When any or all the suggestions fail, you might consider an Olympus Stylus water proof, shock proof, idiot proof and ????? proof cameras.
The guys in our family are kayakers, boaters, fishers, bikers, hunters, hikers often in terrible weather.
Our Olympus Stylus 1050 SWs have survived water, rain, drops and other horrors and keep working.
My 1050 has been in rain in a driftboat, jon boat and a big power boat all day or waders/shirt pockets, and it has been dropped several times and still works.
We use the Olympus Floating Strap #202204 that sells for $20 to keep them floating. My floating strap has saved my camera a couple of times. The cameras will sink if dropped in the water without the little life jacket.
We put the Always On Red Neoprene protective camera cases on the cameras to protect their outsides re dirt, mud, crud and scratches. You unsnap the velcro, and the cover unfolds for a quick shot.
