Hi guys, I am new to the forum and just got my first White's machine a few days ago. It is aVX3. I have used a Garrett GTI 2500 for about 10 years now and thought I knew how to metal detect, but the VX3 is a whole different animal. I have taken it out 3 times now for a total of about 6 hours swing time and I haven't yet figured out how to shut it up. I have tried repeatedly to manual ground balance and have adjusted the rx gain way down in many different soil types and program modes but it still chatters more than I think is acceptable. I am using the stock 9.5" coil and I must admit some of the soil is highly mineralized, containing some iron ore, but I have hunted it before and was able to adjust the Garrett to a tolerable level. I am impressed with the depth of the few targets I did dig with the VX3. I am looking forward to learning this machine and would appreciate any advice you might like to share.
