Got the 6.5" x 9" Concentric coil yesterday, and had today off, so after a Dr's appointment, I put it on the AT MAX and headed out to the woods.
The coil seems to be about the same weight as the 5" x 8" DD coil, and slices through the snow with about the same friction. I did a quick air test in the house prior to removing the 5" x 8" coil on a penny and the same with the 6.5" x 9" after it was put on the MAX and the machine was rebooted, a requirement each time you switch to a different coil. I got about 3/4 - 1" depth increase with the concentric, just as suspected. I will do some measured air comparison tests with discriminate mode vs. true all metal mode with both coils at a later date.
My first good signal in the 80's, larger then a coin, turned out to be the buckle on this ladies shoe. I tore off the buckle with the stones on it to take home for some possible future use. During the hunt, I switched between true all metal mode, discriminate zero disc. and a custom mode with numbers beginning at 60 on up, specifically searching for high conductors such as silver or copper. I did manage to find 4 copper pennies, which was surprising good considering I had to contend with about 4" of snow. Bottle caps were easy to identify, as they read 60-75, bouncing around, and ID'd as iron when the iron audio feature was engaged. Typical of concentric coils, it produced a more accurate ID over targets.
The day also had some bad karma episodes. A stolen dufflebag with a bracelet, a snake on a stump, and a box of unused 1cc insulin syringes. Lots of other things like old clothing, smut books, pot & pans, a channel changer and toiletries. A real mess is what it really was. All the junkies move out of these areas at this time of year for special shelters to house them down town.
Here are the finds from today's hunt. I dug most targets not registering as iron using the iron audio option. I pretty well guessed the pull tabs, as they read at about 53. The cap screw did read in the middle 80's, so I had to dig it!
And......I am preparing about 5 1/2 LBS of some brown sugar, spicy beef jerky! Can you smell it!
