The first Automag was invented in 1985, but was revised several times before its release in 1990. As one of the first generation of semi-automatic paintball markers, its blow forward design was unique. Made mostly from stainless steel, the valve system was the first to incorporate a pressure regulator directly into the marker.

The weapon was also known as the Windbüchse ("wind rifle" in German).One of the rifle's more famous associations is its use on the Lewis and Clark Expedition to explore and map the Louisiana Purchase of 1803.
A typical graph produced when testing the breathing performance of a diving regulator. The breathing performance of regulators is a measure of the ability of a breathing gas regulator to meet the demands placed on it at varying ambient pressures and temperatures, and under varying breathing loads, for the range of breathing gases it may be expected to deliver.
A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.
Regulator set Each primary sidemount cylinder requires a regulator 1st stage, a regulator second stage and a submersible pressure gauge (SPG). The left hand cylinder will also include a low-pressure inflator (LPI) for BCD inflation. If a drysuit is used, the drysuit inflator will be attached to the right hand cylinder.
A modified sidemount version of the RB80, called the RBK has been produced in three versions. It has a smaller scrubber capacity and is shorter, at 50cm, with the same diameter as the RB80. The RBK has been used as a sidemount, travel, and bailout rebreather and has advantages in long-range explorations through small passages. [1]
A Show of Affection. When it isn’t trying to mind-control you with its stare, your cat might just be showing you some affection. Looking at you intently with a long, unblinking stare is one of ...
A pony bottle or pony cylinder is a small diving cylinder which is fitted with an independent regulator, and is usually carried by a scuba diver as an auxiliary scuba set.In an emergency, such as depletion of the diver's main air supply, it can be used as an alternative air source or bailout bottle to allow a normal ascent in place of a controlled emergency swimming ascent.
