I often hear people talk about the "erratic" behaver of the 75. Outside of EMI from other detectors,power lines etc that you use the frequency shift to eliminate. I think i know where this is coming from. This is just a shot in the dark to 75 users but are you using the fast grab ground balance enough? It almost seems like people only do it once at the beginning of there hunt and thats it. I tyred to replicate this on my last park hunt. I only GB once and when i moved to different area different dirt it seemed to be erratic. Fast grab calmed it down and the way i went.
There are quite a few machines out there that auto ground balance. The 75 with fast grab makes it easy to do on the go. A good ground balance is key to depth, stability and ID.
