Product Information


Mares designed this XR set to satisfy divers looking for high-quality equipment to reach new goals. The 25XR - DR Full Tek Set encapsulates top-of-the-range Mares regulator technology.

The 25XR first stage is designed primarily to meet the needs of divers who use twin tanks or to be mounted on stages. The LP and HP ports are positioned on one side only and pre-oriented. The kit contains two 25XR first stages, one for the right side and one for the left. The hose ports are positioned so that they face downwards during assembly. This feature makes it ideal for cave diving, or in environments with limited passageways.

Thanks to the T.B.P antifreeze kit, the first stage is perfectly watertight, for better performance even when diving in cold water. It also prevents the entry of sand or particles, especially when diving in caves or polluted waters.

The reliability of this first stage is complemented by the A.S.T. (Auto Sealing Technology) system, which keeps the first stage clean and dry at all times and is oxygen, low temperature and high airflow tested.

The DR second stage has a full metal body. It is compact and robust, in high-strength nickel and chrome-plated brass. The high-performance second stage uses the V.A.D. system that offers a constant airflow at any depth. The special 'Mesh Grid' design of the cover prevents free-flow in the presence of strong currents.

This set includes:
• Two DR second stages
• Two 25XR first stages
• Two hoses (60 cm - 210 cm)
• One elastic neck regulator bungee
• One carabiner
