Interesting video

[wtdrm]

This is a great video. I am fortunate enough to have learned from the best. Ron Benson, for all of his personality faults is one of, if not the best, most accomplished divers/instructors we have in this market. In fact I think he was John J's 1st tech instructor. I have dove the CCR, albeit in a pool environment. I do own and regularly dive a Dolphin SCR and I think John also started on a Dolphin SCR. John as you know is a very accomplished diver and an instructor on the Inspiration as well. I received my training from CN111, who was trained by Ron B. The #1 thing beaten into my head was, 'if something feels wrong it is, switch to OC and abort the dive. Ron and Chuck believe in carrying a separate bailout. So do I.
I had 1 dive that was similar to this persons experience.
I had left the cover off of my scrubber cannister fro a couple of weeks. ( I didnt know any better?), I know I was told to not do that, however I just didn't realize the ramifications.
During the dive I started to feel just like this guy did, Rule # 1 (switch to OC and abort the dive. I did just that. I always carry a 30CF pony plus I have an air 2 on my Drager bottle. I switched, told my buddy what I was doing and we surfaced. I am still alive today. Thanks to Ron and Chuck.
I have roughly 120 dives on the Dolphin. For me it is a great fun tool. However it is still a machine and I don't trust  machines.
Anyway, CN111 is  not instructing anymore, however don't be afraid of the re breather world. They are a great tool in their place.
The fact that people were reusing the scrubber is just plain frugality. Scrubber is about 10-15 dollars per fill. What is their life worth.
John may do a re breather intro at sometime in the future. If he does, attend. even though you may not ever want to dive one, remember "a good diver is always learning". i take that 1 more step. " a good diver is always learning"
