The Mares XR CR 25X Regulator is a paired twin set reg set for cave divers with a simple lightweight polymer 2nd stage and a reliable 1st stage. The CR 2nd stage has been designed for cave divers with a large soft purge button and a removable front cover.


CR 2nd Stage

The CR was made with cave divers in mind with an easily removed front cover to clean them out underwater without tools. A stable flow of air throughout each part of the inhalation thanks to the bypass tube and Vortex Assisted Design that creates a low pressure area inside the 2nd stage.

The design of the cover disperses water flow around the 2nd stage diaphragm to reduce chances of freeflows.


25X 1st Stage
Each 1st stage only has ports on one side and they are virtually mirror images of one-another so all of your hoses route down wards to prevent hose damage or snagging while leaving your valves free for access.

Each HP port is angled so your hose routes more naturally down around the shoulders of your cylinder.

Mares XR CR 25X 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.
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.
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
?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.
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.
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
Weight in Grams (approx)
?The weight includes the first stage (DIN fitting), hose and second stage.
