Waterproof Digital Scale?

Does a waterproof digital scale even exist? I have a Berkeley digital scale but it got splashed and now doesn't work. I might have had a new PB largemouth yesterday but the scale was broken. I know electronics and water doesn't mix but I'm not fond of the pocket scales that most places sell as I've yet to find one accurate enough for weight that doesn't exceed 10 lbs, even then they can be off a half a pound.

You Tube something like "Homemade balance beam scale" - go real old school with a couple of sticks and a sliding weight?
