I have a Gold bug pro, version 4 with a 5" and 5x10 coil. Here is my problem. It almost never gives me a good target id in the ground. In my soil it usually is ground balanced between 78 and 85 mostly about 81/82. In the air I get clean targets ids 57/58 on a nickle 87/88/89 on a quarter until out of detection range. In my test bed newly made (GB 84, 5" Coil) I get nothing solid on a 4" nickle. It shows a great target but vid jumps from 20 into the 80 and everything in between. Both coils different sensitivity settings, GB offset. Totally undigable target. On a quarter at 4" the vid gives me a weak jumpy 80-85 which I would probably dig, at 6" 20-90 jumpy signal. Dime 4" barley there jumpy signal and 6" nothing. These results seem to be the same in the field.
Yesterday I went hunting with a buddy. He had an AT pro with the smaller dd coil. I got a signal on my GBP with the 5x10. The signal was loud enough but jumpy from disced out to occasional 70s-80s. Something I would never dig in a park. I figured canslaw. The area was so clean we were digging almost everything. I had him come over and test it with the AT PRO. He went over it and said he would definitely dig that, probably a nickle. It was a new drop nickle about 3"-4". I also got a signal that day that said jumpy dig 8"down. Dug down 8" big hole with relic shovel. Target still in hole 8" down. Dug bigger deeper hole, target still 8" down in bottom of hole, dug some more same thing. Same signal the whole time, I gave up. Im thinking it was a strange patch of mineralization, or something like that.
I also get at least double the depth in all metal mode which is awesome for nugget shooting but doesnt help much in normal hunting. 5" coil hits a nickle at 10 inches at full sens, which I find amazing. With this good of an all metal mode, how can the disc be so weak and erratic? The machine can obviously see the target very well. At 4" air test in all metal it screams, at 4" disc mod in air it says 57/58 nickle, at 4" in ground it says dont dig, trash.
Do I have a problem? Should I send in my pro for a checkup? Has anyone else had similar problems? Am I nuts and need to learn my machine better? If you are reading this Mr. Johnson, anything?
