OK,RC Detector its to muddy to dig then just Flag it. Now for idea number 2 , dk dogs, I looked you up and found out who you are, what type of work you do and who you work for. Now tell me once again why you can't hunt? A man with your connections there is no excuse. If they can find a metal object in a child those same connections that you have can find one in a plug. Now for not being able to dig, your co-workers have chain saws to cut through Ice to save someone. Once again they can cut your plugs for you and they would be very easy to drop back into the holes. Just remind them what you do for a living and they should think about it because if they ever need your services you could just be out trying to metal detect the hard way and your just to busy or tired to help them when they ask for it. You have power your not even using. Just put the word on them and now you could use some of their help. Humor is better than crying in the mirror like I do everyday. PS I'm exactly twice your age and whem I was in USMC Viet Nam they called me beaucoup dien cai dau, pronounced BOO COO Dinky-dow .meaning much crazy in the head. I guess I still am.
