Switching to CCR?
Here’s my advice, from someone who’s living it right now.
1-Take your time finding the right instructor. This choice shapes everything that comes after — don’t rush it.
2-Do your homework on the unit itself. Every rebreather has its own mechanism, its own logic. What works for your buddy might not work for you, so find the one that actually fits.
3- Don’t expect the course to hand you comfort. It hands you the foundation
the ease comes after, through the hours you put in once the certification card is already in your hand.
4- And give yourself grace at the start. After years on open circuit, CCR will feel foreign for a while.
That’s not a sign you made the wrong call , it’s just where you are.
Stay patient, and it’ll become second nature, just like OC once did.
