Cataloged in 1963 the single stage Healthways SCUBA regulator was called the most dependable regulator in its class. This regulator breathes as good as any Mistral provided it is paired with a good soft diaphragm. The captured yoke nut is also somewhat unique. The major shortcoming of this regulator was the hose assembly and mouthpiece. Most were replaced with a US Divers hose assembly for easy breathing. The regulator sold for about $52.00 in 1963.
