Took the Deus out for the maiden voyage today

[Reeseb]

I hit a spot where I've had a lot of trouble with bottle caps with several of my machines. They are rusty, about 6 inches down and EVERYWHERE. I was in 4Khz and and 0 Resactivity to get as deep as I could and for the first hour, I was digging bottle cap after bottle cap. Then, after I got used to some of the coin VDI's I was getting, I started ignoring anything that bounced above 82. This got rid of the bottle caps in a hurry. Probably not the best way to hande those pesky things if you want to dig big silver, but it sure allowed me to concentrate on coins.

Incidentally, I met a guy with a Minelab SE Pro out there and we tested our machines on a 9 inch deep clad dime. His couldn't hit with full sensitivity and my Deus got a consistent hit both ways. I was pretty impressed. Both machines had 11-inch coils.

I'd be intested in knowing how everyone else is handling bottle caps.

I have used the switching from a 4 KHz to a 12KHz program, XY screen and raising the coil (numbers will drop). I think there was something else that I tried...

Using two different frequencies and seeing the numbers staying about the same is the surest way to determine that the target is most likely a bottle cap.

When I hunt in 8 kHz and then switch to 4 kHz the coins will drop in number appropriately; the bottle tops don't.

Thanks for the tips! I will try it.
