Because I as well always wondered what GB notch actually does (I never use it).........after watching the video Beepsilver posted, closely, I notice that he ground balances the machine by the pumping method, then he wiggles the detector and it falses, the number he manually sets the GB to is actually lower than what the machine says it is, meaning the machine read the ground at 85, he had it manually set to 82, which made his setting a negative one which will produce a lot of falsing, he applied the GB notch and it became a lot more stable. So, my question is, because a negative GB will in theory give you better depth / sensitivity, how far can you set the GB below the actual numerical number, still apply GB notch and have the machine run smoothly and properly, kinda saying I wonder if it was set too much in the negative side (actual GB 85, manually set to 65) if it would pick up everything and give the same signal like a PI machine? Things to ponder while I'll wait for spring....
It depends on a few things as far as setting GB below the ground reading. EMI will be a consideration as well as how packed the ground is with targets - black sand, the list goes on....Only way to find out is to keep setting GB lower and lower until you start digging too much iron. You will have the machine at it's hottest - and although you will be getting a little extra depth and sensitivity the same GB settings would differ from day to day slightly.
Have commented on this vid here in the UK, have tried to mimic the situation shown with 3 different Deus machines, and in now way shape or form could we get the machines to sound off when shaken?
