Seac DX200 Regulator and Octo Package with SPG


The Seac DX 200 is your best bet if you want a versatile, lightweight regulator that delivers maximum performance. The Seac DX 200 Regulator has a first stage made from forged brass with sanded chrome finish material. The first stage design allows for minimum weight and size while ensuring consistent performance in demanding conditions, throughout the dive. The first stage features a high-performance balanced diaphragm design with total insulation from outside environment for maximum safety and ease of maintenance.

The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The standard diaphragm regulator does allow water into the mainspring chamber so that the diaphragm can perform this transmission of pressure changes. The first stage has 2 high pressure (HP) 7/16″” threaded ports and 4 low pressure (LP) 3/8″” threaded ports with 2 inclined at 20° and 2 inclined at 30° for proper hose routing.

The X200 second stage is a pneumatically balanced downstream design made from techno polymers, elastomers, with components in metal and cover with luxury technology treatment for abrasion and scratch resistance. Second stage features an inhalation adjustment knob to increase or decrease inhalation effort. The second stage is also equipped with a pre-dive/dive venturi switch to prevent second stage free flow on the surface or when swimming into a current. The X200 also incorporates low-friction metal components in an innovative, avant-garde design. Regulator come with a 30″” (76.2 cm) 3/8″” threaded low pressure hose, owner’s manual and weighs 40.2 oz. (1140 g).
