Made it out to the beach yesterday trying out a 9.5 concentric coil I just got from Ronandari for my V3i. Worked well, no fantastic treasure but found a bunch of lead weights, bottle tops, pull tabs, clad coins and fishing swivels etc. This coil works a lot better on the salt beach than the 10D2 the V3i came with! Don't get me wrong the 10D2 works OK on the beach just the concentric doesn't false anywhere near as much!
Thanks Ron.
Now if the rain stops sometime today I might get out to try out the 4x6DD I got from Ron too!I have just the spot I want to try it out at.
