Deep Divers

Among the first things beginning divers learn is that gas consumption increases at depth. For example, a cylinder that would last a diver 50 minutes at the surface may only last ten minutes at 40 mi>. That’s not a lot of time when there is so much water over your head. Because of this significant increase in gas consumption, deep divers need to be able to determine, ahead od time, whether or not they will have suficient breathing gas. One way to do so is to employ many of the same dive planning techniques technical divers use, including determining SAC rates and projecting gas consumption on each segment of a multilevel deep more Getting Started In Cavern and Cave Diving http:node..1001> Your answer will help determine which of the many available avenues is best for you.

Whether you are a new or more experienced diver, the need to explore this new weight-less world can become overwhelming. Visiting the underwater world can be a sensory overload of things to see and explore. We first start out observing fish, plant life, invertebrates, rocks, reefs or corals. The next step is exploring structures and wrecks. Wreck diving occurs when anyone sees or bumps into man made objects underwater which are fragmented, dismantled, damaged, dilapidated, ruined or otherwise wrecked. My first formal “check out” dives, as they were called in back in the early 60’s, were in a more Dive Computers 101 http:node32">Computer

Think back to your last dive, what could have gone wrong? If something did go wrong would you have known exactly what to do? When was the last time you practiced diving emergency drills - has it been since your open water class ten years ago? The point of the exercise is to get you to think about the unexpected, a diving emergency. Sooner or later with enough dives something will happen, it probably will be something minor but are you prepared?

This incident occurred nearly 13 years ago. I had just returned from the NSS-CDS Workshop and was helping a fellow cave instructor teach. The Memorial Day weekend and the Workshop meant that there were plenty of divers at the springs and sinks of North-Central Florida. We decided that Sunday night we would get away from the group for a fun dive and determine the degree of difficulty in diving Cow Spring on the upstream side with back-mounted doubles, rather than a sidemount more Challenges Face Handicapped Students and Their Instructors http:node24">HSA
