Check in at 8:30 AM for morning departures and 1:30 PM for afternoon departures for the mandatory boat safety briefing.
If you miss the check-in time, you must reschedule and a $50 rescheduling fee per person applies.
Bring your certification card (digital or physical), a swimsuit (not provided), a towel, sunscreen, and water. You can also bring snacks as needed, and you’re encouraged to bring a reusable water bottle.
The crew here consistently earns praise for creating a welcoming, professional atmosphere on the water. Guides like Zoe, Daniel, Sam, and Swayze get frequent shoutouts for their knowledge and attentiveness, while Captain Justin and Derek keep things running smoothly. Divers regularly spot octopus, sea turtles, eagle rays, eels, and sharks at sites including the popular Sea Tiger wreck. The team handles everything from discovery dives to advanced certifications, and several reviewers mentioned helpful touches like motion sickness support and optional GoPro photo services that let you focus on the experience rather than documenting it. A couple of concerns surfaced in recent feedback. One reviewer noted frustration with feeling ignored during briefings and questioned some wildlife handling practices by a staff member. Another diver found three trips to the same site repetitive and had issues with boat positioning after a dive. These seem like isolated incidents rather than patterns, but they're worth noting. Overall though, the operation has built a strong reputation with repeat customers who come back specifically for this crew whenever they're in Hawaii.
Has a great 2-dive trip with Derek and Sam. We saw a huge green sea turtle, lots of eels, some octopus, parrot fish, trumpet fish, and got long fives as it was just 2 of us plus guide in the water. Ask in advance for kama’aina discount. Gift shop gave us 20% off as well. Great people. Great experience.
