Greetings,
I have been out hunting with my ATPro. After doing some air testing I took it to a park and hunted a couple of volley ball courts. I was running the sensitivity at about 50%, Iron Disc. at 35 and the Notch Disc set to detect everything from mid foil on up. I used the Auto Ground balance to balance the machine and it balanced at 93. I hunted the first court in Std Mode and recovered several clad coins to a depth of about 4 inches. Nothing earth shaking since the detector functions pretty much like any other Garrett in the standard mode. The second court I hunted it in the Pro Mode. With the fast response of the Pro Mode I noticed that I was hearing more targets. I again found clad coins along with some trash targets, mostly aluminum foil and pull tabs. The deepest target was about 7"+.
My next site was a grass area that is next to the ticket gate of a ball field. It is a MEGA trash area. I decided to start hunting it in Std Mode. I left everything the same but I reground balanced and it balanced at 90. My first exciting target ID was a 85. I thought I had a quarter. It was shallow and when I dug it it turned out to be a flat rusty bottle cap. I remember seeing the video so I threw it back on the ground and switched to the Pro Mode. Sure enough when I swept over it, it no longer sounded like a good target. I then threw a quarter on the ground about 8" to one side and swept over it and it sounded like a nice clean high tone good target. I noticed several other iron bottle caps laying around so I hunted the area in the Pro Mode. Man was it noisy with all of the foil, pull tabs and iron bottle caps. I really should have turned the sensitivity down some more and maybe used the default coin mode. That might have reduces the noise from some of that junk a bit. However, I learned to listen for the clear tones and they would be good targets. The Pro Mode is going to take some getting use to, especially in trashy areas. However, I found good targets and came home with a handful of clad coins, quarters, dimes, nickels and pennies. Interestingly, I never dug another bottle cap. I did dig some foil, pieces of pop cans and pull tabs. I don't recommend trying out the Pro Mode for the first time in a high trashy area. It is a little scary.
God Bless and HH
