I have to say that the people at this store are the friendliest and most supportive people that I have run across in my scuba adventures. Although I've lived or worked near the store for years, I never realized they were there (its right on Greenville, just South of Northwest Highway). The store is well stocked and they are more than happy to share their knowledge with you. No high pressure sales here! Drop in and take a look around; I don't think you'll be disappointed.This store also has a good (and always changing) selection of used equipment. They do certification courses (the prices are extremely reasonable and are in fact less than what I paid) and they even have a $35 intro course where you can get into the pool with the scuba equipment to see if its for you. If you thensign up for their open water course, you get $25 off. I'm looking forward to meeting other Dallas divers through their happy hours and on one of their dive trips.
