What's in the box: 1'st and 2'nd Stage Regulators with LP Hose and Owner's Manual
The AT 600 ION is the latest iteration of the flagship AERIS ION Regulator Line. The AT 600 ION has a swivel and by adding an ultra-flexible braided 30" (76.2 cm) MAXFLEX hose makes it one comfortable regulator Paired with the ultra-compact AT 600; a brand new over-balance diaphragm first stage weighing in at just 29 oz (822.14 g).
The AT 600 is a High Performance First Stage with Environmental Seal. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The standard Diaphragm Regulator does allow water into the mainspring chamber so that the diaphragm can perform this transmission of pressure changes. The first stage has 4 Low Pressure Ports (LP) and 1 High Pressure Port (HP) and is NITROX compatible to 40% out of the box.
The pneumatically balanced demand valve of the Ion Second Stage along with a highly responsive design allows this regulator to provide a high volume of airflow with even the slightest inhalation effort, making it seem nearly effortless to breathe at any depth. All in a second stage barely wider than the mouthpiece. The ION is AERIS' smallest and most streamlined second stage ever with an outer ring diameter of only 2.3" (5.8 cm) and 5.4 oz (153 g) weight. The ION's second stage is made from an ABS/Polycarbonate composite blend of materials making the ION both extremely rugged and lightweight, reducing jaw fatigue on extended dives. The extremely lightweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized to prevent corrosion.
A common objection to typical adjustable second stages is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. The ION features a pneumatically balanced valve that maintains a preferred breathing resistance throughout the dive. Set it once and the ION automatically adjusts to make breathing as easy at 100' (30 meters) as it is at 30' (10 meters). Ever notice that nearly every picture you see of a diver, their regulator looks like it's not the least bit comfortable? The ION features a swivel and by adding an ultra-flexible braided MAXFLEX hose.
The ION's high-tech accent rings are machined from a solid piece of aircraft Aluminum, then hard-anodized utilizing a unique process to prevent corrosion AERIS regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows AERIS the ability to model and test performance while still in the early stages of development. The ION's unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth VENTURI-Assisted inhalation. Adding to the ION's rugged durability, an oversized integrated purge button is utilized to eliminate the possibility of free-flow caused by trapped sand. To further reduce jaw fatigue, the ION features a new patented orthodontic mouthpiece with high density bite tabs designed to accommodate the natural overbite of the human jaw. The ION is classified as being suitable for use with NITROX breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. The regulator comes with a Comprehensive Owner's Manual and is covered by a 24 month limited warranty.
