Right, whilst we're here talking about UTD, someone's
just posted about a
UTD "Z" sidemount system. What on earth is that all about???
Sidemount's about as simple and reliable as you'd ever want. Sure, it's a bit fiddly to get configured to your exact sizing, but once over that, it's superb. I just don't understand why anyone would want to complicate it by adding a manifold. Sidemount's pretty much standardised to a short hose to bungeed necklace on the LH cylinder and a longhose around the neck to the RH cylinder. The only modification from "DIR" would be the use of a break-away O-ring to secure the longhose boltsnap -- so you can pull it off your RH D-ring when breathing from the other reg.
Anyone know why they add a manifold and another valve behind your head, when the two cylinders are perfectly happy beside and in front of you -- it's a hell of a lot more accessible than getting to the valves of backmounted cylinders!
