So on my sled I mounted my HDS8 on a ram mount near the transom of the boat. Well after a pretty sloppy run out to the banks this weekend I realized that with the combo of wave spray and rain that it actually gets pretty wet. Now after every day I take it inside and wipe it down with a damp towel and let it dry. After a couple wet days on the river and a pretty brutal trip back from the straits I haven't noticed any water in the casing or anything but I've heard several stories of water problems with the HDS units.
I was seeing if anyone had thought about this or if I should even be worried? I've thought about buying one of those visors they make and then bonding on some heavy PVC to the back side. Build kind of a cover for it to try and keep the water off of it.
