Yep, water and electronics/gears don't mix. VERRRRRY quick action by competent tech could have saved the gear. I work on electronic stuff every day cleaning corrosion and other "stuff" from aircraft avionics and re-protecting it. NOTTT an easy task. Our crews pour (accidentally) coffee and cola into them, that's worse than water. [:'(] First step is prevention and then you have to act quickly if it does get contaminated.

Another of my favorite sayings: When they develop a better idiot proof system, someone will develop a better idiot to screw it up.

Just protect your gear as best you can and keep it as dry as you can. if it goes in the water-get it out as quick as you can and dry it quickly. If you feel competent to do so, remove the covers and GENTLY blow compressed air to dry. Be sure to hold the nozzle with your hand to try to reduce the static charge on the air from the nozzle. Use dry Nitrogen if you can find it
