Any problems with the 11 inch DD coil on f-5 calling rusty bottle caps high coins vs the stock coil...any input appreciated...thanks, Dan

To answer my own question got some good info from forum members and seems like the 10 inch Epp. for general hunting and 11 inch DD for relic hunting as Epp. coil handles those nasty bottlecaps better and in relic situations better coverage, depth and little or none rusty bottlecaps to contend with....
Note: ways to tell those bottlecaps if you do some research as some prefer double D coils...
