ctx false readings

[ginseng]

I have had the ctx for around 6 months now and have used it occasionally on my 13 acre parcel.
I've found a lot of scrap cans and pie plates, shards from buried metal roofs and one 1983-D lincoln
I was able to find a property line stake that was buried, so score 1 for the operator/hardware unit.

Not too impressive, but I don't blame the hardware...

However, I have found that I get a lot of signals--- that when I dig a hole -- seem to disappear. Using a Garrett pro-pointer I get nothing and using the CTX I get nothing once the hole is opened.
Could this be a sensitivity problem??? I have sensitivity on auto, but perhaps I should put it on manual.

This seems to happen no matter what pattern I use; Minelab patterns or some custom patterns downloaded from this site.

Any suggestions??? I don't expect the ctx to find what is not there, but I'd sure like to have the CTX not indicate a target for what isn't there either.

BTW, the unit has been updated with the latest software from Minelab as well as the exchange 2 software.

Thanks in advance

That happened to me some before I started investigating signals vigorously before digging. First move the coil several times over the target to make sure signal is repeatable. Then pin-point the target and make note of the location. Then turn 90 degrees to the target and sweep coil over several times again. A good target will give a repeatable signal that should be similar to the one heard initially. Then pin point target again. It should pin point to nearly the same location if it is a good target. I walk away if either the target is not repeatable, not repeatable at 90 degrees, or pin points more than 1-2 in different at 90 degrees. I probably leave a few good targets this way but I dig probably 90% less trash and have more time to search for the good stuff.

It sounds like you need to find a better place to hunt too...
