I made it a year of diving and have had a great time. Next year I want to focus on skills to be a better diver. I've heard of Advanced Wreck Penetration, which sounds interesting but I prefer to spend the next year diving and getting experience over certifications. I currently have Wreck and Deep certifications and next year I plan on doing a series of deep and wreck dives. Besides buoyancy, what are some skills or things I can practice to be a better wreck diver? Besides practicing CESA, what are some contingencies I can also practice at depth. Many thanks.
