I'm almost willing to bet Whites will send me a replacement free, that's just the kind of company they are. I didn't know they made a thicker one, I told them they should make it stronger.
I have the DFX set up in a relic program I made called "Civil War 1865". Of course I have included my own personal preference settings. I also found I had to open up the discrimination a little more than the relic program is set at, because at the Whites settings it would not detect iron grape shot with a good response. And because I'm using a DD coil, I bumped up AC and DC sensitivity slightly. I can usually hunt with the gain set at 4 if I'm not around power lines but sometimes the ground changes a littler hotter and I have to set it back to 3.
I dug a bullet at 14" with this set-up using the big DD coil. The bullet was only responding in one direction but it was a good repeated response so I dug it. The bullet I dug yesterday by the creek was pretty shallow ~4" in very hard dence ground from stream overflow. Most of the 40 or so bullets I have dug here average 6-8 inches in sandy soil... I love bullets but a CS plate would be a welcomed change!
