CM Resources
User Manuals
At Choptima.com we strive to provide you all the resources you need for your Dive Rite O2ptima CM. From the newest rebreather diver to the seasoned instructor, we all need reference materials to review. Our goal with this page is to aggregate all the O2ptima CM forms, manuals, links, and helpful videos in one spot so you have a CM O2ptima reference library at your disposal. If there is something we are missing reach out to us and we will get it added. This is a community CM library.
