It always pays to be prepared when scuba diving. We could get into sticky situations underwater and survival is largely determined by reinforcements made in terms of scuba equipment. Scuba divers are advised to conduct an ascent with at least 500 psi of pressure remaining in the cylinder tank. But then again, it is possible to lose track of elapsed time and gas consumption in the exploration of amazing flora and fauna.
In that case, imagine what it would be like to run out of air a few hundred feet underwater. That might just be a reason for extreme panic to the unprepared diver; but not for the diver who is all set up for a worst case scenario and geared with the right scuba equipment to resolve pertinent underwater mishaps. Cautious divers always carry with them an extra air source or pony bottle during the dive. One of the best EAS in the market today endorsed by Scuba Diving Magazine is the 6 cubic feet Extra Air Source (EAS) that is outfitted with an on and off valve. Find below a rundown of recommendable features that should entice you not to dive without this lightweight and dependable piece of scuba equipment.
Small and Lightweight. You would be amazed at how small and lightweight this air source is. In fact, you would barely notice its weight along with other scuba equipment strapped to your buoyancy compensator device; unless of course you run out of air in the course of the dive. Even more surprising is how something so small could hold such a large volume of compressed air to solely sustain an ascend that commences from the recreational limits up to the surface.
Compact and Functional. While outlined with features similar to regular diving cylinders and scuba regulator sets, this EAS is by far more compact than any other piece of scuba equipment. The air source's mechanism comprise of pressure ports and valves that operate with first and second stages to convey breathable air to the scuba diver. Two low pressure (LP) and 2 high pressure (HP) ports connect to its standard piston first stage. The second stage mechanism connects to an LP port and the optional pressure gauge while connecting to the HP ports is a quick disconnect fill valve. The second stage also features a silicone exhaust valve and mouthpiece.
Reliable and High Performance. Scuba Diving Magazine sampled this air supply and the verdict: It is the only bailout bottle or EAS that could ferry you to the surface safely and comfortably from a depth of 132 feet. Now that speaks a lot about the performance and reliability of this EAS.
