I used a pinpointer for the first time the other day and loved it. I need one that will pinpointer that will do its job without having to actually touching the item. It needs to be water resistant as well for beach combing and inclement weather. I looked at a kellyco Auto max Precision V.4, it appears to fit the bill and it is 89.00 dollars. What do you think. I am also new to the metal detecting business as well. Thanks in advance.
