The worst of the red soil is noisy but not rediculously so. I dropped my gain to 6 and sens to 26 but targets came through loud and clear, and deep with the stock coil. I dug a number of metal trash targets at very respectable depths. The ground is not so bad that it effects depth in my opinion, at least not the way I had my machine setup.
With my settings on a scale of 1 to 10 the volume of a ground false might be 5 while the volume of a target would be 8-10 so its simple enough to ignore the lower volume false ground signals and concentrate on the targets.
If a person was trying to run their gain at say 8 this approach fails because the ground falses now sound about as loud as the targets. The temptation then is to lower the sens and then there goes the depth.
