Thanks for the photos Johan . Has the new 02 block done away with the loop of hose and hose clamps that were on the old type?? Also how do you find diving with a needle valve? I am thinking of putting one on my Kiss.
No probs :-)
Yes they are gone. The new block is a lot more clean and has a very professional look to it. (Hey, Andy, u know where to send the cash...)
We'll I'm pretty new to Rebreather's, but I realy can't find any dissadvantage of having a needle valve.
It's nice to be able to fine tune the flow to a level just below your current metabolic rate and then be able to change it when the conditions of the dive changes.
So far I pretty much leave it on the same value during the bottom phase and increase it slightly when I start the ascent. But I haven't donne any realy challenging dives so far.
It's also feels safe to be able to change the flow during the dive in case of some dust or paint-flake, obstructing the flow of O2 thrue the needle/orifice.
Go for a needle valve
