Zeagle"s regulators are US made, built under strict controls for quality in our own factory, using state of the art equipment and procedures. Your regulator is one of your most important pieces of gear. No matter what kind of diving you do, you can do it better with Zeagle. The Octo-Z Inflator replaces the conventional BC power inflator and second stage octopus by combining the functions of both into a single unit. When you"re taught how to dive you are given practice in buoyancy control more than any other skill. Once you start to dive every time you go underwater, fin the reef, or surface you use buoyancy control. All this time your octopus second stage regulator hangs un-used and out of mind. When a real life out-of-air situation occurs, the stress and anxiety mounts, and you find yourself fumbling for a piece of equipment you never use the Octopus! Combining your inflator devise (that you use on every dive) with your Octopus Regulator assures your ability to react properly when an out-of-air emergency occurs.
