Hi Walter (and everyone),
I truly respect and agree with your many many many postings on SB which lament the dumbing down of quickie scuba training. Obviously, to be under-trained (lack of knowledge, lack of skill-repetition) is all too often the first contributing factor in the cascade of events that culminate in a scuba tragedy.
Just as obvious: to block 75% of your normal field-of-view with a traditional flat mask can only harm, not help, safety. Anything that enhances
Situational
Awareness (SA) helps safety.
Laws prevent people with narrow vision from driving cars, or driving with sunglasses that have very wide temples which likewise block peripheral vision.
Here is a good Wikipedia article about SA.
Walter, you more than most people know of instances
when instructors lost sight of a student, who then got into trouble. In over 50% of scuba tragedies that start with an underwater "event," the surviving buddy had no idea that the victim was in distress. Only after the survivor surfaced, solo, did he / she begin to grasp what was unfolding. Do anything to improve your Situational Awareness, and you and your buddies will be safer.
Adoption of new technology always has a time-curve, but in recreational scuba in the USA, the time-delay is bizarre. Why did it take from 1956 to 1978 for the SPG to become "required" by the recreational scuba industry? Hmm... the SPG was called a "death-trap" by the insider
Skin Diver magazine, and many stores preached "the company line." Meanwhile, insider equipment companies manufactured and profited from J-valves, which were too-often responsible for dive fatalities. Their valve was patented, and they didn't want to share profits with companies that made gauges. After 22 years, countless deaths, and the threat of government intervention, the SPG was finally adopted.
I do not believe the products made by my company are perfect. And no, I never thought everyone would rush to wear contact lenses. But I get angry each time I read an accident report, knowing that poor SA was a contributing factor to the cascade of sad events. I'm the first to know that not everyone's going to wear contact lenses. I'm actually surprised that of the thousands of divers around the world using our mask, almost 900 have 20/20 vision. People trust their own eyes when they do a
proper A-to-B comparison.
The form-factor of our first mask, the 4.5DD, will remain optimal for acuity and field of vision, and future masks will be for 20/20 and other-vision divers who are unwilling to take that "leap of faith" to try contacts, or that <10% of the population who, for medical reasons, truly cannot wear contacts. We DO NOT recommend newbie 20/20 divers to use our Double-Dome mask -- learning to wear contacts + basic scuba skills is too much task loading.
