I recently got permission to detect the water at a private beach. The owner had told me that people have asked in the past but not recently. My 11” CTX coil took a crap 10 minutes into the hunt so I had to use the 6 inch. I Forgot my 17” and 5X10 but luckily I had the 6”. The shore line is about 100 yards long so I took my time and made 3 passes over a 3 hour period. As I got out deeper the sand got thicker and there were less and less signals so I figured the targets were out of the 6” range. I ended up with a fair amount of clad $1.96 and one buffalo nickel, no date. Only one ring and several junk pieces of jewelry.
