Do not let the camera get wet!
I fished a lake from a metal dock that slowly started to sink not having been secured yet by the park. Bad enough my shoes and small tackle box started filling with water but also the bag that
my digital camera was in. The camera was off but the circuits were destroyed and though it functioned a little after I got home, next day - nothing when it came to the controls or preview screen. Luckily I have a spare but ordered the same model-used, on eBay for $21, shipping included. Hopefully exterior defects are the only ones.
