CONDENSATION ON CAMERA LENS
Mark,
Condensation on the inside of your camera lens is a function of the moisture content inside the camera having a dew point higher than the temperature of the lens.
When you put the unit in the water the temperature of the lens will eventually go down to the temperature of the surrounding water. This is like having your windshield fog inside a car.
there are two ways to solve the problem:
1.) Add heat somehow to keep the lens from getting so cold.
2.) rdeuce the dew point of the are by drying it out.
For solution 1.) you would need to have some form of electric heat, say a resistor, but it gets a bit complicated in terms of making sure you do not over-heat and damage the camera. this would also add a load to your battery pack.
For solution 2.) you need to be able to open the camera and purge it with something like compressed Nitrogen (that will have no moisture in it) or compressed air that has been dried out as part of the compressor system. Then you would need to immediately seal it back up. Alternatively, if there is place to put dessicant dryer packs (the kind you see inside medicine bottles for instance) inside you could do that and then seal it back up. You can not count on using an already opened dessicant, so you would have to get brand-new ones.
Keep me posted and let me know what you think you can do. Also - you can always text or call me at 631-316-2193 if you want faster feedback.
