Depth Finder Question?

you can take the screen off and dry it out. Take the screws out of the back and it will pull apart. Easy!

I think that kind of depends on the brand and process used to fill the unit with inert gas.

You may have cracked something in the cold temps that let the moisture in. maybe to sit out in the sun and warm up for a few days and let it get hotter could help.

as said above, you can take the screws out of SOME units and get to the screen. other units you will tear up even taking out the screws it will only let you get to the c-board. best thing to do is get a plastic container with a top, loosen the screws on the back of the unit until the rubber gasket is loose and movable. put the unit in the plastic container with the back loose as described, and place some UNUSED charcoal in the container as well and sit it out in the sunlight. the hydrocarbons will readily bind great to the moisture. even after your screen is nice and dry, leave the unit in the box for a whole day to make sure all water has been absored from places in the unit you might not be able to see. this trick will work for any electronic items that have fallen into water or have moisture as long as they have not been powered on and shorted out. great for drying a cell phone, rod lockers, all the lockers in your boat when storing for the winter (just so i dont get an odd email) put charcoal into old socks and tie the top of the sock so charcoal does not come out. then put into your boat at desired location. cheeze cloth works well also.
hope this info helps someone.
