Just like fishing, there is allot of skill involved, being at the right place, right tide, right bait/lure, then more skill involved with fighting fish, landing/net/gaff. But you know, there is also allot of luck involved. Your skill level is way up there, I know how many hours you have spent, not only researching sites but many ,many hours researching machines/programs.
Still, you are the luckiest guy I ever met, especially in metal detecting. Some people have made consistent good finds, where you have made consistent great/banner finds. Its not a bad thing, don't take it the wrong way, your the luckiest metal detectorist I know.
