New DD Coil

[Idaho PRB]

Well,
I got my new DD 10" 7.5 kHz coil on the 10th and have been using it every chance I get. My real test was to be my "dug out" front yard. So far I have found some deep wheats and some memorials that I had missed and tonight I pulled out a 1925 D Mercury dime! I was jazzed! I also found a key and some copper washers and a lot of this stuff is around the 8 or 9 inch depth. The merc was about 7". I think a lot of the stuff I'm finding is either deeper than I could go before or next to iron signals. I have been going REAL SLOW in all metal mode and 99 tones. The deep stuff is giving me numbers that are bouncing around because of the iron interference but the high notes come through periodicly too and then I dig. I am digging anything that gives me a non ferrous reading that repeats at least one way and sometimes real faintly. I have found wheats and nails in the same hole at different depths. I just take a small section each time and go over it thouroughly and super slow. I really like the coil.

I have a 10" DD on the way. I've read that some think the extra weight of that coil makes the detector feel significantly out of balance. Has that been a factor to you?

I use a 10" coil also but to counter the weight problem, especially if I plan on swinging for several hours I use Doc's Swingy thing, it helps you swing for longer periods of time without your arm getting tired.

Congrats of finding more coins in what was considered "dug out". A DD coil, combined with a slow sweep speed, will produce good targets in sites that many others have given up on. Using a form of zero discrimination and the multiple tone mode (2 has proven itself to me over and over again. Once you get done sweeping the entire yard in one direction, try it again running perpendicular, then again crosswise. The DD coil just might turn up a few more coins that are being masked in one of the previous directions. JMHO HH Randy

You know, I don't think that coil is heavy. I think the others are light No, really, I was concerned about that too but it's not bad at all. You will feel a little burn in the bottom of your bicep for a while but once you get used to it it isn't a problem at all.

Idaho...the more you use the 10.5 DD MF coil the more you will like it. I swing it about 90% of the time and I also use Doc's Swingy Thingy. A couple of tips that works for me. The first thing I do with the DD when starting is lowering the sensitivity to 0. I then noise cancel and ground balance. I then run the sensitivity back up to 30. If there is any chatter I reduce the sensitivity by one nunber until it settles down. Very seldom do I go below 25. Pinpointing the DD I click on pinpointing and gradually move toward where I suspect the TID to be. When the front of the coil reaches the target I stop and mark that location for digging. I find this to be much more accurate that using the center of the coil for pinpointing. HH TomB
