What a shame!
And I suppose the altimeter works on air pressure so you can't even put it in a plastic bag.
I wonder if a gore-tex bag would work...
Actually, I suppose a slack plastic bag would probably transmit pressure with no problem.
Oh. Hmm. I think you're right about that.
And the water pressure won't matter because it's the *lowest* pressure readout you're interested in.
Maybe that's worth trying?
Oh, forgot to log in. That was me.
