You'd better start living in the real world when you start talking about using any kind of explosive device in the water. Several reasons why not to even think about trying it; the DNR or whatever outfit controls your fisheries will not like it a bit, just like using dynamite for fishing. The Police can come down and get into your case if you have fireworks laws where you live. Third, blow up my $1,000.00 boat and I'd guarantee that you'd have a face full of me to deal with!
