What is decompression all about?

Decompression is necessary whenever a diver wishes to dive in depths which go under 130 feet. If a diver tries to go deeper than 130 feet into water without following decompression procedures he would instantly notice that his air starts running low and would feel effects of pressure in his body.

Therefore, if you wish to practice deep diving you must learn how decompression works and how to follow indications necessary in order to succeed at practice of sport. First of all, you must be aware that you need to use specialized gears and plan your decompression in order to be ready when you need it.

Sometimes decompression diving is called ceiling diving. This is due to fact that this kind of diving involves passing a ceiling or barrier at right time and by following proper instructions. Divers should not practice this activity without right amount of experience and knowledge or it could become very dangerous and cause them problems such as decompression sickness or air embolism.

Paintball guns go high-tech

SITE Manufacturing (Redding, Calif.) has taken information attained during more than 23 years of fabricating hi-tech carbon composite components, such as telescope housings and applied it to sport of paintball. "One year around Christmas, we decided we wanted to do something else," said SITE plant manager Dave Weir. " We spent next three months scheming and developing an all-carbon-fiber composite paintball gun barrel." The product was ST!FFI, a tournament-quality barrel with a stepped bore (0.002 larger at 5 inches) available in one of a selection of bore sizes in 10-, 12-, 14- or 16-inch (254 mm, 305 mm, 356 mm or 406 mm) lengths or as part of a ST!FFI SW!TCH kit (with nylon carrying case) containing a 0.695-inch bore barrel with four exchangeable sizing breeches (0.685 to 0.691 inch, in 0.002-inch intervals) used to adjust barrel to minor variations in available paintball ammo.
