Hey everyone! It is time for me to learn some new letters (CCR) to add to my SCUBA experience. I have been diving OC since 1977, am a techncial dive instructor and never thought that it would be worth the money to take the jump, thngs change. In the last couple years I have had the opportunity to dive with a couple of rebreather divers and was impressed with the ease in which they were able to get close to marine life to take pictures. After looking at different units for the last 2 years I finally settled this year on a Prism, and signed up to take a class with Ron. I am looking forward to 1000s of hours diving this unit. I will post again after my class in October. I look forward to lots of exciting posts with this group.
