Gas planning question

[flots am]

Sadly nothing to do with why sm is good for a reef dive. Thanks for replying.

What part of "100% redundant, almost impossible to run out of gas and easy to get back on the boat" makes it not good for a reef dive?

Why are you bothering with this discussion? He is spending his time on transmit, not receive.

Unfortunately, not all back mount divers are able to operate the valves, or at least they are not able to operate them fast enough. Two minutes to close the valve -> not cool.

Shutting a post and the iso at the same time should be a 2-3 second task, and you can get the iso and try both posts to confirm the problem in less than 5 seconds if you're diving the iso open only enough to balance the tanks. The concept of minute doesn't even factor into it.

Are there divers whose mobility issues preclude that kind of speed no matter how correctly they set up their doubles/harnesses and no matter how much they practice the skill? Sure -- and they have no business diving BM.

2-3 seconds? 5 seconds? I've never seen anyone that fast.

You will need to post a video of the incredible speed...

You guys crack me up.

Valve hitting you in the head? I know I know! The worlds most complicated side mount system is the solution!!

or just move the tank lower.

Hilarious.

Then move your tank lower AJ, dive it low-rider style with a poodle-jacket. . . I choose to dispense with backmount single tank in this instance all together --period.

I'd be impressed. It takes me more than three seconds to seconds to turn off a tank that's sitting in front of me.

It's just so bizarre that I can't look away.

Always one for extremes...

Sidemount in open water reef diving allows me to tilt my head back comfortably to look up --at that huge Manta Ray passing inches over my forehead (unlike with. BP/W & fixed too high single tank adapter, head banging the back of my skull on the 1st stage/tank cylinder valve). . .

That's more like it.

Nice answer Kev. I prefer it when people think about the why

I fail to see how the standard buddy system isn't an easier alternative to carrying an independent system in a standard OW dive.

Think of this why. I like lots of cheeses. They all have their merits. But for me Mozarella is the best for a pizza. Now you can argue that Stilton is a better cheese and I'd I agree with you to a point, but I'm not going to spread it thickly on my deep pan.

That's all I'm trying to say.

Because I like to know that my emergency gas actually exists and not have a little thought in the back of my head that says "Does my buddy really have enough spare gas to save us both at any time?"

I'll dive with pretty much anybody who isn't actively dangerous, but the list of people I'll rely on to save my life in an emergency is pretty short.

Buddies are nice for when you want to go out drinking, or when you can't quite get the last few inches of the drysuit zipper because you're too cold and stiff and can't feel your fingers. For "not running out of gas" I prefer a second tank and reg.

Since I'm one of a select few of my friends that has not yet collapsed a disk or two in their spine and hasn't completely blown out any important joints, I really like having the ability to reboard a boat without carrying 130 pounds of steel and lead.
