In Topic: GoPro Hero3 buoyancy?

Can you weigh it with a spring scale in freshwater, then do a density conversion for saltwater?

For what it's worth, that is exactly what I'll do when I get it, if nobody here has a ready answer (you can tell I have too much SI between days I can dive) :)

My guess is it's definitely negative. Knew a guy who had a Hero 2, dropped it on a rocky beach in slight surf (all housed of course) while putting on fins to swim out to the boat, and it was swiftly gone...churned out from shore by the undertow and never seen again.

Oh, I agree that it's negative (they make a foamy float attachment for the housing for watersports uses). I was hoping someone knows whether it's 100g negative, 250g, etc. I'm trying to get fairly precise numbers for a scooter rigging, and getting it into the ballpark early on would help out.
