Hey everyone. I been wanting to know if using beach mode on my detector will help me in black sands and bed rock at a local river here in California to prospect. I am still new to the sport and am learning as i go. I want to know if it will help make my detector more stable. To me it seems some days my detector works really good and others not so good. I have found to do a factory preset before i go out helps. Also can someone help me to set it up right is there any videos where they show u how to set one up for prospecting?
