Using negative ground balance, helps detect silver and copper deeper in the ground.
It actually depends on the machine. On an Xterra, the higher the Ground Phase number the milder the ground, so if you want to fool the machine into treating the ground as being hotter you have to lower the GB. On the 705 you have the option of Tracking with an offset.I always thought it was positive that runs the detector hotter. I definitely wouldn't be on this topic though as I've always used a detector with an automatic gb.
I always ran my F75 with the ground balance set at 65. The Omega will grab at around 65, but I usually lower it to 50-55, and on the beach set it in the 40's. Whatever your ground grabs at, lower it by 10-15 #'s and see if you get better depth.
With it not being a threshold based detector or having a true All Metal mode, how can you say that he hears everything?Especially with the AT pro because you already hear everything in the ground.

According to page 32 in the AT pro manual..." ...you may want to use the manual ground balance function to ground balance slightly positive to enhance detection of small targets or balance slightly negative to reduce detection of " hot rocks " terra cotta and saltwater."
Adjusting your ground balance to the negative has more to do with stabilizing the detector in a high iron or trashy environment.
Adjusting to the positive helps pick up small targets and could " possibly" increase your depth a little but if you are in trashy or iron rich soil it makes the detector less stable and more noisy. Ground balancing tunes the detector to your particular soil and going negative helps reduce interference from high mineralization , going positive makes the detector a little more sensitive but depending on your location or soil type you may just be making the detector more noisy than you would like. Especially with the AT pro because you already hear everything in the ground. I dont see how setting to the negative can help get better depth since what you are doing is essentially making the detector "less" sensitive meaning it takes more to set the detector off.
Using negative ground balance gets you deeper !!!!!!
As far as hearing every thing in the ground with the AT PRO it won't happen.
If you are using a DFX you can set it so you can hear most every thing in the ground.
