3 Day Open Water Course

Most visitors leave Oahu with a sunburn and a shave ice habit. If you want to leave with a scuba certification, Manny's Diving Adventures runs a 3 day open water course in Honolulu that fits a standard island trip without monopolizing your whole itinerary.

The three days don't have to run back-to-back, which is the part that actually matters for trip planning. You can slot the days around other activities on your itinerary, keeping your schedule flexible. When you book, you choose your Day 1 date on the calendar, then on the next screen you type in the date of your second dive.

Structure-wise, Day 1 is confined water and dive theory - foundational skills that set you up for the open ocean. Days 2 and 3 each put you in open water for a 2-tank dive, building on what you practiced in confined water. All gear is included, so there's nothing to source or rent before your first session.

Pricing for this 3 day open water course Honolulu starts from $650 per person with gear included. For an Oahu activity budget, that's not a throwaway line item - but you're covering three days of instruction and two full days of ocean diving, not a single afternoon on a charter boat.

Cancellation terms are clean: 24 hours' notice gets you a full refund or credit. If Manny's Diving Adventures has to cancel for weather or other circumstances, same deal - full refund or credit. No-shows are charged in full, so if you're threading non-consecutive dates through a busy itinerary, make sure all your days are locked in before you confirm.

For anyone who wants more than beach photos to show for an Oahu trip, this 3 day open water course is a genuinely practical way to fly home certified.
