Highlights
Outing Highlights
Custom Hawaiian Radons and Six‑Pack Service
Fathom Five operates custom‑built Radon boats made in Hawaii and is the only six‑passenger (6‑pack) diving operation in Kauai—allowing close attention from crew and small, consistent groups.
Twenty Local Sites, Two Distinct Dives
Divers choose from 20 frequent sites located only 3–5 minutes from the boat harbor; the first dive typically ranges 65–95 feet and the second 30–60 feet, delivered as a two‑tank itinerary.
Separate, Skill‑Matched Groups and Refresher Options
Groups are not mixed—certified divers dive only with other certified divers—and with two boats the operator can cater separately to advanced divers and those who are rusty (with a refresher option available).
