My wife and I are visiting Northern MA at the end of July and are looking at diving in the area. We are experienced Dry Suit divers (own DUI), but have not dove the Atlantic at all. We've been down to 50 degrees. Hey we live in Texas, that's cold here. I grew up in Malden and sailed extensively around Rockport and Boston as a kid. I'd like to see what was underneath all those years. I'd be interested in Halfway Rock, Egg Rock and anything else of interest. We can shore dive or charter. We will have all gear except tanks and weights. We do love our Nitrox (Geezer Gas). Any suggestions? I am a PADI instructor and my wife is a Divemaster. I only mention it for skill and knowledge reference. Most of our diving has been blue water, but we teach in rock quarries year round and have a couple of hundred dives plus.
