Hawaiian Diving Adventures has you covered. We provide high quality compressed air and EANx (up to 40%) for scuba cylinder fills for a number of dive operations on Oahu, as well as the University of Hawaii. We also offer Hydrostatic testing and VIP services, as well as cylinder rentals for scuba dive professionals and scuba dive operations in Honolulu.

You can schedule an appointment to pickup at the Hawaiian Diving Adventures shop, or have us deliver to Kewalo Basin Harbor. We deliver full tanks and pickup empty tanks up to three times each day at Kewalo Basin Harbor. We can deliver to any boat in the harbor. Additional delivery locations and times may be available.

Our truck is at Kewalo Basin Harbor for delivery/pickup from 7-7:30am, from 10-10:30am, and from 2-2:30pm (pickup only).

Tanks can be ordered online. We accept online orders up until 5:30am the day of delivery. If your needs change, you can call us and we will do our best to accommodate you.

All scuba cylinders can only be delivered to certified and insured dive professionals or companies. Instructors or dive shops will be required to provide a copy of scuba instructor and nitrox qualifications, as well as current professional liability insurance.

Nitrox analyzer rental is available for an additional charge.

Cylinder rentals must be used for day charters. The rental period is for the duration of the trip, and pickup times are firm. There is no refund for unused cylinders.
