why are you getting rid of it?
My whole rig is set up DIR, and was going to use the same rig for re-doing my class, which I took a few years ago, for Cavern. I was going to also do full cave, Intro next, and use the 6' hose for my single tank for cavern, and my 7' for my doubles, and take the intro to full cave in doubles, even though I'm all ready Intro certified, but I been out of doing the cave thing for the past several years, and If I was going to get back into it, I bought the 6' DIR hose , with there hose kit, SPG and inflator hose.
I decided not to get back into the cave diving for now, because it would require me buying alot of gear that I had, and sold, all over again, and I just invested over
$7K into a DSLR set up, and am looking to get CCR rebreather certified next spring, I'm currentley SCR rebreather certified on two differnet units, and owned two of them.
Hope this helps, good luck with your class
