Divers, stay away from this shop!
I signed up to do Advanced Open Water certification with this shop and had a horrible experience.
First, they don't offer knowledge reviews for AOW training (I got the book from them, not e-learning). I was simply given the book and asked to read it.
Second, the shop is run in a way that dive masters for each dive are not even informed that they are taking on an AOW student and which specialty adventure dive the student is doing. They did not assign the same instructor for the students and my dive log was not even filled if I didn't ask for it. My first two dives were with a good and responsible instructor (Jared) but I had to tell him I was doing the course, clearly the shop did not. On my third dive (navigational, a required dive to complete the certification), the instructor taught me nothing (no underwater exercise) and I did not even see a compass. I also felt unsafe about how the dive was run.
When I communicated with the owner, Nick, he was neither polite or apologetic. I paid for a 6 dives package to complete my certification course and I asked for a refund for 4 dives (as my third dive was a complete waste towards my certification). He refused and accused me of showing up at the shop without reading the book, which I did. During my interactions with the shop, I was never once asked to go over the exercise in the book nor given a classroom session.
Also, one local diver on the boat told me it's the most unprofessional dive shop on the island, he only did dives with them when all other shops were booked. Enough said there.
Go somewhere else, there are plenty of choices in Honolulu.
