I'm seething, Dom. Nice pictures of livin' large! The coolest thing I've added for the GoPro is the app for my phone. It connects the phone and camera via wifi and let's you see what the camera sees and control it from your phone. Look into it. You'll love it!
Controlling the GoPro from my iPhone Works pretty well out to about 100 yards or so. Never tried it under water. The wifi does drain the battery faster. I added a 200 mah external battery to keep it going longer. It gets a little complicated sometimes. Rg
There's a time lag due to the wifi I'm not crazy about though.
The time lag is there, but at least you can see where the camera is aimed, see what you've recorded, and delete crap footage before you get home. It's also much easier to hit the record button on the phone than to fumble around trying to hit the right button on your head, chest, or a mount behind you.
