The Mares Abyss 52x Regulator is a robust and smooth regulator packed full of features and perfect for both cold and warm waters.  The metal body of the Abyss makes it much stronger than traditional materials and also acts as a heat sync to improve cold water performance.



The Abyss 2nd stage is an all metal design which makes it strong and great for cold water diving.  As well as acting as a giant heat-sync to reduce the chances of free-flows it can also help to reduce the dryness of the air you're breathing by letting moisture from your breath condense inside the 2nd stage.  

The bypass tube uses Vortex Assisted Design to prevent fluttering so you get a smooth breath and reduces breathing resistance.



The 52x features Dynamic Flow Control which basically maximises airflow to you no matter the conditions.  Inside is an ACT Valve which increases durability by 600% compared to traditional valves so where some regulators will start to hiss over time because the valve ages the 52x will keep going for longer. Natural Convection Channel increases cold water performance by creating a flow of water over the 1st stage.

Mares Abyss 52x Regulator - Features

FeatureProduct Specification
Adjustable Inhalation
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. Close.
Adjustable Venturi
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. Close.
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. Close.
Cold & Warm Water
Environmentally sealed
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. Close.
First Stage
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. Close.
High Pressure Ports
High pressure ports supply the pressure gauge and wireless transmitters for dive computers Close.
Low Pressure Ports
Low pressure ports supply the 2nd stages and inflator hoses Close.
Service Information
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. Close.
1 Year - 100 Dives
Weight in Grams (approx)
The weight includes the first stage (DIN fitting), hose and second stage. Close.

Mares Abyss 52x Regulator

The regulator set, My needs reliability and the ability to use in cold water locations.

Also tested Sunday. Not able to test in what would be quite as cold as it can be in the UK for sure. However, the regulator set performed well
