Drive In Theater & Pinpoint mode

[cheesehead2]

Wondering if many people have hit old or operating Drive-in theaters. If a person wants to learn some about discrimination, these are the places to go. I have found well over $130 in loose change. 6 silver rings and probably missed 3 times that since going there. I was fortunate enough to have access to one the last couple of years. I cleaned allot out with my DFX and this is where I tested allot of different detectors and settings. I brought the V3 there today. My normal program I've been using in the city parks was not working here.
Won't go into great detail but Ended up running @
10 Hz instead of 5 Hz for ground filter, seemed to stabilize the false signals.
30 for recovery instead of 20
Turned RX gain way down to 3 and Disc @ 70. Even though it is low mineralized soil.
These Three things made a world of difference for hitting coin. But still had issues.
So I wanted to share what I found. That in spots there were way too many pop tabs, bottle caps and such to even distinguish a Quarter laying on top of the soil. I Would get broken up readings no matter what I adjusted.
I then set the V3 up to pinpoint with trigger forward like on the DFX. I run Three freq. and have the meter with All Three Freq. bars showing. I basically ran like this with trigger forward and watched the screen close. When I would see the 2.5Khz green bar open more than the others. I'd zero in on the target and find a Cu. penny,dime or a quarter every time. I could not get the machine to verify this while operating in search mode due to the amount of trash around.
Granted this was extreme conditions with trash but I thought this was pretty amazing to be able to search like this with all the trash around. The signal would change within 1/2 inch or so. Using the dx1 probe also helps while digging in these conditions.
Found allot of clad, probably $4 worth, One 1947 Dime and One 1946 Wheatie today doing this at this place.

There were two in the town I live in. Almost no one knows that there used to be two drive-ins here. One has a "metroplex" built over it and the other has a neighborhood of small 2 br 1 bath homes built over it. It took me several years to nail down the site of the really old one (where the little houses are) and I haven't asked permission to hunt any of the yards.... It seems there is always something else to do or somewhere else to hunt. I think I am going to get an old guy I know (he is the one who told me exactly where it was. He told me he worked there as a kid) to show me exactly where the gate and concession was. Maybe i'll get around to asking to hunt a few of the yards this season, it could be interesting. This drive-in was active in the 30s and 40s. The one where the theater is was in business after that. There is a small patch of woods behind the theater, I should give that place a try nex week before all the weeds pop-up.

That is interesting about setting the analize screen to show the three bars, then watching for green to dominate, good idea!

I'll let youy know if I get to it. I have so much stuff that needs doing right now... arrgh.

Howdy,
I have hunted a certian drive in 4-5 times in the last 15 years with my Whites Spectrums and XLTs...The first time I had a ball and found silver and lots of 40s to 70s change...But the family that owns it does not like alot of bother so getting them to let me in often does not work well. once in a while i'm ok. Nothing is very deep as everything sits jut below the surface. The whites always pinpointed well and as long as you dont dig any wires your its easy.
lots of luck.
