Headed out this afternoon for a couple of hours to a local school yard. Lots of pennies, but good experience. Learning little tricks not in the manual. For instance, it's hard to de-tune a target with the coil on a large target. The type of mineralization in the ground can have an effect on the VDI numbers of a particular target. I switched to the concentric coil for this hunt....much better ID then the DD coil. Glad to pull out a ring....it read in the 60's, but sounded good and hit hard. When pinpointing with the concentric coil, keeping your finger on the pin-point button and pulling the coil towards yourself, the faster the audio cuts out, the shallower it is and it's usually a good target. Most of the pull tabs give a sort of double bleep, in the 70's, making them easy to ID. Targets with a bleep one way and non the other way are pretty well junk. So far, it's turning out to be a decent coin shooter.....
