I have some hours on the Deus 2 with 9" coil now and several good finds already but i have one concern. IT tends to false on nails, especially old rusty square nails alot. Although i have learned the tricks to "not" digging them about 70% of the time now, it just really takes alot of time to circle those targets and look and listen for clues of iron falsing. I generally use the Deus 2 in Fast, Deep HC or a custom coin program built off of Park....just depends on my hunting location. Just wondering if there is a certain adjustment to be made to make the Deus like rusty iron less...? These iron targets usually sound good initially with numbers reading from 78 to as high as 95. They just usually give themselves away as iron if you circle them and swipe from several directions the numbers will drop to single digits and give the iron grunt.... Any tips would be appreciated. Thanks!
