this is a great diving shop. they have huge selection of equipment, include books. they are official dealers of scuba pro, and make repairs too. they provide all levels of diving classes but the tech diving is not that trendy there. i guesse not so many New Yorkers dive tech, they mostly do recreational diving over vacations. pan aqua offers diving trip to many distenation with in central america and the carribiane. this top diving center is locate on the same block with NY sport and tennis and they do have alot of lockal customers, thats way they are not cheap. did i say cheap? this place is pretty expensive.
