Seeing is believing

By Gregor d.

The 500 PSI antifog works well and is good for multi dives before an additional application is needed. Much better than the "more liquid anti fogs out there.

 

Excellent defog

By diver h.

We used Sea Drops for years but have become dedicated users of 500-PSI. I have always had issues with other defoggers esspecially when used during cold water (50 - 60 degrees) dives. It seemed that no matter what we used my mask always fogged somewhere, somehow. I now use only 500-PSI and never have any problems with fogging. From warm water to really cold we think this is the best defogger yet.

500 PSI Mask Defog is without question the clearest, longest acting and most effective defog on the market. One application works for at least three dives in one day. Cleans your mask each time you use it. Wet or dry application, has the consistency of extra thick toothpaste, and when applied to the lens typically lasts all day long. 500-PSI Mask Defog comes in 2 or 4 fl. oz. (59 or 118 ml) size with a 2 fl. oz. (59 ml) available with a carabineer clip.

Questions & Answers

Questions about this item:

Daniel R  Is this now a spray? What happened to the old style squeeze bottle kind? Is it as effective and does the bottle last as long?
Donald R  Bottle I purchased was a thick gel that had to be squeezed out.
YAN G  This is a squeeze bottle.
ROBERT P  The defog I bought was not a spray, it was the same old squeeze bottle.
Shopper  Why Did You Choose This?
THERESA M  Because I need it
ROBERT B  Great defogger, but you need to make sure any dirt, salt residue or suntan lotion is cleaned off the lens before you treat the surface. AND you need to make sure you rinse the lens with salt water very well. If you can see the defog on the surface of the lens, there is too much and needs to be rinsed better. Also, we found it best if you treat the lens just before you go into the water and thenm rinse them. Don't let the defog dry and then try and rinse it off.
MICHAEL O  I've been using 500 psi for over 10 years, as an instructor, a diver, and at the local aquatic center. I recommend this defog highly.
ANDREW M  Because I've never used anything better
Paul M  It works where others I have do not.
Douglas C  Recommended by mask manufacturer
Ralph G  It cleans and defogs . Also it lasts for 2 tanks
WYATT H  I've found it to be the best I've ever used.
GARY S  recommended by dive instructor
JENNIFER P  The BEST mask defog I have EVER used. I have NEVER had my mask fog up on me.
PAUL B  Duped. Never again.
PAUL B  Stinks. Came free with a bag. Never by this product. Seafoam or Seadrops are the only way to go if you buy the stuff. Baby shampoo does a better job and won't burn your eyes.
MATTHEW O  The only defog worth using. It costs a lot because it works. Yup it's expensive so buy the big bottle if you're going to do more than 50 dives
TRAVIS K  Waste of money, I keep the same little bottle with a few drops of "Dawn" dish soap and water. Then it doubles for making drysuit seals easier to pull on.
