  1. A Different Method to Remove A Wetsuit If you haven't seen this video of a 7mm neoprene wetsuit being cut off an attractive young model in less than a minute with an EEZYCUT tool, it's worth a look. We especially like how she pirouettes and walks away from the camera at the end. Unfortunately, when divers with rescue training ...
  2. About the U.S. Diver Down Flag The red-and-white U.S. dive flag was invented in the early 1950's by Denzel James "Doc" Dockery. In 1953, he followed instructions published in Popular Science Magazine for building his own scuba device, and began experimenting with ways to make a living by working in the emerging sport. In ...
  3. Advice for Traveling with Rebreather Cylinders Regardless of the brand of rebreather it can be annoying to travel with cylinders because they are carefully examined by security personnel, and occasionally even confiscated. TSA says cylinders are allowed only if the cylinder has an open end. This means you must remove the valve and you must ...
  4. Learning From Analysis of Rebreather Deaths The June 2013 issue of Diving and Hyperbaric Medicine contains an excellent article that analyzes the causes of recreational closed-circuit rebreather fatalities. It concludes that while rebreathers have an intrinsically higher risk of mechanical failure as a result of their complexity, this can ...
  5. Are Rebreathers Safe? At Rebreather Forum 3 held in 2012, statistics were presented which suggest closed-circuit rebreather diving is five to ten times higher risk than open circuit scuba. Some of the statistical increase may be due to rebreathers enabling divers to attempt extreme dive profiles which are themselves ...
  6. Using the metal grommets...... Using the metal grommets, either the DR or the XS sleeve can easily be attached to the bottom or sides of any standard metal backplate using assembly screws or attached to the Transpac using medium quick links or the pear shaped quick links. We find that for this application, the plastic ...
  7. Backup Second Stages Traditionally, the backup second stage regulator has been a lower-performance lower-cost unbalanced design because it was thought to be less likely to free flow and less prone to problems. However, experience has demonstrated concerns with using a lower performance regulator under conditions ...
  8. Bailout/Deco Regulators Good work-of-breathing on bailout/deco regulators is very important to ensure proper gas exchange. A switch to a bailout bottle, especially if due to hypercapnia, is always a demanding situation. Low quality, improperly maintained or incorrectly tuned regulators can perform poorly regardless ...
  9. Basic Care and Maintenance for Your Guideline Reel Most overhead cavern and cave classes require three reels: one large "primary" reel with at least {400 ft | 120 m} of line, plus two smaller "safety" reels with about {140 ft | 45 m} of line. Many divers also carry one or more {50 ft | 15 m} or longer compact finger spools for gap jumps. ...
  10. A Battery Warning Means You Are Diving On Borrowed Time! The nature of the lithium chemistry batteries used to power virtually all dive computers and digital bottom timers on the market has important consequences to battery life and in particular to battery warnings. That is because while lithium chemistry batteries have a very long life, it ...
