Last season I discovered the value of using the pinpoint mode for sizing and as a filter and I haven’t seen anyone else post about this feature(maybe I just missed it?). Despite my screen name, most of my hunting is parks, which tend to be trashy. I had read on the forums that pinpoint mode was good for sizing a target, so I began using it for that purpose in an effort to try to reduce the number of crushed cans that I was digging- man those suckers sound good, and in my area ring up in the dime/quarter range. It works pretty good for that purpose but I found that the sound a coin makes in pinpoint vs. the sound of other targets can be very different. In my ground, the sound of a coin will have sharp edges, whereas other items have smoother beginnings and endings to the sound. Being a coin shooter, this has been very helpful. Check it out and see if you see what I am talking about. Might be helpful....hopefully! Happy hunting, and Merry Christmas!
