I did not get the HF coil. Just the standard 9" coil. So far it's been very frustrating! It's the hardest machine to decipher what it's telling me I've ever used.
I hunt places mixed with iron and non-ferrous trash a lot. I'm totally lost figuring out what's what with the Deus. I can pull out the Equinox in the same places Park2, 5 tones, 0 iron bias, recovery 5-6, Horse shoe engaged, and never have an issue finding coins and telling trash from good targets. Unless I'm trying for nickels I dig very little trash.
In my yard on buried coins the Deus is no problem and it's deep. This detector is going to take some time to get used to.
