Mares diaphragm first stages are ideal for cold water diving because the moving parts do not come into contact with the water. For diving in especially cold water, it is advisable to equip the Mares first stage with the CWD (Cold Water Diving) kit. The CWD kit is a device that completely insulates all parts of the first stage from direct contact with water.
The main spring cavity is completely isolated from the outside environment and protected against the formation of ice crystals. The CWD kit diaphragm, made of specially selected materials, encloses the main spring cavity and uses a mechanical piston to convey variations of ambient pressure due to changes in depth to the main diaphragm. The dry piston offers maximum sensitivity to changes in environmental pressure, ensuring faster and more precise regulation of intermediate pressure than other systems.
