I've dropped my meter in a mtn creek a couple of times on long backpacking trips, had to estimate
the exposure for both b&w and color trans and got perfect exposures. But that's only because I've
metered analogous lighting thousands of times and my memory worked for once. Since I work primarily with 8x10 film the thought of bypassing a meter would otherwise amount to insanity. Film
that size isn't for machine-gunners.
