AMF MR-12II Vintage Swimaster Scuba Dive Regulator 2nd Stage

The AMF MR-12II Vintage Swimaster 2nd stage scuba dive regulator is a classic piece of diving equipment, hailing from the golden era of scuba diving. This regulator, produced by American Marine Fittings, is a reissue of the original Swimaster design, known for its reliability, simplicity, and ease of use.

The MR-12II regulator features a chrome-plated brass body, which not only adds to its vintage appeal but also offers durability and resistance to corrosion. The second stage housing is compact and ergonomically designed, allowing for comfortable mouthpiece positioning and effortless breathing.

This regulator employs a simple mechanism, with a diaphragm operating first stage and a piston-style second stage. The balanced diaphragm design ensures consistent air delivery, even in changing depths and temperatures. The second stage also incorporates an adjustable inhalation effort knob, enabling divers to customize their breathing resistance.

The MR-12II Swimaster regulator comes with a high-pressure hose, a 1/4" threaded low-pressure hose, and a 72-inch long, 3/8" threaded whip hose with a standard SCUBAPRO yoke. Additionally, it includes a 1/4" threaded adaptor for those who prefer a screw-in first stage.

The vintage Swimaster regulator is a perfect choice for traditional divers, technical divers, and collectors alike. Its nostalgic design and proven functionality make it a valuable addition to any scuba diving setup. By purchasing this regulator, you not only acquire a reliable and functional piece of equipment, but you also add a touch of history to your diving experience.

The AMF MR-12II Vintage Swimaster Swim Master Dive Regulator is a vintage scuba diving regulator that has gained popularity among collectors and some divers due to its unique design and historical significance. Here are some pros and cons to help you decide if this regulator is a good buy for you.

1. Unique Design: The AMF Swimaster is a classic piece of scuba diving equipment with a distinctive design that sets it apart from modern regulators.

2. Historical Significance: This regulator was first introduced in the 1960s and was widely used during the early days of scuba diving. Owning a vintage Swimaster is a way to connect with the history of the sport.

3. Reliability: Vintage regulators like the AMF Swimaster were built to last, and many still function well after decades of use.

4. Collector's Item: The AMF Swimaster is a highly sought-after collector's item, and its value is likely to appreciate over time.

1. Limited Functionality: Modern regulators offer features like adjustable breathing resistance, variable inflator hose, and integrated gauges that the AMF Swimaster does not have.

2. Safety Concerns: Vintage regulators may not meet the latest safety standards, and their performance may vary significantly from regulator to regulator.

3. Maintenance: Vintage regulators require more frequent maintenance than modern regulators, and it may be challenging to find replacement parts.

4. Cost: Vintage regulators like the AMF Swimaster can be expensive, especially if they are in good condition and fully functional.

In conclusion, the AMF MR-12II Vintage Swimaster Swim Master Dive Regulator is a unique and historically significant piece of scuba diving equipment. However, its limited functionality, safety concerns, and maintenance requirements make it more suitable for collectors than for regular use.

If you are a collector looking to add a classic regulator to your collection, the AMF Swimaster is an excellent choice. However, if you are a diver looking for a reliable and functional regulator for regular use, it is recommended that you consider a modern regulator instead.
