Yes but I notice you didn't define the line your self. The point people are trying to make is that the curve up to tech diving is a gradual slope for many and not a sharp delineation. So in that respect it is just it is just diving in that one has to answer the question, "Do I have the...

Interesting. I just looked at my cave 1 card and it says doubles in the comments field. would they then allow me to dive doubles at Ginnie? Kevin

four points of thoughts come to mind. 1) I think its indicative how different geographical areas of diving come up with different solutions. Case in point that in the NorthEast, a lot of people are familiar with the various protocols for setting and moving hooks on the wreck. In other areas...

I would rather see it a free for all and let anybody post with one exception. If a moderator feels a post has clearly stepped over line, they get banned for a week. Then just double it each time they misbehave.

Lynne, A couple of methods are possible. 1st - David's solution will work, but you may find it a bit more difficult if you have smaller hands then the meat hooks David calls fingers. Alternate method #1) Starting from the position of scootering with your middle finger on the trigger...

Apparently it doesn't allow solo diving either. Reading through the workbook they added a 6th rule to the accident analysis.... Solo diving.

Ah I see I was mistaken. I bow to your superior wisdom. NAUI Cave 2 = Best cave class EVER.

Daniel, Glad to know that you have dubbed NAUI's Cave 2 the best cave class ever. That really means a lot even if there hasn't been a NAUI Cave 2 class taught yet. GUE doesn't teach that stuff because their philosophy is against doing such dives. Why in the world should they teach...

It's an overhead because you can't ascend directly to the surface and Its a swimthrough because you can.... swim through it.

Sorry This one time, this guy wearing a FFM was rude to me. And another time, they were all arogant and excluded me from the club becuase I didnt have a FFM. Then they wouldnt let me dive with them because I didnt have a FFM with voice features. This was even though they were only diving...

Ok not that its no longer DIR related.... I like to bungie a slate accross my forehead. It super convienent as I always know where it is, if I need to write a note to my buddy its a snap for him to read it as he just has to shine his light on it. Seriously folks. Arguement is now...

And what does DIR say about subsituting equipment for skill? :D

Some of the ideas explained to me on why wetnotes are to be preferred. 1) Multiple items can be written down in them and yet still leave space for further notes. For example, I have navigation aids for dive sites, tank factor conversions, emergency contact & DAN information, equipment serial...

So is Heather (Chickdiver) no longer DIR then? Have you all thrown her off the reservation?

I think what he is saying is not clear. he said to subtract 100 psi from 1/3rds but didnt specify which 3rds. And besides if diver A had double 85's with 3600psi and diver B had double 95's with 2700psi Would you now ask diver B to penetrate to 1100psi? 900 psi? or 800psi? Where does...

Ok lets work this out: Diver A has double 85's with 2700psi. Diver B has double 95's with 3600psi. Diver A has 172 cuft of gas Diver B has 259 cuft of gas Diver A has the smaller amount of gas so penitration gas is set at 57cuft (172/3) Diver A's turn is 1800psi (2700 -...

Mike, My examples were worst case examples. So no matter what we choose, we will always hit our turn pressure at the same time. This is what validates the gas plan. One's sac rate is always subject to change during the dive. While one might start out and plan for the same sac rate it...

Ok so lets work this out: Diver A Turns at 1800 (2700- (2700/3)) Diver B turns at 2700 (3600- (2700/3)) Both divers have a nice cool dive and they hit their turn pressures at the same time. (diver B's sac rate is worse that diver A's Diver A has used 57cuft of gas and has 115 cuft...

So lets work this rule out: Diver A has double 85's with 2700psi. Diver B has double 95's with 3600psi. Diver A's turn is 1800psi (2700 - (2700/3)) Diver B's turn is 2500psi (3600 - (3600/3 - 100)) Both of them have a cool dive and reach their turn pressure at the same time. (diver...
