I'm getting ready to set up my first sidemount regs. For my sidemount course, my instructor had me try SPGs in the various positions. Being a technophile, I'll be resolving SPG placement issues by using two transmitters for my Perdix AI instead of SPGs.

What I'm unsure of is whether the transmitters should go directly on the first stages pointing down or placed on 9" (23cm) hoses and tucked under the top band. For backmount, I recognize that putting the transmitter directly on a first stage increases the chances of it being broken off due to negligent handling. But in sidemount, it seems like it would be in a somewhat more protected position than backmount. A direct connection eliminates additional failure points. It also decreases the gap between the transmitter and the computer.

What's your thoughts/personal practice?
 
No hoses is fine, especially if the HP ports are directly vertical/at 90 degrees to the valve opening
 
What's your thoughts/personal practice?
My personal practice is to search SB for about a thousand threads on this subject before asking the question again. :)
 
I had the same question recently and it was answered in depth

Thank you. I'll go look for it in this forum. My initial search was bringing up tangential posts about transmitters vs. SPGs rather than direct mounting of the transmitter vs. use of a hose. I probably need to use different search terms.
 
I put mine directly on the 1st stage pointed 'down', this worked great for my steel tanks. On AL80's with the short neck though it caused the 1st stage to cant sideways so when I run rentals I'll put them on a short hose.
 
My 2c.
Directly attached and pointing down A-Ok
Attached on a short hose (any length) A-Ok
Directly attached and pointing up - NOT A-Ok. If your tank falls over that transmitter will snap like a twig if it hits anything
