Fogging of housing - any solution?

[Asher Ang]

Hi all,

My Olympus PT-059 housing recently started fogging. I know about the usual solution, temperature, insert desiccant pack, etc.

I am wondering, since the housing wasn't prone to fogging in the early days, could it be something to do with degradation of the coating at the inner lens surface, some scratches even?

I like to know, if there is a solution involving coating that can be applied to the inner surface, to prevent this fogging?

Thanks for reading.

If it only recently began fogging but previously did not then most likely it is seeping a tiny amount of water somewhere. I had one of the old Canon cases that did that. I bet it would fail a pressure test.

However if the fogging is due to a change of diving environment causing it to now fog you can try the Moisture Muncher desiccant tubes or packets. Just google Moisture Muncher.

The proven way to prevent fogging is to seal the housing with 0% humidity air. Like in your tanks. Get a small dust nozzle for your BC hose and GENTLY blow dry air into the housing with the door closed around the nozzle. SCUBA air has a dew point of -50 degrees.
