Hi Matt,
The Cis does have an ADV right ? Why didn't the ADV inflate the back-up unit on descent ?
Yes, you are right, the Cis does have a ADV, sure enough, its located in the counterlung. Mhhmmm. Don't remember why it did not inflate. Maybe it was not activated .... can't remember, memory lane is not that bright today.
When developing the double units one of the earlyer designs had one unit on the back and the second on the scooter. Looked good, only problem might be that if you have to ditch the scooter, the unit goes too.
While on a trade show in Germany two years back some guys showed a refined RB80 copy ( Deep Access ) presented as a double unit. Looked like a set of alm 80 doubles on the back with two sidemounted tanks for dil and o2. That looked pretty good.
You could to the same with almost any ccr I would think, just buy two ( happy hour ), mount them side by side and see what gas and tanks you need, bracket mounted to the unit and / or side mounted.
