Hi, I'm a new member here but have been detectecting for around 12 months using a Garrett AT PRO and a Euro Tek Pro. I must admit when I first used it on a wet beach it went mad, that beach by the way was at Paignton. This beach is very mineralised hence why it went mad. Over time I have learned it's ' beat ' as so to speak and after reading much on the net forums have started enjoying it on the beaches down there. I have in-laws down there, we visit every Xmas. I couldn't stop myself, I would say just going for an hour or so, 5 hrs later loaded with finds
and a big grin I would return. Found my first rings this xmas, one gold one silver. It will get noisy but just remember to GB every time you move to different conditions in the sand. I used the small pro coil 6" in pro zero, iron audio on, a bit noisy but you will here the better signals through everything else. If Hot rocks start to show try adjusting GB to the negative a few times. Keep at it i did and I'm well happy!
Good luck.
