I'm on the Gulf Coast and have similar interest in salt air longevity.
My WS-2902 is just a couple of days old. One obvious area of concern is the battery compartment. Once I installed the batteries, I gave it a good grease packing before re-installing the cover. Hopefully that will slow corrosion in that area.
