[QUOTE="Roscoe, post: 101549, member: 1615"] G'day karl, Try running machine in normal GB position #8.5 then when you hit a target then turn Gb to #4. I did a quick test with my spp and i would not be detecting in GB# 4 all the time you are knocking out a lot of good stuff on GB#4. For instance sweep over a $2 coin in GB#8 then switch GB To #4 and see what happens? I found that the $2 coin completely disappears in air test when on GB#4. At this moment i would be running on normal GB and only switching to GB#4 to test target. I only had the machine for 1 day so i will have to test more. :) John, I agree with you 100% this machine needs a Finer GB potentiometer. If you decide to fit one would you let me know how you do it. :) [/QUOTE]
