One must take advantage of the moment when you can give your dive buddy a hard time for something because soon you know you will do something and they will return the favor!

Very true!!

I just wanted to clarify what happened with this incident a little better. I have received some PM that were very helpful on things to check and do in the future but I also received some that were rude as hell and not appreciated. I understand the inportance of back up inflation, being safe, not silting things up and all. I am a very cautious diver and by no means meant for this to happen. I thought by being man enough to post on here and to let the class know that had to wait for it to clear was the right thing to do.

Upon exiting the hole from the cavern to OW, I had my pull dump stick and dump all of my air. When this occured, my feet were probally still at the edge of the rocks at the entrance hole. I was only about 3 ft above the bottom at the most. When I came out, I pulled to dump air for the ascent. The valve stuck, and before I could do ANYTHING, I hit the silt. I dive wet and do have a method for back up but BEING I WAS ON EXIT AND SO CLOSE TO THE BOTTOM, WHICH NO MATTER WHAT CANT BE CHANGED, THERE WAS NO TIME TO DO ANYTHING. No matter what you do, you have to exit the hole which requires you to be close to the bottom. I had no other issues on silting the hole until this happened.

I understand that if this happened back in the cave, things could have been bad. These are called accidents for a reason, I did not purposely silt the entrance. I had a malfunction in equip which ANYONE of you could of had at any moment. I have the back up measures for this in the event I would of HAD TIME to use it. While diving in the cave, I will do my best to stay at a height that allows for back up measures. Being that I had no control over it, its not like I had time to plan on it.

I hope this helps and makes some ppl understand what happened and that I didnt post to be bashed about it.

I really didn't mean to start an international incident when we cruised by and I said "hmmmm, that doesn't look good!". The cavern at Twin is notoriously easy to silt out, that's why the line was moved right to the entrance. I'm not sure it's a terrific place for training drills because it's so easy to trash it for everyone else.

Actually, the line was moved to the entrance just prior to the first NSS-CDS Annual Workshop. I extended it to the entrance in anticipation of several divers being in the area and diving it. I did the same thing at JB. I removed the gold line extension from JB but decided it would be best to leave it in place at Twin mainly because it's not accessible by land.

As for its ease in silting out, yes it does! It's great for that. I purposely take my students in there and have them run a line back to the stop sign hoping it tells on any poor technique. And if it doesn't I help it out a little so they can experience a true low visibility situation caused by silt under supervision.
