I use 500 psi for Freediving and Spearfishing in Southern California. Water temps 55 - 75 degrees.

I clean the mask with filtered drinking water, dry with a towel using fingers, then apply a dab of the gel to my finger and use it to smear a good gel coat on the inside of my mask. Then let it sit for a short time while I prep my gear. Then I use a small amount of filtered water to clean the gel off the inside glass by very lightly swishing the water around and use my finger if necessary. Swishing the water takes most of the buildup away unless you used too much. Leave the inside of the mask wet until you put it on.

Works for me almost all the time. I have had the mask fog a few times but that could be my fault. Keep it on you in a small pouch or bag...you CAN re-apply in the water using the same method. Just make sure to rinse after applying otherwise the evaporating may sting the eyes when you put the mask back on.

The little bottle will last quite a long time. You use a very very small amount each time. This will last you at least an entire season unless you really overkill the amount used each time.

I have not tried this in the pool. If I do I'll update.

Tried them all and this works best for me. I'm a diver and a fogged up mask will ruin a dive. I use alot of it. I probably don't have too but I'm not taking a chance on a fogging mask ruin my day when I've already loaded all my gear, put gas in the boat and drove to the lake. I wet my mask and then put a quarter size amount or more on each lens and rub it in. I then let it set, and then put all my dive gear on ( which for me can take several minutes) and then get in the water and rinse the mask a couple of times and go diving. This method has never let me down. I dive for usually 5 or 6 hrs. each trip and I never re-apply. One thing though is if you don't completely rinse it all out and I mean every bit it will burn your eyes. I've done this on several occasions (which is my fault) and it has burned my eyes on up in the night. It's not unbearable but it does burn. Probably a rambling review on my part but maybe it will help.

I've been using this stuff for over 30 years and nothing, and I mean nothing else I've tried even comes close. Keeps my mask fog free even with continual nasal exhale.

It worked well enough. Had to reapply after every dive. Make sure that you use fresh water to rinse before you use, The chemical could be uncomfortable.

I'm a scuba instructor, and have used just about every defog available. This stuff is the best. Its much more expensive than spit, but works better!

I tried quite a few antifog solutions and this is by far the best product.
I borrowed a drop from a friend once and got hooked.
I live in Europe and find it unfortunate that purchasing here is so difficult, perhaps the free trade zone will help us here in the future :-)

Have tried this product before and will continue to use. When applied as directed, helps to keep fogging out of mask.
