Thread: Fog in screen

That's moisture ...

Put the unit in a bag of rice for several days ...(with the SD Card card slot door open) ...

I've never had to do it but I have read where the rice trick works. Of course that is uncooked rice. Certainly worth a try. Let us know if you do it and how it worked.

Scrat, I could be wrong but I think your card door could be where you picked up some moisture. I read where some units had no gasket or bad gasket around that door. Do what Rickie said and you don't have to bury it in the rice. In the meantime I would call humminbird about the seal. I know they sent some guys a new yellow seal for map card doors.

Thanks for the feed back on this problem. I put it in a gallon zip lock bag and put instant rice covering it. I will leave it there for about 4 or 5 days and see how that does. I will post back later after I try it out then and let everyone know if it works.

I too have had this problem with my Humminbird. Standing by to see if this works for you. As far as I know mine does not have a map/SD card door. So not sure where or how the moisture is getting in.

I dry my electronics in my food dehydrator. I just set it on 95*F. I had fog in my X47 and I just stuck it in the dehydrator for 20-30 minutes. Walla. Never power anything up when you see moisture. Just a warning. Bad part about moisture is the corrosion of the circuit boards. They will corrode.

I repair electronic circuits on occasion. After repair, I wash them down with soap and water, rinse them off and pat dry, then stick them in the dehydrator. Of course, I ain't scared to do this like most folks.

Dehydrator works good on deer jerky too.

I usually keep my units stored in my gun safe that has a dehumidifier. If not I have a plano pistol case that will hold them and I save all those little silica packets that come in most everything you buy to put in there with them to keep down the moisture.

Well I put the HB 581i in a bag of "instant rice" on 3/4/16 and left it till 3/14/16 that was 10 days it stayed in the rice. When I took it out on the lake I did not see the fog in the screen so I would say it did work. I did leave the card slot door off but will put a piece of cotton or screen in front next time if needed as the rice did make it's way into it and took awhile to shake it out. I thank Rickie and everyone else here for your help.
