I need to buy 4 x GoPro2—-and maybe 10 more later
Drilling holes in the plate will help to prevent it flipping!!!!!
my frames already work fine* you crazy bear! now put your head back to the wifi/attached gopro/ sending a single picture/framegrab back to the boat easily problem 
* although at 50kg they are too heavy- problem is though if they aren’t heavy they drift in strong currents or a big tiger shark comes along and grabs the attached bait canister and swims away with the cameras and I come back and the buoy on the surface is 1km away and still racing away haha
we bought a whole lot of the Gopro2s yesterday…...Also Thanks everyone for the ideas etc, feel free to keep them coming. you never know what ideas could be the next thing to become standard practise.
reasoning: GoPro2 specs are equivalent to the silver edition not the white, ETA on batteryback packs and lcd screens for gopro3 was unknown and the gopro2s we have already do exactly what we need so there isn’t really any reason to spend more and upgrade. I did try and sneak on one gopro3 black to the order but my excuse they we needed to do some research in ‘snowy’ and ‘surfy’ conditions wasn’t accepted
Pretty sure the current LCD BacPac fits the GoPro 3!!!!!
that is confirmed old screen will fit new gopro3
GoPro’s are only depth rated to 60m’s if your dropping them down to 100m you might have some problems.
I do trimix diving in the 50-80m range and ive never been game to take my go pro so would be interested to know how they handle the extra depth.
If i reading your previous posts correctly your just using the gopros as a check on your camera mounts and your retrieving them once the mount hits the sea floor then a lcd backplate would work fine as it allows playback.

Wow! That’s deep!
Welcome to boardworld, DR. 
what is the rough coast of that cat6 cable? remembering it needs to be approx 100m long?
Cat6 isn’t very expensive you can get 100m for under $50. Keep in mind 100m would be just about the maximum run you would want to do with cat6 without boosting/terminating the signal. That’s where fibre runs come into play in traditional networks.

There seem to be some aftermarket cases that go to 100m.
We sent one down 100m and it came back up fine. I wouldn’t recommend it though, especially if you have one Gopro. we have stacks on them so thought it was worth the risk.
In the end it might just come down to having to risk a few of the ‘drops’ not working at the deepest depths and redoing them.

cool! something to think about I guess!
My thinking is;
Cheap quality cat6 would degrade pretty fast in salty conditions and especially have signal lose over shorter distances than the more expensive cable. 
60 Mins had a good story on the GoPro founder last night!
Hmm if only it was a story on the founder….
Was much too much like an advertorial for my liking.
Meh it was a feel good story and I though the dude seem like a top bloke! Good on him I say!
