TUSA RS-1001 Regulator

Yes, by isolating the internal components from contaminants like salt, sand, and chlorine, the sealed design significantly reduces the risk of corrosion and buildup. This generally leads to longer intervals between professional servicing compared to unsealed regulators.

Yes, the RS-1001 is cold water rated. The environmentally sealed first stage is specifically designed to prevent freezing and internal contamination, making it a reliable choice for diving in colder environments.

The surface/dive switch is a safety feature that helps prevent free-flow when you are at the surface. By switching it to 'surface' mode, you increase the breathing resistance slightly to stop the regulator from venting air unnecessarily until you are ready to submerge.

The diver-adjustable sensitivity control allows you to fine-tune the breathing resistance to your preference. You can tighten it to prevent free-flow or loosen it for easier inhalation, which is particularly helpful when you want to minimize effort at different depths.

The regulator comes with an orthodontic silicone mouthpiece designed to fit the natural shape of your jaw. This helps reduce jaw fatigue during extended underwater sessions, as you don't have to bite down as hard to keep the regulator in place.

The first stage is equipped with two high-pressure ports and four low-pressure ports. This provides plenty of flexibility to connect your primary second stage, an octopus, a pressure gauge, and a BCD inflator hose simultaneously.
