Loran instructions

[sharkboy]

I've got a II Morrow Tigershark Loran that I use as a backup in case my GPS craps out. It also has a few numbers in it that was left by its previous owner. I can use it well enough to get home if I need to, but I don't even know what most of the buttons do. Does anybody know where I can get a manual for this thing? I haven't been able to find one on the net. If anybody has one I would sure appreciate a copy.
