White Stag Sea 1000 Lung

The White Stag Sea 1000 Lung is a vintage single-hose scuba regulator produced by White Stag, a company active in the diving equipment market during the mid-20th century. These regulators were prominent in the 1960s and 1970s and are now considered collectible items among diving enthusiasts.

Design and Features:

• First Stage: The Sea Lung 1000 regulators typically feature a piston-type first stage, such as the “Deep 1,” designed for lower pressure tanks with a maximum service pressure of 2250 PSI. Notably, they have a small 3/8-inch diameter yoke screw, indicating their compatibility with lower pressure tanks.
• Second Stage: The second stage often utilizes a tilt valve mechanism, a design common in regulators of that era but different from the poppet-type valves used in modern equipment. Tilt valves require a first stage equipped with a safety relief valve to operate safely. However, the Deep 1 first stage associated with this regulator may lack such a relief valve, potentially posing safety concerns.

Collectibility and Usage:

Due to their age, White Stag Sea Lung 1000 regulators are primarily sought after by collectors and vintage diving equipment enthusiasts. Servicing these regulators can be challenging because parts are scarce, and the technology is outdated. Consequently, many choose to restore them for display purposes or limited, shallow-water use rather than for regular diving activities.

Availability:

Occasionally, these regulators appear on online marketplaces and vintage scuba equipment forums. For instance, a Vintage White Stag Sea Lung 1000 regulator was listed on WorthPoint, highlighting its appeal among collectors.

Safety Considerations:

If you’re considering using a White Stag Sea Lung 1000 regulator for diving, it’s crucial to have it thoroughly inspected and serviced by a professional familiar with vintage scuba equipment. Due to the potential difficulty in sourcing replacement parts and ensuring reliable performance, many divers opt to use such vintage regulators primarily for display or as part of a collection rather than for actual diving activities.

In summary, the White Stag Sea Lung 1000 regulator holds a notable place in the history of scuba diving equipment. While it may not be practical for modern diving without significant restoration efforts, it remains a valued piece for collectors and those interested in the evolution of diving technology.
