That's it, snapped the darn Navionics micro card in half playing around. Yes, I use dialectic grease also. Going to try a different tact, use a
Samsung Galaxy S3 Mini GT-i8200 Factory Unlocked International Version for speed and GPS with the Boat app from Navionics. Put in a
Ultraproof Waterproof Case for Apple iPhone 6 5S 5C 5, Samsung Galaxy S5 S4 - [Black] Universal UltraBag Waterproof Pouch with Touch Responsive Front
, placed in a Railblazer holder, in place of the Lowrance. Also I will go with a
Humminbird 407860-1 HDR650 Digital Depth Gauge , waterproof, up to 600 ft, probably half that in salt water.
Let's see if I can get more than a year out of this configuration.
