I have only 3 solo dives but plan on adding many more (with my buddy 19cf pony). I was a bit concerned the first time but planning and love of diving got me back in. I was able to focus on my skills and look at what I wanted without a tank breathing buddy. PS I didn't tell my OW, AOW, or Rescue instructors when we talked about diving. I thought about it and then the words of my OW instructor floated through my head (never, never enter the water without your buddy.) I just share my solo dive experiences with my local tech. dive shop. There I gain so much more knowledge, with people who really do it.
