Hi approaching my one hundreth dive which will be in cozumel next week. Planning on taking gue fundamentals and getting a dry suit. Want to really start to dial in buoyancy. and trim this year. I am a retired anesthesiologist who did a bunch of closed circuit cases early in my career and find ccr fascinating. Eventually hope to head down that route. Would love a book recommendation on the subject to review basic concepts as. my. previous. experience is. really in no way related to ccr diving and. the. complexities envolved
