With this configuration I have no problems with movement in any direction
Now there a few problems I have encountered, the mask still had the gas
path over the visor then into the nasal cup which works ok but if you had
any resistance on exhale you get a back pressure which pushes bad gas back
over the visor and starts a co2 loop, I took a hit about 4 weeks ago so can
tell you its not pleasant and even if you bail to o/c on the mask it dose
not help as the problem is still with you in the mask.
To stop this I have blocked the gas path over the visor and removed the
valve in the centre of the conversion (seen in the first picture) then you
need the reverse the valves in the nasal cup so the mask still equalises.
I find that I can not run min loop with the mask as it becomes uncomfortable
when you inhale so I run a little more volume,
My only other problem is my face! And the mask vents to much gas but I have
a fix for it, just need to get around to fitting some special neoprene to
I can still get the parts for the original conversion to the mask but the
part I made for the nemo dsv was a one of the kind but a number of people
have asked me to make more for the nemo and a few for BOBís
So I may be persuaded yet.
Kind regards john routley
Ps I donít have any more pictures of the parts I made but can do some if you
This is the mounting plate I made, this bolts straight on to the Nemo dsv
and on to the AGA conversion made by Gil
Knott of Saga Ventures LLC.
I didnít use Gils original conversion as his convertion is made just to take
a standard dsv not a oc/dsv which is much heavier and I was worried that it
only used one wedged o-ring to hold the dsv in the bayonet fitting
So I got from him a blank bayonet fitting which would normally have a
machined hole in it for the dsv bitewing
