I just had a look, and they look really nice, has anyone actually used them in anger?

I currently use Apeks nipples on all my kit (inflator and drysuit) so that I have nice chunky disconnects, but this may be a better solution.

Cheers

For the tight arses amongst us, another option is a small hose clamp tightened around the end of the fitting. It offers a chunky bit (the worm drive screw) that is easy to hit with your thumb and yet still has low profile edges to fit easilly on wing inflates etc.

Im beginning to think I've earnt this "luddite" label.

I have got to say I find it quite interesting that everyone that has replied opens there valves only a small amount!

From my new to rebreathers (a kiss) perspective the thing that scares me most is low ppo2. So to my mind if my valve is full open I am going to have less chance of bumping the valve closed and probably more relevant to the dil, better flow at depth. The downside is it takes longer to shut down, but once again as a newbie my modis operandi in case of doubt is flip that oc dsv switch.

Mind you, I guess that my mindset comes from years of diving oc and not having a reg free flow or hose burst under water.

Looks like there is a ccr mind set that I haven’t quite got yet!

Interesting

One thing to rememberabout oc is that you are constantly breathing off the reg so you are controlling the IP.. If you have IP that is creeping on OC you may never see it, but on a CCRyour first indication can be a blown hose or gas bypass into the wing or counterlung(s)
