why did GUE , DIR take so long to adopt sidemount.

[Rich Keller]

Just as the title says. I have heard that for years the GUE, DIR associations adamantly opposed the idea of having two separate cylinders without a manifold for cave diving (side mount). I have also heard that the dive community -Way Back- (don't know if it was GUE) opposed the doubles set up with manifold. Any long time divers remember the controversy and watch things come back full circle in regards to sidemount?

If we are talking about "way back" my guess on the doubles would be that they were against using a suicide bar, not the type of manifolds being used today.

Sidemount is a disaster waiting to happen. My AI transmitter is safely nestled in the nook of the reg, manifold and tank neck. In sidemount the transmitters are much more exposed. Not to mention that few dive computers display two tank pressures simultaneously. To each their own, but sidemount is scarry stuff to the novice sidemounter.

You're joking, right?
For those who may be unfamiliar with Sidemount, each tank has its own SPG which is on a 6" high pressure hose. Whether the hoses point up away from the tank or are aligned downward, the SPGs are easily checked without use of AI transmitters. Adding transmitters would potentially interfere with the bungee system that supports the the valve end of the tank, and is not recommended.

For those unfamiliar with sidemount the SPG is mounted on whatever length hose is suitable for the dive. For example, in ****ty vis on a 24" hose to enable gas pressures to be monitored

I'm not too familiar with sidemount, so it seems, would you care to explain the concept of a 24" SPG hose?

 

[SillyQuestions]

In zero vis dives, from start to finish, you still need to check gas contents.

You place a 24" hose on the SPG and route it down and back up bands on the cylinder like a stage cylinder reg.

When you want to read the gauge, you pull it out, place it against your light so it glows, place it directly against your mask to read it. Then restow.

I have tried that and found I could only focus enough to tell the needle wasnt down in the low end. However with sidemount most rigs I have seen use a 6-9" hose.

Most people just "dive sidemount" rather than using sidemount to its full capabilities

If you're using sidemount to its "full capabilities", then you're going to want everything as streamlined as possible. Any extra loops act like Velcro in the cave. So short spg hoses...and some of us don't even use a long hose. There's no backmount divers to donate to

But, as others have said, to each their own.
