Hi Steve, thanks for the feedback.I bought the detector, brand new 2 months ago so not sure if its the new model or not.I'll keep you all posted on the outcome, i have vented my frustration & appreciate the support & feedback from your fourum members.Its been a cool adventure so far, checking out all the old mines & workings, it has opened my mind 2 a history i have only read about, now with 1st hand experience I can appreciate the history of gold prospecting in the olden days. Apart from the issues i have had with my sdc it has been a rewarding journey.Good luck,& full pockets
