I'm still fairly new to using the Exp II and have thoroughly read the manual and Andys Etrac/Exp book but cannot find any info on hunting in iron mask mode vs. the basic coin pattern. I have really only used the coin pattern since I got the machine. I mainly coin hunt. I have yet to dig a piece of iron. So far with the testing and hunting I have done, all coins and silver will ID somewhere in the non-disc'd area of the coin pattern. (DUH! ) I know allot of the pro's use iron mask. I also know that depth can throw off ID. Today I did mess around with Iron mask on a hunt and got an ear full. I heard allot of good sounding tones, but the cursor was everywhere but where I like it to be on the smartfind screen, (upper right corner). So I guess my question(s) are: Is iron mask just less discrimination than the coin pattern? Is there an advantage to hunting in iron mask for deep coins vs. the basic coin pattern? Do deep targets (coins, silver) ID on the smartfind screen in the darkened area of the basic coin pattern (nulled) whereas they would have been heard and seen in iron mask mode? Thank you for any and all help and feedback on this. JJ
