I assume stability will be okay?

Ground is seldom highly mineralised, soil is often very damp and not very often bone dry. Coin weight in silver from 0.6g upwards. The land is either pasture or ploughed.
I was going to purchase a previously modified GPX4500 but it is no longer for sale so I am looking at the possibility of having the latest full upgrade done.

With you modification, based on the above, what would be the approximate setting for both front and rear gain? And what soil timing do you believe would be best, I am assuming Normal but I may well be off track.
woody:
It depends on the ground as to how to set the gain, bur as a general rule I crank up the front gain and tame the ground in the back menu gain setting. I use normal timings if the ground allows.

I understand it depends on the ground but initially where would you have the rear end gain in order to crank up the front gain?
woody:
On my 4500 i run my back gain on 5 but on quiet ground i crank it to 8
