New to wiscuba gps cordinates needed!!!

[Omicron]

A lot of the frequently dove wreck are already buoyed, so any GPS will get you close enough to the buoy to find the wreck.

The author Chris Kohl has an excellent book called The Great Lakes Diving Guide.  Use that as a reference to find out what you want to dive.  However - don't rely solely on the coordinates in his book.  Back them up by asking someone else/researching somewhere else to confirm his numbers.

A depth finder will help you get to wrecks that aren't buoyed.  Any ol' one will work (believe me...we've found wrecks on some pretty simple depth finders).

I'm sure lots of other people will chime in as well.
