I got in the pool today with the Venom ARC.
It does not seem to be a great fit for my face. Sometimes it leaked like a sieve. Other times, it seemed like I got a perfect combo of mask position on my face, strap position, and strap tension, and then it would go for a while before I had any water to clear.
I did not have any issues with fogging. I cleaned it thoroughly with Dawn dish soap last week. I put diluted baby shampoo on it before I got in the water. I'd say it was a pretty good test of fogging today, too, and I was on my rebreather. That meant I was breathing out of my nose a lot to vent the loop when I would ascend. I was swimming around practicing buoyancy, so a lot of up and down. With all that exhaling through my nose, I think it would have fogged if it were so inclined.
I'm going to try it on at least one "real" (i.e. non-pool) dive before I give up on it, but right now it does not look like it will be a keeper for me.
I ended up getting a Seadive Rayblocker.
I have a DGX Ultraview mask with what they call an ARC that looks very much like that. Well, I had one. I can't seem to find it right now. But I digress...
DGX Ultra View Anti-Reflective Mask
To me, that is not a proper ARC. I don't think an ARC should have any kind of tint. If you can see that it is changing the color of the light, then that means it is reducing the amount of transmitted light, at least in some part of the spectrum. If the outside is reflecting some color back to the outside viewer, then that is visible light that is reflecting instead of letting it pass through to your eye. I.e. reduced transmission of light to the diver.
I have seen eyeglasses with ARC and I have some framed art that has glass with an ARC. All of those are perfectly clear. You can't tell that they have an ARC except by the fact that you don't see ceiling lights (or windows, etc) reflected off them like you would if they did not have an ARC.
The Venom ARC seems to be "like" those eyeglass coatings.
I'm not knocking the ones that appear tinted. In bright ambient conditions, that tint might be advantageous. But, if I were, for example, inside a wreck and just wanted the ARC to eliminate reflections on the inside of my mask from dive lights (reflecting off the skin of my face inside the mask), I would not want a tint that is reducing the visible light transmitted through the lens and into my eyes.
(I wish I could find my DGX ARC so I can compare it to the Venom)
