20-22 April, 2023 Valletta, Malta

Greetings Researchers and Diving Professionals,

We are pleased to announce that we will be holding Rebreather Forum 4 (RF4), Thursday through Saturday, 20-22 April 2023 at the old University of Malta campus in Valletta, Malta, sponsored by DAN Europe, DAN, PADI and Heritage Malta. The purpose of the scientific and trade-only meeting is to advance the diving community’s state of knowledge regarding rebreather technology and its uses, with the goal of improving rebreather diving safety and performance. 

We plan to hold a Non-Caustic Cocktail Reception on Wednesday evening before the conference, a Friday bag lunch, and a Saturday evening banquet with guest speaker. In addition, we will have an exhibit area for participating vendors to display their equipment, near to the main conference room. Vendors interested in sponsorship opportunitiesexhibit space and or conducting demos, please contact the organizer/convenor (see below).

Who Should Attend?

We are expecting several hundred attendees representing technical diving equipment manufacturers, training agency personnel, instructors and instructor trainers, diving and hyperbaric medicine researchers, scientific and military diving personnel, government health and safety officials, and other organizations involved in rebreather diving. The meeting is not intended for diving consumers. If you are professionally involved in rebreather diving, we encourage you to attend. There will be a limited number of tickets available.

The RF4 Program and Proceedings

The RF4 scientific program committee consists of Drs. John Clarke, Simon Mitchell, Neal Pollock, Frauke Tillmans, and journalist Michael Menduno. The four primary focal areas are diver safety and culture, physiology, technology, and training. Proceedings of the meeting will be published and made publicly available.

The original Rebreather Forum was held in May1994 in Key West, FL.; Rebreather Forum 2 took place September 1996 in Redondo Beach, CA. Rebreather Forum 3 happened in May 2012 in Orlando, FL. A related event, Rebreathers and Scientific Diving workshop took place in February, 2015, on Catalina Island, CA. Click the links to download the relevant proceedings.

Shipwreck Diving & More

Malta is surrounded by hundreds of historical shipwrecks, including nearly 20 archaeologically-significant wrecks under the management of Heritage Malta. With their support, the three-day program will be augmented with organized diving on various historical wrecks in Malta the week immediately preceding the meeting (April 12-19) and additional shipwreck diving in Gozo the week after (April 23-30). This will include the exclusive opportunity for RF4 attendees to dive the wrecks in Malta’s newly launched deep water archaeological park. Diving activities will be coordinated by RAID, Heritage Malta and their registered dive centres. In addition, there will be workshops, and demonstrations held prior to the meeting.
