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.
This was my second time diving with big kahuna and they are outstanding. They have a great scuba location (diving where sea turtles commonly hang out) and both times we have been literally swimming alongside turtles. We also saw an eagle ray and many fish. Overall an amazing experience. Greg and Marina are great and were extremely accommodating with us even though we accidentally booked the wrong dive they made it happen for us and were so kind. Marina made sure we were doing ok during the whole dive and made us feel very comfortable. She even took a bunch of go pro pictures/ videos for us to have to remember the dive all included in the price! Would highly recommend going with big kahuna over any other company they are the best of the best!
