FFM fogging, need antifog coating

[laguna230diver]

After i decided not to sell my scubapro FFM i decided to sea buff it... BAD MOVE

the antifog factory coating is removed now and im having a mask fogging problem... any known fixes?

500psi wasn't working.. any advice? anyone know if i can get the lens recoated?
thanks

No, really, I had a friend that was on the US Olympic luge team and they use to wash their face shields with a certain shampoo. You might try a light coat of baby shampoo before each dive.

I use SeaGold in my scuba mask and it usually lasts for a full day of diving.

thanks mud! Im trying my best not to be embarassed of such a stupid move... its not working yet lol

i've heard good things about seagold.. do you ever have any fogging with your helmet?

 

[laguna230diver]

i know its gimmicky, but i've even been thinking of magnetic mask clearers (like a fish tank algae remover)

Commercial masks and helmets have an air train (pipe with holes in it) that shoots air over the face plate when the diver opens the free-flow valve on the side of the mask/helmet. It serves two purposes 1) it de-fogs the face plate, and 2) it vents the hat to remove any excess CO2 build up. So there is no need to de-fog the face plate on a diving helmet.

If the face plate does start to fog up, it is a good sign that CO2 is building up inside the hat and that the diver needs to vent. :shocked2:

i was just clearing the lens by looking down and moving around a small amount of water... after about an hour then lens was getting clearer on its own, is this possibly a temperature issue? Or could it be a CO2 issue as the bulk of my energy expendature is in suiting up and the first parts of my job? any help would be great! I have a pretty nice mask that could be a LOT better.

thanks!

Just looking at the Scubapro web site and can not tell how the inside of the mask is configured. It states that there is a separate for nose and mouth, but I can not tell if it is like the oral nasal on a commercial mask. Most commercial masks and hats (if they have a demand regulator) have a cup that your mouth and nose fit in to reduce the area that you exhale into. This reduces the CO2 build up and dead space in the mask/hat.

Your fog problem is most likely the difference in temperature between the water and the inside of the mask. That is the same reason a scuba mask fogs up, plus the moisture from your breth as you blow out your nose to equalize the mask.

I dive a Kerby Morgan M48 Supermask and it uses an internal mouth peice like a normal scuba regulator to reduce the dead space that the dive exhales into. I get some fogging with that mask if I don't do a good job of applying de-fog before the dive and I end up breaking the seal and letting water in to swish like you said you have been.

i used to dive this mask with a mares abyss reg that had a long stem for the mouthpiece to attach too. right now with my apeks regs, the thickness of the FFM is too large for me to get a mouthpiece on the reg inside the mask. As for the "seperate pockets" i think the only thing it successfully does is keep any leaked water off of my skin. The inside is not sufficiently separated. Thanks for the advice!

I guess for now I'll try more de-fogs and if that doesn't work... well ill get to that when it comes

There is no oral nasal on this mask like a commercial band mask or hat has. It is like a blinged out model of the old Cressi mask. The SP is very nice, but limited because of the lack of oral nasal and CO2 buildup can be a concern during dives.

all i can say is thank god i got it for cheap
