Go Pro Fogging

[Lizard Leg]

SRP BlurFix with SWCY filter - once the lens is cleaned, I hold the camera in front of a window A/C on full blast - fill it up with cold, dry air, and put the lens on quickly. Hold the housing and let the inside fill up with air for 1-2 minutes and put the camera in and close while still in the air stream. 2 GoPro dessicant strips, one on each side. As soon as you get on the boat, put it in the camera bucket. Never fogged in a week of diving and never had to take the lens off - it's actually still on from that trip and until I need to change the red filter out, no reason to take it off!

2 things....make sure you submerge your camera in sea water (Bucket or something) for a while before you hit the water. Major temperature change is a culpret to fogging. Next you can find GP anti fog inserts that work great.
