Nathan has a wonderful character, does not take himself seriously and it is down to earth. I really enjoyed this wonderful conversation.

• ## Interconnected tissues in decompression model

Multi-Exponential washout models. How to measure risk? DCS risk is intrinsically probabilistic and, not deterministic, in other words, there is no mathematical critical point in which you “can or can’t” get DCS. The risk changes continuously and gradually with decompression stress. Deterministic models work with compartments and base the decompression on a leading compartment in…

• ## Problem reaching your valves and isolator on your twins/ doubles?

Do the following exercises to improve your movements and possible fix this issue. The world’s population is aging and becoming healthier; therefore, we see more elderly people doing more outdoor activities. Diving is no exception; much of the technical diving community has a middle-age demographic structure. Other factors that contribute to the age range in…

• ## Tech Deco

This is a good program with a subtle set of variables and characteristics. It’s well suitable for an Open Circuit Diver to use on the field for last minutes review and run different profiles. What is lack is an alternative windows to run second or third dives in the same day.

• ## Dive Computers:

– A beginner’s guide. What is underneath? Schematics of a Dive Computer Sensors/Clock → Storage Unit ↔ [Control Unit / Arithmetic and Logical Unit]CPU → Output [Display] A dive computer is a device that operated upon collected data, it is an electronic board which does arithmetic and logical operations accordingly with the programmed decompression algorithm…

• ## Ascent Rate: 60ft./min.?

Have you ever asked to your instructor how was calculated/ came-up-with the ascent rate of the tables or computer that you used? Do you think it reflects basic fact of human physiology? Well, the short answer is no. The selection was made by the USA NAVY based on a compromised between work and safety. At…

• ## Joints Mobility

Why does nobody teach mobility in scuba? As divers we use a lot of equipment and swim large distances underwater, plus need to handle situations like maneuvering the manifold, valves, cameras, etc. People tend to think that what they need is a lot of muscles, but divers forget about mobility. Joint Mobility refers to the…

• ## Understanding nucleation as a process and what divers can do to mitigate it.

Divers have a generalized concept that decompression bubbles form with ascent and reduced its sizes with a decrease in ambient pressure but this isn’t completely accurate, tiny microbubbles are already present prior depressurization. Which means that two factors should be present for the occurrence of DCS, micronuclei and supersaturation. Although our internal body have no…
