Mares designed this XR set to meet the needs of divers seeking high-quality equipment to achieve new goals. The 25XR-DR Full Tek Set encapsulates Mares’ top-of-the-range regulator technology, engineered for demanding technical diving.
The 25XR first stage is primarily designed for divers using twin tanks or stage configurations. Both LP and HP ports are positioned on one side only and pre-oriented, allowing for clean and efficient hose routing.
The kit includes two 25XR first stages, one for the right side and one for the left. Hose ports are positioned to face downwards during assembly, making this configuration ideal for cave diving or environments with restricted passageways, where streamlined setup and hose protection are critical.
Thanks to the T.B.P. antifreeze kit, the first stage is completely watertight, ensuring excellent performance even during cold-water dives. It also prevents the entry of sand or particles, making it ideal for cave diving or polluted water environments.
The reliability of the first stage is further enhanced by A.S.T. (Auto Sealing Technology), which keeps the stage clean and dry at all times. This system is oxygen-compatible, low-temperature tested, and designed for high airflow performance.
The DR second stage features a full metal body, compact and extremely robust, made from high-strength nickel-plated and chrome-plated brass. This high-performance stage uses the V.A.D. system, delivering constant airflow at any depth. The unique Mesh Grid cover design prevents free-flow even in strong currents.
This set includes
• 2 × DR second stages
• 2 × 25XR first stages
• 2 × hoses (60 cm and 210 cm)
• 1 × elastic neck regulator bungee
• 1 × carabiner
