The strips work excellent. But they do need to be recharged by baking them. A fellow kiter around here is some type of hydrologic engineer and he had to do the same thing all the time with desiccant strips on his equipment.

In Hood River it was so dry I never needed them on my GP2. At home, I need them all the time. 5 minutes in the oven and they are good to go.

The putting the camera itself in the fridge is because modern refrigerators dehumidify the air inside of them.

I've tried the strips and they don't work worth a crap. At least for any of the places I've kited with the GoPro. (Hatteras, Bahamas, The UP, Wisconsin, etc.) I was ready to throw my GP in the fricken trash. That thing ruined more footage and just pissed me off. I'm convinced it's not location/humidity, but some of the housings were bad. I talk to some guys that never have the fogging, then myself and others have nothing but issues.

So last ditch effort, this fall I did buy the GoPro dive housing while in Hatteras. I haven't had ANY fogging issues whatsoever. I used it all week. Then while home I used it kiting in November on Lake Superior and mountain biking in 25f degrees and I haven't had any fog. I now officially like my GoPro again!

So I can't answer Tob's question on the GP3 fogging, but the 3 has a lens shape/style that looks more similar to the dive housing's. I'm hoping this resolves the fog issue.

If GoPro would like to send me a Hero 3 Black Edition to "test" I'd be happy to!
I need that WiFi and remote!!!

The addition of the Wifi bacpac & remote to my HD1 has fixed the fog issue for me.
With this setup, you just need to remotely switch off the cam on a regular basis (5 mn off every 20mn for instance)
By applying this simple tip you can take pic or movies without any fog for hours...

follow the instructions.

cannot comment on hero 3 but this works for hero HD 2 hero HD hero 960p and Hero.

preheat oven to 300-350F with a cookie sheet in the oven already.

put two strips on the cookie sheet for 5 minutes after the oven is preheated.

immediately put the strips in the camera case and seal the camera up. Do not let them cool off first.

This works every time for me but I must stress that you have to do this EVERY TIME YOU USE THE CAMERA.

Also if the strips have been sitting in the camera for several days you will need to reheat them again regardless of if you used the camera or not.

Polycarbonate (what the camera housing is made of) absorbs moisture. The strips will soak up most of this but if the strips are already saturated the case will fog as soon as the camera is on long enough to heat the moisture inside to a point of condensing on the lens.

Hope this helps.

If this hasn't already been said, do make sure you clean the o-rings, and make sure there is no sand or salt encrusted on them. Letting the camera sit in the sink in fresh water for a while after using the camera helps to avoid this. A dab of silicone lube to the o-ring will keep it in good condition and help keep out water that might be seeping past the ring, and humidifying the inside of the case. Also examine the pass-through button o-rings for signs of grit and get in there with some lube.

If the strips are not working, there is some seepage going on, without a doubt. I use my GoPro 2 in Florida, the humidity capital of the friggin world, and I never had an issue or needed strips.

Another issue that can cause fogging is taking the camera out of your air conditioned car into a warm environment.

Also you can treat the inside of the lens with Rain-X Anti Fog, which you can find at Wal-Mart or any auto chain store. Normal Rain-X works great for the outside of the lens, so you don't get that water drop that hangs in the middle of the shot through 20 minutes of video. It's great for your sunglasses, too.

What I have tried...

Anti-fog strips & sprays, blasting the case with cold (dry) air from the car a/c and even putting a piece of chamois on the back door.
Mixed results. Sometimes good, sometimes bad, sometimes bearable.

Other guys store the camera & case in a plastic bag with desiccant then add the strips and a/c blast the case and camera and claim it works. For all that bloody effort, it makes it an annoying gizmo to use...

I bought a Contour ROAM2 recently, should arrive today. Waterproof enough that it won't need a bloody case and shouldn't fog!!!

If it wasn't for the fog, I would have bought a GoPro3

All that crap is not necessary. I bet you have a seepage problem. Try cleaning and lubing the o-rings and Rain-X Anti Fog. I bet you it solves the issue.

Also what I had in mind. HD2 was fogging just on the lens, and ussually just from one side, because it is quite exposed bacause of it's spherical shape. If I have it on a tripod (stationary) it is fogging on the upwind side. Otherwise in the winter can get really nasty.
New lens shape could be a + in fogging issue.

Hi. Poacher I've a question for you. Does the Go Pro Dive Housing reduce the field of view? Thanks in advance.
Best regards.

I have cured this by packing tissue around the edge of the camera and at the back and blasting the case and camera with a hairdryer before closing. Rain x on the front of the lens sorts out the droplets a treat.
