The Mares Abyss Octopus is designed to be paired with the matching Abyss regulator to provide a full high performance coldwater regulator set up. The Abyss uses a full metal housing to provide excellent thermal transfer properties that help to improve cold water reliability and performance.
A bypass tube delivers air directly to the mouthpiece for rapid response that also works to create a low pressure area behind the diaphragm, drawing it inwards to opening the valve faster and wider for increased flow. This prevents a fluttering breathe so you always get a smooth delivery of air.
The Abyss Octopus is fitted with a mesh grid design that helps to reduce the impact that strong currents has on the diaphragm which might otherwise cause the valve to flutter or cause freeflows. The octopus also has a lightweight and flexible braided hose for increased safety and strength. The braided hose is significantly more resistant to UV and contamination damage that would quickly reduce the integrity of a rubber hose.

Mares Abyss Octopus - 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.
?All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.
Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run.
