What are the physical dimensions and weight of the Hollis 200LX Second Stage Regulator?

You should measure the available weight capacity on your buoyancy compensator before adding this to your gear. We selected this model for our comparison because it sits within the standard weight range for high-performance regulators.

Hollis 200LX dimensions and weight affect diver visibility and comfort

The Hollis 200LX is a second stage regulator, which is the part of the breathing system that allows a diver to inhale air from a tank. Because regulators must sit close to your face, these dimensions determine if the housing diameter clears the standard face mask or frame. A diver needs to ensure the body length does not interfere with their profile or snag on other gear during a descent. While the facts do not state if the weight changes when fully saturated, a metal and rubber construction typically maintains a consistent feel. This specific weight and size matter because a bulky second stage can obstruct peripheral vision or make the breathing setup feel unbalanced.

What to Check Before Buying the Hollis 200LX

Verify these physical constraints to ensure the regulator integrates with your existing scuba equipment:

• Check that the housing diameter clears your specific face mask frame to prevent pinched hoses.
• Ensure the mounting hardware and hose connections align with your preferred right or left-hand configuration.
• Verify that the 0.8-pound weight fits within your planned gear weight distribution.

Hollis 200LX Sizing and Weight Comparison

The Hollis 200LX serves a diver who prioritizes a compact, lightweight breathing interface. If you are a diver who requires a specialized sidemount configuration or a high-volume regulator for specific gas blends, you might look at alternatives that offer different internal flow characteristics. This model focuses on a standard profile that balances portability with the requirements of a primary breathing source.

You should choose the Hollis 200LX if you need a lightweight, 0.8-pound second stage that fits a standard profile and offers a reversible demand valve for various hose setups.
