Cave Diving

3 points by martin-ro 10y ago

I saw (2) submits being up-voted or got plenty comments here on HN about caves and diving them. I do make a living as an "hacker" or "engineer" what ever you like to call it. But my passion is diving. Me and my business partner actually working on a start up focused on that sport. For myself the recreational sort of diving became less challenging for several reasons over time. Now I do caves and/or very deep dives mostly into caves or wrecks. I just uploaded some of my videos to YouTube (https://www.youtube.com/channel/UCB-fZxXha894oN8gPjS_VdA). I had them on my Vimeo (https://vimeo.com/user3271006/videos) channel only before. I found the comments about these stories (https://news.ycombinator.com/item?id=11658110) very interesting. I'm still transferring some of the videos from Vimeo to YouTube. AMA.

The danger! Do you ever get claustrophobic? The basic diving courses I've taken made me appreciate normal atmospheric pressure, lack of nitrogen build up and ability to breathe naturally much more than previously :) And that was in open water. I was a pretty fearless kid, but I guess if you get out of the adrenalin habit, or just get old, the fear creeps back in. What's your take?

  Yes, i do get claustrophobic (rarely, but yes). If the effort to go forward is hard, you need to take in account that there won't be space to turn around and swim it head first back. So you need to keep in mind that you might need to "finger walk" yourself back - backwards! That is sometimes an adrenaline accelerator and keeps you from doing stupid stuff. About nitrogen: probably one of the most impotent parts is gas planing: we transport and switch gases suitebale for the depth.. before every dive there is a lot of math.

    Thanks for getting back to me. I have vague memories of the logical, reasoned approach helping to squash the irrational fears, so can see a little into how you handle it. Will check out your vids later, excited to see them.

Hi, thanks for opening this discussion. I have the advanced open water certification and I would like to try cave diving. first question: with how many immersions is recommended to start in cave diving ? . 2: which places do you consider the best for practicing this ?
