Get Andy's book, you will understand what to do and why!

My first time relic hunting using Andy's program, I hit some 16" Minnie balls in good ground. The few changes he suggests transform the Deus. Until I used one set up right I was unimpressed, glad I gave it another try, now it's my favorite detector since the Mark One in the 80s and I had them all, LOL
The other day I took my Nautilus 2ba with 15" coil for a spin and missed my Deus, it goes deeper than that setup, never thought I would ever say that
