    Amazing. If you want an authentic, fun, and safe experience open water diving, Underwater Oahu is the way to go. We came out for an introductory dive. We did two different dives with Mike. The first was a wreckage, the second was a reef. Mike was professional and gave a brief over view of the equipment. He stayed by our sides the entire time and let us dive at our own pace. The dive was so much fun that we came back for our open ocean certification. We signed up and were assigned Bart as our Instructor! We spent the first lesson in his pool where he went over several different exercises. Then we did 2 walk in dives at Electric beach. The last day of the course we did two dives in open ocean. Bart was professional, knowledgable, and encouraging. He repeated exercises until my husband and I were comfortable with performing them. He took us through a cavern tunnel, and showed us octopuses, turtles, and various other marine life. I left his class feeling confident in my abilities as a diver and excited to continue my diving adventures! We saw something cool and new on all 6 dives, and we heard Whales while at electric beach then saw them the next day. Underwater Oahu is military friendly. All of their employees are professional and SME in Diving. It's an authentic diving experience.

    I cannot recommend this place more. Bart is really patient, responsible and knowledgeable. he taught us scuba diving and helped us to earn the open water certificate in a short time. I am extremely happy about this experience and it is really fun!

    My wife and I did our certification dives with Mike at Underwater Oahu. This dive shop had super friendly and knowledgeable staff who managed their operation with ease and fun. Also: Mike has an incredible eye for spotting wildlife. I'm not sure how he does it, but mid-conversation he'd point out turtles and dolphins from land with his peripheral vision. While diving, his aquaman instincts brought us to a reef shark, eels, lionfish, and an octopus. The dive sites we went to were varied and beautiful (2 reefs and a wreck). As luck would have it, our boat also ran into 2 monk seals swimming together, probably playing hanky panky, in Mike's words. Thanks Mike for seamless and fun first dives!

    These guys are a small operation. The gear is in good shape and their setup is great. The only downside about being a small operation is that you have to bring your own camera, no onboard photographer. Travis and Laci, our dive master and instructor respectively, were awesome. The boat was a small dive boat but fit the 13 of us very comfortably. I did two dives and the dive sites were very different. The first one we did was called airplane canyon, a private plane wreck about 90ft deep. The second dive was a shallow reef dice with a lot of fish, a shark and an octopus. Even if you've never done it before, I recommend it, they offer discover scuba experiences- you can go diving with an instructor even if you aren't certified. The shop is hidden away a bit, no signs for "Underwarer Oahu", but it's in the same building as the spinner cafe.

The crew consistently goes above and beyond to make the experience both fun and safe especially Ro, Stacey, Terry, and Ronnie. Their professionalism, energy, and genuine care make all the difference. You can tell they love what they do, and it shows in every detail of the dive. The optional photo package provided by Terry is worth every penny. I'm a certified diver and have had the opportunity to dive in several locations around the world, as well as with other companies on the North Shore, but none compare to this team. Hawaii Adventure Diving stands in a league of its own. This experience means the world to me. I travel to Hawaii every month for work, and I try to do this shark dive every time I'm here. That alone says everything. I won't be diving with any other shark diving companies on the North Shore, Hawaii Adventure Diving is simply the best!! The North Shore has been hit really hard recently with devastating flooding. Hawaii Adventure Diving's crew needs our support. Book your dive today!!

I contacted the concierge at our hotel for a recommendation for a scuba diving operation and they recommended Matt at Kraken Divers. I contacted Matt, he responded promptly and we scheduled two days of diving. He offered to supply all necessary equipment but I preferred to bring my own and he supplied tanks and weights. He is a consummate professional. I asked him to observe me and make sure that I made no mistakes, and he did. We did a one tank beach dive and a two tank boat dive. He gave terrific and thorough safety and site briefings on all three dives. I have no hesitation in giving him a five star recommendation. And, believe me, as a multi agency instructor myself, he skipped nothing. I would happily dive with him anytime.

    There are many options for shark diving on the North Shore…read more One Ocean Diving seems like they are committed to the shark conservation, research, and education. You sign up online. With the times, if there are not enough they will consolidate times. We were signed up for 10am but got moved to 8am. You meet at Haleiwa docks near the blue hut (see photo). They provide mask, snorkel, and fins. You should bring a rash guard or wetsuit. The ride out is about 15 mins and as is typical in Hawaii, water can be choppy so you might get a little seasick. They give you instructions on the boat. Once there you hang on to a rope on the side of the boat and they take you individually to dive down closer to the sharks. We got lucky because there were tiger sharks (see photos). The cost is about $150 person but I would recommend paying some additional money for the go pro. You really want some documentation of what you did and saw. It's $50 for 2 people. They also have $250 option for photos and go pro but I think the go pro was enough. The people were really good and it was a great experience for all of us. Strongly recommend.

    I genuinely hate having to write reviews like this (especially for small businesses that are doing…read moregreat work on shark education), but I have to share our experience. Who we are: Our family, two adults and two children (tween/early teen), did this shark dive in early August. We are all scuba certified, strong swimmers, and have snorkeled A LOT. Our daughter is VERY interested in marine science, and our son has always loved sharks, so we mostly did this for them (my husband and I have both previously dove with sharks). First, the pros: - Responsible shark diving. This was VERY important to us and One Ocean does it right in regards to respecting sharks, their home, and space. - Yes, we saw sharks! Not a lot - maybe 4 or 5 - but they are wild animals, this isn't a zoo, so we knew we may see 1 or 2, or we may see 20 - it's the nature of wildlife. We did the first tour of the day as well, but just wasn't our lucky day. - The photographer was wonderful & friendly and did his best to get shots. It was tough, because the sharks stayed quite deep, but he did what he could. He did capture a great shot of our daughter, and a decent one of our son, but did not get any of my husband or I, nor did he take many of just the sharks, which did surprise me. For the extra $250, I would still recommend it, as it's impossible to otherwise capture photos. Just know that you may not get photos of everyone in your group, or the sharks on their own. - Very safe! At no point did myself, husband, or children feel unsafe or in danger Now, the cons: - What really negatively impacted our tour was the boat captain. He was EXTREMELY rude and condescending. Twice, he made completely unacceptable and rude comments and it was very off-putting. When we arrived to the site, there were tiger sharks there, BUT the team had done NOTHING to prep everyone to jump right in the water. On the boat ride out was the time to have everyone get their masks and snorkels ready, fins on, etc. but they didn't. They waited until we got to the site and then were trying to rush everyone off the boat in case the sharks left the area. The issue with that is with children, nothing moves quickly. The boat captain said to the photographer, snarkily, loudly and right next to my children, husband and I "these are the slowest four people in the history of snorkeling". Never mind we actually WEREN'T slow - all of the gear was stored in underseat storage (at their direction) and needed to be pulled out and put on. Had that been done on the boat ride out, no one would have been rushed. But that comment was completely unprofessional and unacceptable. Our kids were shocked that someone would be that rude. Instead of doing his job and offering to help, he stood by and made snarky comments about how all of the guests were "so slow". Then when spraying the goggles with defog, he fully YELLED at our kids for rinsing them after he sprayed them. We have been diving and snorkeling for YEARS and we have ALWAYS rinsed our goggles after defogging. He made ANOTHER snarky comment to our CHILDREN "yeah, because YOU know what you're doing over ME" as we were getting into the water. I was disgusted at this point and we hadn't even gotten in the water yet. - EVERYTHING about the tour is VERY rushed. They were ~20 minutes late in arriving, which I'm sure contributed to the rush, but of all of the tours we did while in Hawaii (4 scuba diving excursions, 2 boat excursions, helicopter, snorkeling excursion, etc), this was the ONLY one that we all felt VERY rushed by. Their lack or organization and prep work became the customer's problem, which led to a negative experience. - You're only the water for about 20 minutes. Even though they say it will be 25-30, no one from our entire boat was in the water for more than 20 minutes total. I only know this because I was videoing with our GoPro the entire time we were in the water, turning it on when we entered the water and off when we exited. Again, this may have been because the crew was late in arriving, so we were late in departing, but regardless, important for people to know when they are booking that they will only have a total of ~20 minutes in the water. Also know that you are in open water and the day we went, the current was STRONG. You MUST be physically fit and a strong swimmer to do this activity. Two of the people on our boat could not even participate because they weren't physically fit enough - there should be disclaimers and warnings prior to booking, but I don't recall there being any. For the price, I probably wouldn't do it again. While I very much support shark education and conservation, they could definitely do a much better job of on-time departures, preparedness, and customer service.

    When it was time to upgrade my short fins and diving mask that I literally found on the beach -…read moreWestside Dive & Tackle was the spot I decided to go to. I walked into a few other surf and snorkel spots but they mostly carried short fins. I went with the Leaderfins which are the most affordable carbon fins. The fins do come separately from the foot pocket, so I also got their forza foot pockets. They do offer a service where they put together your fins and foot pockets but only certain people are trained on that, so I did have to pick it up just a few days later- and that service is $30. I also got a pair of diving socks to go with my fins. They have different sizes, thicknesses, and cuts (high vs low). I also got a new diving mask and snorkel. The best thing about going to a dive shop is the ability to try things on and Westside Dive has so many different options. Being able to put on the foot pockets with the diving socks or even just trying on a few different masks to find the one that best fits your face is why it's better to come in person than buying online. The service was also super friendly. I was making some big purchases, so I wanted to make sure that each component was exactly right and the staff here was helpful and overall super chill. We talked story for a bit, exchanged where we like to go diving and even some fish recipes. If you're looking for diving gear, support local and check out Westside Dive!
