What is Free Phase RGBM?

From our Development Partners at Free Phase Diving - Free Phase RGBM for the XEO is an implementation of Dr. Bruce Wienke’s ground breaking decompression model for both recreational and technical divers.

Why do I need RGBM?

If you have ever felt tired or fatigued after a long dive? This is a common complaint from divers using a traditional “dissolved gas” model. This is typically the result of an incorrect decompression.

Traditional models only deal with dissolved gas in your tissues. But there are two types of gas in your body: dissolved gas and free gas. Free gas, or micro bubbles, can grow and multiply on ascent and if not managed and accounted for can cause DCS problems. In simple cases this is the fatigue you feel after a dive; in more serious cases actual DCS.

RGBM manages both dissolved gas and free gas in the tissues and blood of a diver. It uses a balanced approach to create an ascent plan using deep stops to control bubble formation and growth by using pressure to “squeeze” gas out of bubbles while also managing the build up and elimination of dissolved gas.

The result is a decompression schedule that starts deco deeper and gets you out of the water faster leaving you feeling better after your dive.

For recreational divers RGBM requires deep stops even on “no stop” dives and applies additional levels of conservatism to your no stop limits when you are diving multiple time per day, diving with short surface intervals, diving over multiple days, diving reverse profiles, working hard, diving in cold water, or ascending/descending more rapidly than recommended.

RGBM applies a dual-phase approach to decompressing divers and is well suited for:

  • Multi-day, multi-level diving
  • No-stop diving
  • Decompression diving
  • Mixed gas diving
  • Saturation diving
  • Altitude diving
RGBM more accurately predicts what is happening in a diver’s body and as a result creates a more effective decompression schedule.

Does RGBM work?

Yes it does! Developed by Dr. Bruce Wienke at Los Alamos National Laboratories RGBM is the result of years of development and refinement. Recreational and technical divers from multiple agencies have tested it extensively over the past 14 years including NAUI, ANDI, and others.

The RGBM Data Bank at Los Alamos contains the results of thousands of dives under a variety of conditions that illustrate the safety of RGBM. NAUI Technical Diving has been using RGBM since 1998 logging some estimated 25,000 dives on mixed gases down to 300 feet.

Here is what people are saying about Free Phase RGBM:
"Finally a dive computer that tracks nicely to the RGBM tables, intuitive to operate and easy to read in low light. As a tech diver I have been waiting for this hardware/software combination to come along and look forward to more leading edge products from Free Phase and Liquivision."
-Jeff Grezeszak, NAUI Instructor, Trimix Diver

"This version new version of RGBM runs with superb efficiency, has proven itself to me through extensive, rigorous testing in numerous varied environments and has convinced me to make it my primary method of ensuring my safety."
- Raymon W. Bacchus, NAUI & SDI Instructor Trainer, Trimix Diver

How can I get Free Phase RGBM for my XEO?

Free Phase RGBM for the XEO includes the full iterative RGBM model, used under license from Dr. Wienke, and includes all current XEO functionality plus the RGBM algorithm for both open circuit and close circuit rebreather divers (Liquivision CCR PIN code is a separate purchase).
