Considering my P2 is sitting at the bottom of Convict Lake in 140' of water, and the fact that I do lots of surf filming, it would be great if the birds would either float and have the ability to seal up. If all that is too much, just allow the GoPro or P3 camera to eject itself and float to the surface somehow so at least I can capture the video.
Oh, and add a tracking component so we don't have to buy external GPS units and strap them with Velcro. Mine started looking like a junkyard with all the "extras" strapped or screwed to it.
