Nope, the ACB pockets are not DIR. It's one of the few Halcyon products that isn't DIR.cys:Are ACB's DIR? They are sold by Halcyon and use plastic buckles.
SeaJay:Did you try your TP with the optional crotch strap? I did, and it seemed to take some pressure off my diaphragm.
ElectricZombie:Nope, the ACB pockets are not DIR. It's one of the few Halcyon products that isn't DIR.
Atticus:A somewhat related question...
I dive a halcyon BP&W and have keepers installed such that the shoulder portion is a fixed length (keepers behind the backplate which prevent webbing from moving from the shoulder loops to the waist loop).
Some friends dive without the keepers so they can unbuckle the waist strap and enlarge the shoulders for donning/doffing.
The left waist strap has a D ring installed (stage bottle ring), so it cannot slide out more then a few inches. The right waist strap has the light and extra buckle which holds the light in place, so it too cannot slide out more than a few inches. I really can't see the rig "falling off", which was my first concern.
I haven't removed the keepers from my own rig, but I've considered it.
Comments?
cys:I agree, FWIW. I just didn't want people to forget that Halcyon sells something with plastic buckles.
ElectricZombie:I've seen them break before; it can and does happen. Those plastic buckles are tough, but they do break on occasion.
I don't see the point of introducing potential failure points. It would be different if the buckles offered some sort of advantage, but they don't. I can get in or out of my gear as fast or faster than someone with quick release buckles. Why add something if you don't need it?
-hh:You can also make a similar case about "QD" wingnuts on STA's on many popular backplates today...the fallacy is that if the objective is to have a system that tolerates being harder to adjust, but doesn't need to be changed once adjusted, then going from singles to twins should require two dedicated rigs so as to eliminate the detachable STA. The normal wingnut defense is to point out that they're made metal instead of lowly plastic, but that's bogus: a materials change does not eliminate a failure point. We can also say that wingnuts are tough, but they do break on occasion too. Ditto for anything else that have threads that can be stripped.
