Core Supreme Stage 3 Set

The AquaLung Core Supreme Stage 3 Set is a light weight cold water regulator that you can use at home in cold waters and abroad on holiday. The stage 3 adds an octo to your primary and 1st stage so all you need is a pressure gauge and a BCD hose.
The Aqua Lung Core Regulator is a cold water, environmentally sealed regulator with a range of features but without the expensive price tag. Lightweight but cold water rated; these regulators are perfect for the diver that likes to travel but also enjoys British diving.
Balanced 1st and 2nd Stages will deliver a consistent amount of air no matter the depth.
Auto Closure Device seals the internal mechanism of your first stage as soon as the pressure is released to help prevent moisture and contaminants from entering the first stage.
Heat Exchanger at the second stage end of the hose uses water temperature to warm air as it rushes through the valve; preventing exponential freeflows and freezing valves.
Venturi Adjustment can be adjusted during the dive and interrupts a free flowing second stage by redirecting the airflow toward the diaphragm.

Aqua Lung Core Supreme Stage 3 Set - Features
?This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air.
?The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing.
|Cold Water Rated|
?Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.
Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.
EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C.
|Cold & Warm Water|
?Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)
Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming.
?Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.
Balanced regulators are not affected by the cylinder pressure or depth.
Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers.
|High Pressure Ports|
?High pressure ports supply the pressure gauge and wireless transmitters for dive computers
|Low Pressure Ports|
?Low pressure ports supply the 2nd stages and inflator hoses
?An Unbalanced second stage is simply a lever operated valve that is opened and closed as the diaphragm is pulled inwards by the vacuum that is created when the diver inhales. An unbalanced second stage is affected by increased pressure at depth, slightly increasing the effort required to open the valve.
A Balanced second stage overcomes the effects of increased pressure by utilising a balancing chamber. This chamber takes some of the work away from the spring mechanism, allowing a smaller spring to be used which results in an easier breathe. As the chamber uses air to balance the valve it maintains the same resistance as the diver descends and ascends, keeping the inhalation effort the same.
|Weight in Grams (approx)|
?The weight includes the first stage (DIN fitting), hose and second stage.
