Aqua diving academy is a shop tucked off of commercial street in Portland with a smaller sized parking lot in front of the shop that is free (though plenty of parking on street). It looks small on the outside so I wasn't sure what to expect, but I tell ya this shop has TONS of awesome gear for its size! I needed a snorkel and new mask, with an older one and old fins I brought in to have them look at for an upcoming trip to Tahiti and found many to try on and compare. The sales person I had was great- he was patient, helped me analyze my fit and things to pay attention to and tricks to get a good seal for a good mask fit and pros/cons of different types. He also looked at the well used older fins I brought in and rather than say they looked like the needed to be replaced as I had thought, inspected them for dry rot etc to make sure the condition looked ok and said as long as I'm comfortable in them they should be fine rather than buying new. He looked at my snorkel and could see one of the seals was no longer working. I looked at new fins too just in case I needed a back up. Good selection of reef safe sunscreens and other accessories like waterproof bags, etc. I was most surprised by how many wetsuit options (full,shorty, etc) they offered, including thermal tops and bottoms,many of which could be also used for surfing and other sports and many were not highly priced like i thought I'd find at a dive shop. Obviously if you are a diver they have quite a bit of dive gear and I believe they offer education/pool/diver certification through them as well. Loved my mask and snorkel on the trip I took, snorkeling multiple times per day it was a major step up in performance and comfort from my US divers inexpensive one prior. All in all highly recommend this shop! read more
