Coil Choice - Depth and Separation needed

Canewrap

New member
I know of a couple of sites that heavily laden with iron from 7-8" deep and the good targets are mixed in and are on average at about 8" or slightly deeper. I'm using a Tejon and I need a little advice on what coil to buy to supplement my stock coil. Because of the depth of good targets I have my doubts on the 5.75 widescan, so I've been looking at an 8" concentric or 8.5" widescan. I can't afford to buy several coils right now or this would be a moot question. I'm hunting in the woods (solid coil better here anyway) with moderate ground. Anyone with a similiar experience that can advise me on what coil might be good for this? Not really interested in the 5 X10 coil as I really don't think it will get the depth I need. I am digging up some of the iron to aid in unmasking, but you can only take so much of that before you just give up. So, hopefully someone will be able to help me with this.
 
I think you definitely need a DD coil for that kind of place to help with the separation.:)
 
I can't advise you on coil types for your Tejon, as that's not a machine I've used. But just want to point out (you may already know) that ......... generally speaking, you're going to have to deal with trade-offs. You want a machine that goes deep (understandibly) yet you want one that averages and separates well at the same time (understandibly). The trouble is, any machine/coil/setup that's going to go "deep" usually lags in the separation/averaging dept. And any machine that separates and averages well (ie.: see through and around nails, etc...) is generally wimpy on depth. The reason is simple: Any machine that goes deeper, is by definition "seeing more ground" and thus, seeing more targets, and trying to miminize the affects of minerals in that scope/field it "sees".

I wish there there were a machine that excelled at both, at the same time. But you're going to have to settle for compromises.
 
it is possible that the new g2 may be that machine!..only time will tell!..people are reporting "outrageous" separation,and
'decent" depth in iron with it!..looking forward to spring,and "possibly" a "killer" coin and relic detector!

(h.h.!)
j.t.
 
I've found I definitely get better separation with the DD coils. I agree that you probably won't get as much depth as you need with the 5.75 or the 5X10 as the DD design generally gets around the depth you'd expect from the narrow dimension on the oval coils. However, if the iron is as prominent as you're saying, I don't know if there is any easy way out other than dig the trash in a small area at a time and then pursue the goodies.
