lobster men with shotguns? Are you serious!
Where do you buy a measuring gauge and tickle stick and catch bag?
It may be rumors and stories, but I have heard of divers surfacing to some unhappy looking dudes with guns. Also, I have read newspaper accounts of lobster fisherman who have shot at each other for raiding each others pots. I have no doubt if these same goons thought you were raiding their's they would open fire right on you.
edit- that is not to say all lobstermen are goons, just the ones that shoot at each other...
Gauges and bags you get at your LDS. A tickle stick you can make. But really, if you don't have the stones to pull em out of their holes with your hands, you don't get any

BTW sticks are illegal in some areas, so make sure you know the laws in both the waters you dive as well as dock in.
