I bought a new Fors CoRe last week and had it out over the weekend. The unit I got doesn't seem to be functioning properly. I don't think that it is ground balancing correctly, the pinpoint depth isn't even in the ballpark, and all targets that ID as an 82 with a nice tone are rusty iron. I have a lot of experience with other detectors in the past including the Deus and the iron problem is the one that concerns me the most. When I see a target of 82 ID and the tone sounds good even when I swing over it at 90 degrees that turns out to be a rusty nail or bolt it seems that something isn't right. Any of my other machines would give a false high tone one way with a high wrap around ID and sweeping at 90 degrees the target will disappear most of the time. Not this machine.
The issue with target depth was apparent when I tried hunting a school ground that I've found a lot of shallow clad in the past. I got a target that ID at 91 and in pinpoint it showed 9cm deep but the quarter was actually right on top of the ground. The next quarter that I found also ID at 91 and pinpoint said it was 20cm deep but it was 2 inches or less in the plug.
For those that are going to ask, I was running the CoRe in D13 with all stock settings. I appreciate any input on this machine. I bought it figuring that it would be great at the iron infested sites I'm usually at but I am disappointed in the way this unit is running. I'm ready to return it for a refund.
