The MK15.5 is the direct descendant of the MK15 and the CCR-1000 built by BioMarine Industries. In the 1980's a diver for Shell used a CCR-1000 on a dive of 1,800 fsw (545m) out of a lockout chamber
Pros
- its designed for deep dives (recent dives to 220m, 175m, 185m, in 1980s 545m)
- it has long scrubber life
- it has back mounted lungs so chest is free
- extensively dived by US Navy (still used)
- compact and streamline
- looks r e a l l y cool
Cons
- its no longer manufactured
- hard to find one for sale
- Parts are hard to get
- expensive to buy (US$10 - 15k)
- it has higher wob than newer designs
- need to update controller
Think of it as an E-type Jag, whereas the capable inspiration is more like the new S-type.
