Me and brother hunt together under the alias " Mayor Mcdigger" for the purpose of this website. One person swings while the other digs. We can recover more objects faster and cover more ground this way. We use the whites M6 with the stock coil. The capped dime was about 7" deep and just barely audible. The VDI was jumping all over the place. I didn't think anything of the target and went on swinging while my brother dug. I heard him make some weird gasp of air and yell silver. I thought maybe a merc or another Rosie. " I don't know what this is" he said. That's when I saw it and couldnt believe my eyes. Seeing the fine details I said " Don't rub the dirt lose, I don't want to scratch it." He proceeded to put the coin in his mouth to suck the remaining dirt off. I was laughing pretty hard at that point. I mean that's one way to get your daily minerals. I feel like the M6 is a great machine when it comes to coinshooting. But with the stock coil I feel as though there are targets I just can't reach or hear. The deeper flat buttons were hitting a VDI of 8. Needless to say there are very few tones left there that aren't iron. I'm looking into a new coil so I can go deeper. Any other M6 users out there that have any suggestions. Thanks guys.
