[QUOTE="AVXVA, post: 669250, member: 22410"] How is everyone's winter going? Summer here has been remarkably bearable--no complaints. A couple of questions! With the GEB circuit turned OFF (Ground Balancing Knob = Inactive) the PulseScan TDI ground balances using it's internal circuitry alone. Is it possible to use the Threshold to quasi-ground balance? That is to turn the Threshold way down so the machine is mostly silent. The TDI comes to life over a shallow target doing this, but am I kidding myself? I am seriously considering spending a stupid amount of money on a Detech 32" Concentric coil. I need 5 or 6 feet or more of depth to located football-sized or larger chunks of meteorite in western Kansas. And the ground is really dry. My VLF isn't cutting it. Am I wasting my money? Does anyone have experience with these super-sized coils on a TDI? Thanks! Rob [/QUOTE]
