I can do the dive and deco just with the HUD, Not on 15.5
Quadruple redundancy of reading ppo2, just double on 15.5
Boris will keep me more alive with his Alarms messages than a 15.5
I can mechanically isolate Dil or O2 if ADV or solenoid kaput and still add manually gas w/out having to open/close the tanks for 4h deco ! not on 15.5
Yet all of these features can be retrofitted to a Mark-15 in one way or another... either by an electronics package change or some faitrly simple pneumatics mods.
Mark-15 is far more field maintainable, and in the long run, my bet is that they will still be in service long after the 'Boris is a curiousity.
Think of the divers who "upgraded" to a CIS... and now the CIS is passe', but the Mark-15 is still an icon. There's a reason for that.
