    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.

    Kapolei Aquatics Center is a hidden gem for scuba gear and swim lessons. Our 5 year old daughter…read morewas extremely nervous in the water and we signed her up for weekly lessons here. Now, only 4 classes in --- I cannot believe how much she has learned and how confident she is. We have met 3 of the instructors and they are amazing. Very professional but also great with children. NOTE: We have also taken lessons with the YMCA and Leihi Swim School - and while similar in pricing and length of time, Kapolei Aquatics Center is by far the best. They will not exceed 4 children per instructor and they are extremely flexible in available times for classes. The class is a definite 30 minutes (not 25 with 5 minutes to switch classes). So far, because they are working on getting more clients, we have been lucky enough to have one on one sessions with the instructor. It's not just fun and games, but real survival skills. In the beginning class they have taught my daughter to swim straight to the wall when she jumps in, and how to float and glide, and hold her breath well. The owners said they also offer classes for adults. I think I may sign myself up too! :) Highly highly recommend!

    Kapolei Aquatic Center is newly opened and offers a whole lot!…read more A division of American Renaissance Academy, Kapolei Aquatic Center is more than a dive shop. Don't get me wrong, they have tons of dive gear and will help you find the right gear for what you do and will help you get the right fit, but they also have a huge retail space. It's not crowded and it's easy to see everything. It makes it super comfortable and easy to take your time. They also offer swimming lessons for the super young through adult. And if you want to take a dive class, they offer both technical and recreational classes. The pool is on site too. The parking lot is huge. GPS takes you to the wrong side of the building, so take the road down to Midway and turn from that side. Enter in the first entryway-the others are blocked off.

Diving with…read moreHawaii Adventure Diving on the North Shore is something truly special, and every single time I go, it exceeds my expectations. 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!!

The crew was very helpful and made sure we felt very safe to do it. We hung on to a rope connected to the boat and just went with the waves. We went out on a choppy morning, so the only downside was some got seasick from the waves. Im glad we didn't do the cage cause I imagine we be tossed around with the waves. Other than that, it was super awesome. Only 6 of us went out so it was a nice small group. The photographer was great (see photographs - cost extra for the photos), the gal who took us out was very directive and could read the sharks body vibe so she knew how to guide us. And thanks captain Ronnie for navigating the choppy ocean.

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.

    This was one of the most disappointing dive experiences I've ever had…read more We are relatively new divers and booked this trip looking for a fun, safe, and well-guided experience. What we got instead was poor dive management and a complete lack of professionalism. During the dive, I ran out of air, which is a serious and dangerous situation in scuba diving. The response from the guide was dismissive and poorly handled, which only made the situation worse. The most frustrating part of the entire experience was dealing with Gabe, the owner. He had absolutely no patience and was openly unprofessional, not just with us but in the way he interacted with others as well. There was no concern for how unsafe the situation was, no accountability, and no attempt to make things right. For an activity where safety, trust, and professionalism are critical, this operation fell short on every level. We paid nearly $700 and walked away feeling stressed, unsafe, and completely disappointed. I would strongly caution newer or less experienced divers before booking here. This is not the kind of environment where you feel supported or safe.

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!
