Ever wondered how we learn and how we retain what we learned? Have you noticed that you will retain less than 100% of the material presented? Furthermore, because you zone out, get distracted, or do not comprehend, you are not even cognizant of the things you see and hear during the class. Every time a,
During a dive, clipping gear to D-rings provides easy access to items we use most often. Reels, lights, primary SMB’s and line arrows are good examples of items we use often on a dive.
However, we bring some items “just in case”. Many of these items could present an entanglement issue if stored externally. Pockets are often the best place to store these items.
For example, spare masks, gloves, secondary cutting
Staying warm during the dive is not just a matter of comfort. As we have learned from the 2007 NEDU study, it also affects our decompression and, subsequently, our DCS risk. Supplemental insulation provided by dry and wet suits will shift the Lower Critical Temperature (which is the ambient temperature at which heat production responses are initiated) to lower values and thus, delays the onset of core cooling as water tempera
Although alluded to in your initial rebreather training, the idea of ‘optimal loop volume’ escapes some divers. Even among advanced rebreather divers, the loop appears to be managing them instead of them managing their loop. They learned to cope, instead of, to control it.
