Full cave, trimix and technical wreck...
All my instructors have emphasized that you need to dive to your quals regularly to be able to do the dives safely...at least 5 dives to each "level" per year has been mentioned as an absolute minimum...The only issue is my cave-certification because I have to travel to dive (unless you count mines)...
I got certified because those kinds of dives are what I enjoy the most, every dive (almost), is an absolute pleaure the only downside is cost...Me and my buddy are starting to work our way up to 2hr RTs, doing it slowly means that we have time to enjoy every step of the way...the only issue is p-valves...I will propably have to give up and get one :11: ...
