If you are just sailing along and not on a Cousteau expedition or =
anything, why would you care what the depth was beyond 500 feet? It's =
not like if you dropped anything OB you could retrieve it from that =
depth, or that you'd actually want to visit with any of the denizens who =
live there. It's not like you'd actually have a keel that would bong on =
anything that deep. As long as your depth sounder was working well so =
that when you got less than 500 feet it would start working again, =
wouldn't that be sufficient? Maybe you could jury rig the thing so that =
an alarm would go off when you hit 500 feet again...heaven help you =
would not want to miss going into the shallows like that. Or maybe you =
like anchoring at the depth? You must have an awfully big anchor locker =
to hold that much chain and rode. Don't you get tired hauling it all =
back up again? And aren't you afraid that the swing on the rode will =
put you into the shipping lanes? Good Gadfry, I;ve turned into =
Gilligan....
