That no one has mentioned the "mamalian immersion response" or whatever name you learned it as. It's the technique where you breath without a mask at the surface (snorkel) and then at 15' or so (about 10 mins each) And then go do your dive.....the heartrates drop dramatically (in some cases...

Now I look at "twinssetup" on the website and see all the pics of how you set them up on regular bc's or BP's. For what you want to do, looks like a no brainer..... Darlene

But I understand the "gotta make what you got to work with work" predicament. Will the same bands setup work with a BP/wing, or is it contoured to fit the plastic backpiece of the Knighthawk specifically? If you can use it with a bp, then that makes it all much more cost effective. Good luck...

certainly not the conditions I'd wish to dive in either. But reading your post, finally crystalized in my mind, what I think is one of the things that foment resentment towards DIR. While I've not seen anyone credible ever say that GUE doesn't produce excellently trained divers/teams...Thosed...

So what was your point, ... Let's wait and see if they pass the test of time before arbitrarily deciding seperate bladders are the equivalent of quality.

phree, most tech courses expect you to have completed Rescue Diver (or it's equivalent)...Rescue requires AOW....Rescue is probably considered the most important class you'll ever take.... Do AOW and Rescue, then ponder the future..... The money will have been well spent. Darlene

"Nearest I can guess is they figure if you can handle a controlled ascent and a couple deco gasses after having the snot narced out of you, you can handle about anything. " That about sums up task loading though, ...and as you say, the normoxic part of Advanced was a baby step from there...

On this course. It really seems like an excellent course, GUE produces some excellent divers, but it's NOT what would be thought of as recreational in the usual use of the term. If you look at the 5thD site: http://www.fifthd.com/itindex.htm you can find info about it. It's a very...

Follow a pretty logical break point between the two. Entry is strictly a normoxic mix course.... You can breath backgas at the surface, and descend on it..(worst case scneario, you could deco on it too)......depth is limited by PO2. (Although 200' seems to be pushing it for 21%, which is TDI's...

Most of us that spend much time in the water have pretty thin blood, so to speak. Must be an acclamation thing. It's common to see instructors and DMs layering in the cooler months. Most seem to favor the sleeveless vest (without hood) under the wetsuit. When it gets colder they add the shorty...

are you using...... I see this often in the tourist divers using a rental shorty. (They may have been fine in a full suit) Try moving some of the weight from the belt to the tank's cam band (they have small pouches specifically for this) or trim pockets on your BC if you have them. Moving weight...

and as such, seldom are accorded the maintainance they deserve. To compound the problem, they are routinely dragged thru the sand, muck amd bounced off rocks and coral heads. If you maintain your inflator as well as your regulator, you can expect an equally long and trouble free life. You...

Does that make ya happy now..... I'd still like to see what would happen at hydro.. Darlene

on that one. If they say it's up to the hydro test, as to whether to use it or not, I'd have to go with the experts for sure. Now what would would really be helpfull, would be for COVCI to chime in here, since that's his business, and he could give us the results of years of experience about...

I had the phrase already copied, but forgot to paste, lol Glad you got it up there. Darlene

That is because we have all been trained the same way, our gear is identical, and we provide predictable responses to issues that might arise. In this way, (blank) divers make a cohesive team. In any (blank) class, you learn that situational awareness and teamwork is paramount. Now who gets...

thrown in for good measure, Everyone basically concured that the concept of "self perpetuating negative bouyancy" is a total crock. The "weak inflator" thing holds no logic, Any inflator fills the bc as fast at any depth as fast as it does at the surface. If it doesn't seem fast enough, you...

for doubles....We've had threads on that before, That setup would probably be the best choice, the only choice if you're renting tanks like when travelling. Remenber that the K'hawk has the 5/16" holes only about 8" apart, so normally configured banded doubles won't fit. You also have to use...

is indeed possible, and would be faster ...by what, 3 or 4 seconds to max inflation!.. A whopping 10 feet max at a 120' /min plus descent rate. .. And at a risk of damaging the bc and failure..only room for 1 fully inflated bladdder in there, how do you know when both are half inflated and it's...

and also with a 7 mil (occasionally). What I found to work here with Al80's (doubles) and salt water is about 22# to 24# total. Dive Rite's 7# trim weight is a handy option. The other tech diver here has it on the tank..it fits the band's spacing, .... that configuration tips me head down...
