One odd thing I've noticed with the Deus 2 is where the deep iron is coming in. Not only are they at the high TID range (high 90's and usually nails) I've dug many larger pieces such as iron globs or bolts that are IDing in 84-86 right in the IHP range. I had one target I swore was going to be a good deep target. Solid 84-86 until I got it out of the hole and it was a 2 inch long bolt. So one trick I've done is make a program called Iron, left everything the same as (Deep HC or Park are the 2 I prefer) except drop the disc down to -6.4 and raise the tones to 4 so it's still essentially 3 tones. So the first tone is lost, tone break 2 I run up to 30 at 100 Hz, tone break 3 I run up to 82 at 500 Hz and everything above 82 is at 901 Hz. This allows the iron grunt to really be heard on a deep iron target. If you don't do that the disc cuts the iron grunt out for the most part and the high tones come through. You can turn your iron volume up on the stock programs. But I'm finding it's still no the same. I don't hunt a park like that because it drives you nuts. What I do is when I get a questionable target I check it with that program. Works for me, might not for others and this is for deep old coin hunting. I just let the nickels go with the Deus 2. The TID isn't compressed enough IMO and 90% of what comes up in the nickel range is turning out to be part of a pull tab. The Equinox is a nickel killer, solid 13 maybe an occasional 12 in multiple sweeps 90% of the time is a nickel.
