Hallo to all. I am looking for a good impermeable or underwater clock with voice recorder function, even like that one of the cellular phone, where you click a button and it register, but I can't find it. I bought something like that, the casio DBV 3000, but it wasn't impermeable . I bought a chinese one too, it says "water resistant", but when you go under the water a few humidity passes and the contacts are oxidized therefore it doesn't works anymore. Anyone knows a truly impermeable or water resistant model? Any suggestion or link? Thanks to anyone that can help me.
