I agree Frog. IF you do a LOT of diving, right now id only recommend the ML..... UNLESS you do some additional sealing on the GG. Not because they are great...... but they do survive. The GGA..... those knobs WILL freeze up if you dont play with them ESPECIALLY if they get wet. The GG have improved 1000 percent over the first version. If you are strickly wading and want a pair that pretty water resistant...... GGA, harolds, or make your own peltors (ole beach nut has a Utube video).
