GPSMap 78s and humidity problems with unit
I am using the GPSMap 78s on my kayak out to sea but currently using my 3rd unit due to water getting inside the unit over time. The first were replaced after about 5 months of use. Is there a way to dehumidify the unit after each use or a type of gadget that I can buy to do this? Leaving the unit in dry rice for a week or two sometimes sort the problem for 1 or 2 outings but then starting giving problems again with the buttons again, either zooming in and out or switching on or of.
