After spending two half-days with Nick at East Coast Divers, I walked away with a completely new…read morelevel of information and confidence. Even though this wasn't a certification course, the workshop provided practical setup advice and technical insights that are hard to find elsewhere.   Nick's technical knowledge is expansive; he was able to address every question or concern the group had with ease. What impressed me most was his willingness to help outside the specific scope of the workshop--if we had a scuba-related subject we were curious about, he would work with us one-on-one to provide pointers or recommendations. It shows he's invested in the diver's overall success, not just checking boxes for the day's lesson.   He clearly cares about the curriculum and his students. He went over the allotted time both days to ensure we truly understood the material, and I wouldn't have shortened it by a single minute. If you are looking to fine-tune and improve your in-water skills, I highly recommend his Advanced Buoyancy, Movement, and Positioning Techniques workshop.

My first dive with Jim and the Boston Scuba team and I could not be more impressed with the venue…read more(cool area of Boston) the professionalism (low key confidence and super organized) and the dive boat is roomy and made to handle the harbor (12 tons of stability). Jim has a great play list during the dives and knows the water cold (yeah 50 degree at 50 feet so bring all of your 7MM gear) and where the fun stuff is. Lots of stuff to see on the ride as well between CodZilla and the pleasure crafts in the harbor. Sipped a couple of cold ones at the East Coast Cider outside lounge afterward...all in all a great day!

I've been a customer of Atlantic Aquasport for over 20 years, and without a doubt, they are one of…read moremy favorite small businesses to support! My husband and I got our Open Water Certifications from them years ago (their on-site pool makes classes so convenient!), and more recently, our 12yo son completed his certification with Don and team. The instruction is top notch. All of the classes were 1:1 and tailored specifically to our needs and comfort level. We all came away incredibly confident divers, which is the best measure of success. Anytime we're on a trip, the dive master always comments on what a skilled diver my 12yo son is. I swell with pride every time I hear this and am so thankful for the great instruction he received, as it will help keep him safe in the water for years and years to come. As an added bonus, Don lets my son borrow equipment anytime we go away to ensure he's using the same equipment he trained in and therefore as comfortable & confident as possible. As soon as my son stops growing :-) we will buy our gear from Atlantic Aquasport. But until then, being able to borrow equipment has been a huge cost saver and convenience. My husband and I have purchased all of our gear from Don and couldn't be happier with the quality, selection, and support we get even after the sale. My regulator has a lifetime guarantee from Don. It had a problem Don couldn't fix (likely from years of being jostled around by baggage handlers across many airports) and Don replaced it free of charge, no questions asked. My most recent experience with Atlantic Aquasport was going on a Saturday morning dive with them to Nubble Point. Despite having logged 500+ dives, this was my first New England dive and I loved it! The crew let me borrow additional gear to ensure I'd be warm enough, conducted a thorough safety briefing, and guided me on a really fun dive that surpassed my expectations for what I'd see in New England waters. I love the Atlantic Aquasport team and can't recommend them enough for training, gear, and local dives!

I drove past two dive shops today thinking I'll wait to purchase my new gear local. I have waited all week thinking on my day off I would be all set. I checked store hours. I double checked before I left. I drive all the way to Weymouth from Nashua and I get to the dive shop at 10:30. As I pull up the place looks abandoned. Pit in my stomach I get out of my car and a poodle meets me at the locked door. The place was closed. Sign on door says. On a swimming trip. Amazing. Last time I pull into that parking lot.

The classes were taught very well- they were VERY thorough, and extremely reasonable. We've now been divers for a couple years, and every time we come in the shop, they are so friendly and helpful for anything we need! Once you've gone there, it's like you're family. Items are always always in stock. I think maybe ONCE they didn't have a certain bag in, and he ordered it right away for us. Prices are great- comparable to what you can find on ebay, and we would rather buy from them anyway because of the safety factor. We will definitely continue to go here- it's a great local shop that offers charters, advice, and continuing education. I think my husband would live there if he could!

I recently completed my open water SSI certification with Dave at Aquatic Specialties and had an…read moreincredible experience. I was completing this course, including the open water portion, all in December; I was eager to get certified in a New England winter, and Dave matched that energy. From the moment you meet Dave, his enthusiasm for SCUBA is palpable. Throughout long class days, Dave is cracking jokes, telling anecdotes and getting you excited about the skill you're about to have, all while answering a barrage of questions. In the water, he is professional, vigilant, and in his element. He exudes an air of calm and control, allowing you to confidently perform skills that would otherwise be terrifying or disorienting- like removing your goggles or respirator in 45 degree water. Beyond that, the staff is equally as knowledgeable and the community they foster is incredibly warm and welcoming. Even on my open water dives where I thought it was just going to be myself and Dave, I ended up meeting more people who tagged along just because they wanted to dive. I'd be hard pressed to find a more inviting community that is excited to pass the knowledge along to others. What an awesome experience and an awesome group of people that I can happily say I'm a part of now. Thank you Dave! 5/5 stars
