Trying to knock out targets using the Discrimination like a VLF doesn't work like a vlf. So.......here's what I dofor best results on thre ATX:
Pay attention to the audio. It will give subtle clues as to a rusty bottle cap vs. A coin. The coin will give a smother audio, the rusty bottle cap will be more harsh.
-Shallow nails give multiple audio blips. A coin does not.
-Use the iron check....it does work in the upper 4-5 inches, depending on the size of the target
-Copper and silver will give a low high audio sound (yes....there may be exceptions)
-Gold will give a high low audio sound. Many of the other targets can give either, including iron. (yes....there may be exceptions)
-Large targets will give a longer swing arc over a target compared to a small one.
-The audio is modulated. Deep targets give a quiet signal, shallow ones can be very intense
-Take discrimination thought out of the detector electronics, and apply that same type of thinking to location and best place at location with the greatest potential to find a decent target vs. areas thast are just littered with junk. Also, consider hunting hunted out areas, as a PI will often find targets missed by others.
-Hot rocks should dissappear with turning up the disc to about half
Thats what I have notices so far. It allows me to hunt for old silver and copper targets, omitting 70% of targets indicating gold, iron or other unknowns. It allows me to ID tin cans as large targets, so I leave them alone. It allows me to leave a lot of nails, wire and iron alone. if searching for gold, I can disregard the low-high signals. If I want to dig old targets, I dig the soft sounding targets. You want to dig targets in extremely high mineralized soil, use a PI and put a VLF detector in the trunk.
You can't use a PI like a VLF, nor should you use it in all locations. In the right location, in the right persons hands in well thought out places it's a killer!
I am sure there are other ways to utilize some discrimination on the Garrett ATX. It should be interesting to hear about more as time goes on, and I will (pin) start an on-going list
