins in.The two cruddy Indians were actually in some burned ash material and appear to have been in a fire as well.The debris from a couple of buildings burned long ago and scattered over several hundred square feet make for very difficult hunting to say the least.
This area does not have much grass and what is there is long dead and dried out and the ground is very dry and I feel that is why I did as well as I did.Most of the coins were in the 5"-7" range and were almost masked by iron.Almost all were on the "iffy" side if you know what I mean.
This area is normally very wet gumbo type soil and iron falses like crazy except when very dry as it is now.Also very hard digging and the reason I did not post a pic of the back of the about unc. 1912 d Barber......Big scratch on back

.
I was using the pro coil with manual 28-30 sens.and factory coin mode with the big silver opened up at top right.As a matter of fact I had about every thing set to max with trash and dif. soil on.Deep and fast were off and I just went fairly slow, for me at least and listened for interesting peeps in the middle of all the feed back and then would stop and analyze them with the wiggle method and use pinpoint to help as well.
I am finding that if you have a very trashy site the time to hunt is when bone dry if killing grass or lawn damage is not an issue.
I want to be clear that this area was not going to be damaged from digging in the dry conditions ,not exactly a pristine park lawn lol.
I can and have hunted for a couple of hours more than once with nothing to show over in the clean part of the park.I did very well there back when I got my Explorer II and must of about cleaned out all the seated,barbers and Indians and boy was it fun.
Park was established in 1886 I believe,Ray.
PS I find that I can crank the sens. up in dryer areas without as much falsing as usual and get even greater seperation than normal.
