mine works fine, it must be user error, you should be working on your trim and not the BOV.....

I guess I should remind u that proper trim isn't verticle with your knees dragging through the wreck....

I'll five it a few more test dives and then try it at depth.. So far it's lookin promising. I have noticed the shape and length of the tongue changes the sound of the inhale. I'm going for the quietest as my guess is the quieter is is the less swirly gas goin on in there

No excuses at the boat ramp then...

So what's the cost of the mod, if one supplies a card for use, say, a PADI OW cert? Or better yet, OWSI...

But I'll fail if I don't float up when holding my breath, or grab hold of the lead weights! Woe is me! Oh, the humanity...

(can you guess we have 3 hours 10 minutes of term left?) (2 weeks holidays and Hong Kong, here we come!)

I tried my bov mod on the weekend... At 45m it breathed awesome on the inhale!!! No gas went out the exhale on inhale ( if that makes sense)
Only issue is the exhale now.
So my next trial is a softer mushroom on the exhaust and widening the hOles in the orifice to increase flow.. But afaik it is working great with a noticeable difference

I reckon your deflector is too big Rob have a look at the gas deflector on say a apex tx40 it just sort of wraps around the gas barrel with no restriction to the exhaust valve (except for gas direction)
