The video editing was all Rick. He's The Man. If co-pilot is the dude in the middle, thanks :) Actually I think Rick (in the white tanks towards the end) has one of the cleanest frogs I've seen. I never feel like I am getting my feet bent in enough.

I refuse, on general principal, to get on the happy-birthday bandwagon. Sorry, Willy. :D

That's true.. if everyone followed the same rules then there would be no confusion and if my aunt had balls, she'd be my uncle (can you say balls on scubaboard?). Different cave instructors are obviously teaching different methods and arguing those methods isn't going to solve the problem...

Btw, I know of another cave instructor that is teaching the following: If an arrow ever contradicts your exit, lay your own personal arrow down right past it pointing to your own exit. I'm not saying I like that guys method but if you ever find yourself lost in a cave that one of his students...

That's what I was taught. One reason I posted this is to gain an understanding of what others are doing. I may change my methods someday but considering the methods I stated are obviously being taught by some popular cave instructors (H2Andy seems to have been taught the same methods), people...

Yes, if its crowded (e.g. a line already between the arrows), I'll place my own arrow. Sliding isn't a terrible big issue but I just want to make sure my line stays put and I want my directional marker to be right at the end of it (doing a lights out drill crossing jumps sure is a lot more fun...

I have no idea what 2) and 3) are but your point is well taken and very expertly made by whomever wrote that.

I was referring to the unmarked jump where there are no double arrows. When I am in agreement with the double arrows provided its not crowded, I'll just tie in between them.

No concern with the jump line sliding around on the main line? That is the reason I was taught to use an arrow in this case.

I had different instructors for cavern/intro and apprentice/full. With finding the line, I perfer my intro instructors method of using the clip to indicate direction as if I later realize I went the wrong way, it takes 2 seconds to switch the clip but quite a while to switch the arrow (unclip...

With an AL tank, yes I would imagine a standard weight integrated backinflate would tend to push you face down as the weights are in the front and all the lift is in the back (an empty tank and the air cell). I agree with MSilva but I too am a minimalist. Furthermore, when you see BC's with...

I was curious what different methods are out there for arrow/cookie placement in the following scenarios: Change of direction of the permanent arrows: Mark the planned exit side with a cookie, make mental note that the arrows are now pointing away from my exit Passing a T or Y: Place a...

As far as I know, the only gases that are usually placed into cylinders with CGA-580 valves are nitrogen, helium, argon and CO2. I'd have to do the math but I'm guessing that if they emptied the cylinder before filling (e.g. drained it down to 14.7 psi) the only gas in that list that could...

Yep, talk to the supplier. For our gas, he confirmed it all came out of the same storage tank. The difference between the grades is the paper work they fill out and vacuuming the tanks. Just for a bit of a warm fuzzy, we are getting high purity for less than $70.

A rec wing? I'm sure you've heard the expression "Jack of all trades, master of none." That's the rec wing. Dive Rite is trying to make a wing that can handle singles and doubles and does neither very well (at least that's the conventional wisdom, never dove one myself but it does seem quite...

Here in the DFW area, the cheapest classes are to be had for around $250 but that's usually with the caveat that you purchase your mask/fins and snorkel with them. If you want her to experience diving cheaply, you simply can't beat the discover scuba class. If she decides she likes it and when...

If you can find a private class for $200, go for it. Good luck though.

I hate LDS's as much as the next guy but they do not make a profit on training. They make a profit off of selling the new diver gear. While it may have come naturally to you, there are many people for whom it doesn't. In case your girlfriend is one of them, you might want to consider a bit...

Can't imagine that wouldn't work in 72 deg water. Doesn't hurt to try.

The standard rushed certification is 10 hours in the pool, say 2 hours with of open water diving and some amount of classroom training (say 10 hours). At $50/hr, that's going to cost quite a bit more than the LDS bargin classes. You won't find an instructor that will give you two hours in a...
