Well I got a huge surprise yesterday at the Inglewood test site! A few friends and I decided to run our machines over the targets and the result surprised me. Test one with a GPX5000 and 11inch standard Minelab mono all targets found except two, the same with a 4500 with the same set up. I ran my 4500 over the targets using my Coiltek 14 inch elite found all targets except one.another friend with a 5000 running a Minelab standard 11 inch mono didn't pick up the last two targets. A mate who was running his 6yo 4500 for the first time swinging a Nuggetfinder 12 inch evo mono found ALL targets clearly! All running 9 Gain.
