Default Re: Fishfinder/GPS question?????

Hammer, for your purposes (diving) there is no machine that will work with both numbers accurately. They don't have a mathmatical algorithm that can change from td's to l/l's in an accurate fashion. Having said that, if you use a GPS that displays td's to mark a spot, you can return to that spot in td's.

Bottom line is, if you've got wreck #'s in TD's, you'll probably only find them with a Loran unit.
