    Greg stands out as the star of this operation, earning consistent praise as a patient, knowledgeable instructor who excels at making nervous first-timers feel completely at ease. Reviewers highlight how he balances thorough safety training with fun, gives individual attention even to larger groups, and has a genuine passion for sharing underwater experiences. His team members, including Jen, Dray, Tony, and Captain Joe, also receive specific kudos for their teaching abilities and attentiveness. The setup works particularly well for beginners and families. Multiple groups mention bringing kids as young as 11, and parents appreciate the intimate boat size that doesn't feel chaotic or overcrowded. The Hawaii Kai location offers convenient free parking and nearby restaurants, plus relatively short trips to quality dive sites where guests regularly spot turtles, octopus, sharks, and abundant marine life. The photo packages are mentioned as worthwhile additions, capturing memories without you having to worry about equipment. Several reviewers specifically note this is their new benchmark for dive operations and have returned for repeat visits.

    Wow! Second visit to Oahu and second time diving with Big Kahuna! My party of five divers had THE BEST time! Our dive crew consisted of Greg, Greg (2.0) and Alan. They were super friendly, helpful, and encouraging. We dove earlier in the week with another company. While we had an okay time, it was a large and impersonal experience. I disliked it so much that I considered not continuing on my journey to become a certified diver. However, after diving with this team, I’m hooked. Thank you, fellas, for an amazing experience. We will sing your praises to everyone we chat with concerning diving on Oahu. Much Aloha from your Wyoming Ohana. The Yeltons and Dearcorns
