What's in the box: 1st Stage, 2nd Stage, LP Hose, Owners Manual

Aeris' 400 Pro regulator's pneumatically-balanced second stage will be the work horse of your dive gear; it will keep you breathing easily dive after dive The diver-adjustable breathing valve allows you to control the airflow to match your breathing rate and body's air needs High performance over-balanced diaphragm first stage with environmental seal The first stage has two HP and 4 LP ports, weighs 29 oz (822 g) The all chrome plated marine brass first stage regulator is an over balanced diaphragm design which is environmentally sealed 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

Taking another stride beyond common second stage engineering, the AT400 Pro features a pneumatically balanced valve that maintains a preferred breathing resistance throughout the dive Set it once and the AT400 Pro automatically adjusts to make breathing as easy at 100' (30 meters) as it is at 30' (9 meters) - with no additional manual adjustment A simple twist of the AT400 Pro's adjustment knob enables complete control set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change

The 400 Pro's lightweight design and patented orthodontic mouthpiece mean you'll be comfortable and breathing easily throughout your dive and won't face post-dive jaw discomfort once you've returned to the surface Regulator comes with a 30" (76 2 cm) Hose The 400 Pro second stage with an outer ring diameter of only 2 67" (6 8 cm) and 5 4 oz (153 g) weight The Pro's second stage is made from an ABS/Polycarbonate composite blend of materials making it both extremely rugged and lightweight, reducing jaw fatigue on extended dives The 400 Pro 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 Second stage comes with a venturi control switch and diver adjustable inhalation The venturi assist deflector vane directs airflow from the valve directly to the mouthpiece producing a smooth "venturi assisted" inhalation Turning the venturi assist down, to a pre-dive position, prevents regulator free-flow while on the surface All Aeris regulators come with a owner's manual and a 24 month limited warranty
