Underwater Oahu

Mike with underwater Oahu was great to dive with. My two daughters, aged 11 and 10 did their open water dives with him to complete their open water certification. He was so good with them and clearly understands how to work with kids. He was safe and an excellent teacher. He taught me a few things too. The equipment is clean and very functional. we had no issues. He is very prepared. He’s got a good sense of humor and showed us some fun things at Electric Beach. I will definitely dive with Underwater Oahu again next time we’re there

Michael was amazing! We were in town and only had one day to dive. We rented tanks and he gave us all of the beta needed for a shore dive on E Beach. We highly recommend you visit this shop if you are in the area!

Had a great time with underwater Oahu!
Good gear, fun and competent crew!
I felt very safe and they took us to two great dive locations.
I highly recommend! Next time I am in Oahu I will dive with this outfit.
Also there are great beached near the marina, where they are based that are quiet and not crowded. Good break from the crowds of Waikiki and the North shore.
Also check out the “beach house 604” for a good bite to eat and a cold one after the dive👍🍻

My husband and I scheduled with Underwater Oahu for our first scuba experience and also first trip to Hawaii. Being a small company attracted us because we weren't eager to "jump in" with a large group of first-timers. Mike explained the basics well and took us out on the boat and we practiced skills just below the surface before descending the line to catch a glimpse of beautiful coral, a couple of sea turtles, an octopus and many tropical fish. We visited 2 separate dive sites during our 90 minutes.

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.
