I would like to take the time to say that I am sorry to the team of four doing their cavern and Intro class at Twin on the morning of 1/20 around 1030-1100. When I came out of the entrance into the open water area, I pulled my dump valve to release some air, and it stuck open. Being in 5ft of water, I hit the silty bottom in about 2 sec and made a mess.
I wanted to those to know why we they has to take 10 min floating till the area cleared out.
Did you by any chance swap the pull dump from low to high?
I think that I read somewhere that you have the SMS100 (or something similar) with mods (as per Edd). The reason I ask this is that I did the same swap and when I pulled open the dump at about 120' in Hudson Grotto it stuck open and I did a header into a couple of feet of silt. In deep open water I would have been in real deep (literally) doo-doo as I was in a wet suit. Needless to say, I put the dump/inflator back to stock and make sure I have redundant buoyancy (drysuit or lift bag when wet) . I also like to be able to vent from the bottom in case I need to (as when getting foot light in a dry suit).
I've also had problems with a leaking dump valve after moving it to the bottom. Did not care for that and moved it back again.
On the other hand, it does give a perfect excuse for trashing the viz! :-)
I have the both SMS and Nomad with Edds Mods and I was using the Nomad. I was diving wet also and back up inflation but it was so quick and shallow, it didnt matter. I have not changed them back as I know that sometimes it happens. After close inspection, it appeared that the spring was very weak and needs to be replaced after having alot of wear on it.
I have no issues dumping in any position. I changed the way I attached the Inflator hose, and it now allows me to use it in diff positions.
Yes, before I could blink, I stuck my arms out and went all the way up to my mask in the silt....Ill say there is some hard bottom about 3 ft under the silt there...LOL...
Wow, Way to man up!!! :clapper
There was an argument as to whether Twin looked like "chocolate milk" or a "caramel latte".
I feel for you, I did somewhat of the same in HITW . . . :(
I'm sure we silted it up a LOT more after you guys left... I've experienced some low vis situations fossil diving in the cooper river, but an air share drill while exiting the cavern resulted in a total blackout... all in all a great experience!
Can't wait to get back in cave country :)
It was not pretty, ill say that..
HansB, were you in the class???
Yep, Basic Cave Certified now!
I honestly have to say cavern and basic is the best SCUBA class I've taken to date, thanks to RN!
Lol! All I know is that the cavern was perfectly clear when I went to pick up my O2 bottle and when I looked up it was as though a silt bomb had gone off and all I could see was a faint glow from the entrance. :-)
Ah Ha! It was you :rollguyQuote:

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.
Welcome to cave diver forum where anything you post is subject to bashing in one form or another

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.
