Nowadays, more and more recreational divers are coming into contact with technical rebreather divers, perhaps even being buddied up with one on a dive. What follows are some good things for open circuit divers to know about closed circuit rebreathers. Michael Rothschild gives us a quick glimpse into rebreather diving and what one can expect when diving in a mixed team.

Survey for instructors

Scubanomics is conducting research into the 'economics' of being a dive instructor. They are therefore asking active and non-active dive instructors - scuba diving and freediving instructors, instructor trainers, and course directors - to take part in a survey.

This should take approximately ten minutes to complete, and it is believed it is the first of its kind. 

The resulting data will be published, in order that the dive industry benefits from it.

The Fundamentals of Better Diving

Fri, 22/01/2021 - 23:02

One of the most influential texts in diving is entirely rewritten, detailing a new vision for scuba diving with a clearer picture of the theory and practices behind performance diving strategies that support safe, efficient, and fun scuba diving. The new edition is available in English, German, Italian, Spanish, Korean, and Chinese.

DCS Risk Factors

A recent big-data study performed by a DAN Europe research team used modern statistical analysis techniques to dig into a sample of nearly 40,000 open-circuit recreation dives and look for patterns and clues about DCS risk factors in real-world cases. Some of what they’ve found confirms our previous knowledge and opens entirely new avenues for research into the factors that contribute to DCS risk. Here’s what we’ve learned.

Divers Adrift - Surviving Being Lost at Sea

The more difficult a wreck is to get to, the more rewarding its discovery, but also the more likely it is that you’ll run into trouble during or after your dive. Challenges become hazards quickly, and many offshore adventures are rife with risk factors that make it more likely that you’ll surface from your dive without a boat in sight.

Whether your charter sprung a leak and became a new dive site or drifted off in search of another diver here’s what you need to know to survive.

Gas Management 101

Checking your air a few times during a dive and coming up as the gauge nears zero is not dive planning. Before you hit the water this summer, brush up on the basics of gas management — this will help keep you safe and might even extend your bottom time.

Neurological DCS for Divers

Whether you have the skills and training to care for a diver yourself or you want to be prepared to help until a more experienced caregiver is available, learn the basics of assessing post-dive symptoms.

Articles like this one are no replacement for training, but they are a good way to refresh or build your awareness of the importance of emergency-response skills.

Rising to the Occasion — Ascent Rates for Experienced Divers

Almost all experts in dive medicine agree that divers should ascend slowly following dives, whether they’re recreational, working or technical. The reality is that very little direct evidence exists about what ascent rate is safest. Most of the recommendations come from observational studies of bubble grade found using Doppler ultrasound or are based on anecdotal or theoretical concerns.
