  • The DIR Philosophy
    7KH',53KLORVRSK\ By Jarrod Jablonski A good SCUBA equipment configuration needs to support all of your diving whether that be an open water dive or a penetration dive inside a wreck or a multi-stage cave dive. The configuration must be able to adapt in such a fashion that the addition of items necessary for each dive does not in any way interfere with or change the core aspects. Diving with the same basic configuration allows the same response to emergency at all times while reducing task-loading due to familiarity . In other words, a good gear configuration not only helps solve problems, it prevents them. By achieving a configuration which is streamlined and comfortable to dive with, you will experience diving with reduction in stress and task-loading thus increasing your enjoyment. Strive to achieve a attitude where you NEVER accept any equipment situation where your own standards are compromised. Correct any equipment configuration problems immediately as opposed to waiting until the next dive. Few aspects of cave diving engender biased convictions like the topic of equipment configuration. Different people diving in different environments often reach very different conclusions. This tremendous diversity often surprises the new cave diver who usually expects that there will be a consensus among the "professionals." In fact, this diversity has been known to initiate rather energetic disagreements and while cave diving has undergone some significant changes during the last roughly 50 years of its evolution, few aspects of the sport remain more hotly contested than gear configuration. Perhaps because one's equipment is often a rather personal choice and people are prone to take offense when their decisions are challenged.

  • Doing It Right
    Doing It Right: The Fundamentals of Better Diving Doing It Right: The Fundamentals This book was written for anyone who wants to get the most out of their diving. From augmenting dive safety to increasing the enjoyment of your family’s Caribbean diving trip or planning deep cave exploration, DIR diving is the new foundation for all diving practices. This book outlines not only the essential skills and techniques constituting sound diving practice but also the central elements of a holistic approach to diving. “Jarrod Jablonski’s “Doing It Right” is an outstanding text on equipment configuration, bridging the gap between sound conventional diving and technical diving within all environments.” Tim O’Leary, Bruce Wienke NAUI Technical Training Operations “Now there is one great starting place for the information, skills and methods that, when used as intended, should not only eliminate the ‘accidents’ in diving, but should make anyone’s diving more successful and above all Doing It Right: more enjoyable.” George Irvine, Project Director The Fundamentals of Better Diving Woodville Karst Plain Project Jarrod Jablonski “DIR has taken volumes of SCUBA principles and improved upon them. At the core of DIR and GUE methodologies is the discriminating diver– a person who has a clear perspective on his or her role in dive exploration, and one who will eagerly embrace sound diving practices.” Tec Clark, Associate Director YMCA SCUBA Program Global Underwater Explorers Jarrod Jablonski is the president/founder of Global Underwater Explorers and the CEO of Halcyon and Extreme Exposure diving equip- ment. Actively involved in dive research, education, and underwater motion picture production, his exploration work includes dives to nearly four miles from the nearest air source (19,000 feet) at a depth of 300 feet, resulting in several world record accom- plishments.

  • ADM Issue 4 Finnished
    DEMA 2000 marks one year since the sale of DeepTech by my two ex-business partners. Being the original founder of DeepTech, the news of its sale without my knowledge or approval kinda, well lets say: rubbed me the wrong way. Not only was I concerned about all the years and thousands of hours of work I put into DeepTech but also about the subscribers who had paid their money for a subscription and now would not receive what they shelled out their hard earned cash for. My reputation not only as a publisher but also as a respected diver was immediately at stake. Knocked back to step one after all these years was a hard blow but also a blessing in disguise. When I started DeepTech I had no connections, no advertisers and very little money. After 4 years in circulation I had thousands of connections, good rapport with my advertisers, and a little more money to start over from square one. Advanced Diver Magazine was born with no business part- ners, many of the same advertisers and a data base of good subscribers available. One year has passed and the small staff at ADM has delivered what we had prom- ised. An on-time, high quality, fully illustrated dive magazine like no other. Designed with a good balance of text, illustrations, photos and less than 20% advertising. ADM will continue into the new millen- nium providing what we promised our subscribers with the quality and graphic design that I expect as the founder and publisher. After all, my reputation is at stake.

  • Rebreathers for Cave Diving
    technical The use of rebreathers in caves is nothing matters new. Decades ago, Hans and Lotte Hass used them to venture into marine caves. Profiles like Rob Palmer in the UK, Bill Stone, George Irvine and Jarrod Jablonski in the USA, or Olivier Isler in Europe, are also strongly linked to rebreathers and cave diving. Recreational cave divers discovered Oxygen CCR in the Navy sur- plus, then experimented with Draeger Dolphins, and more recently, APD Inspiration. Nowadays, there are many different brands and models, and they become even more popular within the cave diving community worldwide.
