Hi all, I live here in central Pennsylvania. Ground conditions here are not the best in terms of detecting. A common consensus here is that a typical IB detector around here can only realize about half the depth using disc modes in the ground as compared to the all metal modes. I own several Whites detectors and a Shadow X5. The problem is the same with all units that I have. Coin sized objects buried at a foot or so are detectable ONLY in the all metal mode where as in disc modes, 6 inches is about tops. I Have a Magenta PI kit detector that I put together and it goes just as deep as my $1000 units! (in the ground where is counts).
Here is a simple test: Find a small piece of ferrite loop stick 1/4 diameter X 1/4 inch long. Ground balance your unit to the piece of ferrite. In the disc or all metal modes you should NOT be able to hear the ferrite rod anymore. Put a small coin BEHIND the rod and run it over your coil. In every detector I have tried (except a PI unit) the piece of ferrite will hide the target in the disc mode but NOT the all metal mode. Does anyone know of a manufacturer who can claim that their products will NOT loose depth in mineralized ground in while rejecting only iron?
Thanks..
