Mares Cold-Water Regulator – All-Metal Performance for Southern California Diving
Designed for extreme cold-water reliability, this Mares all-metal regulator system delivers exceptional breathing performance in demanding environments. Built for Southern California diving, where colder Pacific temperatures, kelp forests, and deeper profiles are common, this regulator provides smooth airflow, durability, and confidence at any depth.
Combining an all-metal second stage with a balanced diaphragm first stage, this system is ideal for divers who want dependable performance in cold water, long bottom times, and variable conditions.
Second Stage – Smooth, Natural Breathing in Cold Water
The all-metal second stage is engineered to perform flawlessly even in extreme cold-water conditions, reducing the risk of freeflows while delivering consistent airflow.
Key Second Stage Features:
-
All-Metal Technology – Improves thermal conductivity for reliable cold-water performance
-
Extreme Cold-Water Rated – Ideal for Pacific diving and thermoclines
-
VAD (Vortex Assisted Design) – Delivers natural, effortless breathing at any depth
-
High Air Flow Design – Supports demanding dive profiles
