My main problem when hunting is aluminum.
Can slaw, pull tabs, pieces of siding, partial pieces of cans, small pieces of flashing, bottle caps, small pieces of foil from bags, etc.
I like to detect with little or (mostly) no discrimination so I go in my backyard, lay out a variety of crap I picked up in the field with a few coins and a gold ring.
Then I try the 9" LF, 9" MF and 6" HF coils to see how each one reacts.
I have used the MF coil the longest so thats the one I understand the most.
Obviously the 6'HF DD has the best separation but I find TID and multi tone more jumpy on the bad stuff with the MF coil.
Still learning the 3kHz coil but it does seem possible to ID some pull tabs as pull tabs with it.
I can never give up on the gold ring hunting, one gold ring can be worth $200 in clad. I have found three this year along with about 40 pieces of alum. junk thinking it might be a ring.
Not to bad, 3 out of 43?!
Hopefully with each new outing and a lot more practice I will come closer to defeating (?) my most hated enemy aluminum.
Good Hunting

PS I'm starting to dislike beer drinkers more and more everyday, which is kind of funny because I've been known to have one or two on occasion. Beer can crap is everywhere!
