Hi all, new guy here. I have had a GoPro for about a year - use it to make fishing videos (which means LOTS of video to catch a little bit of action). I bought the battery backpack - extends the battery life to about 5 1/2 hours and I still haven't filled my 32g card in one outing. but I would rather have too much memory than have lose footage for being out of space (one less thing to worry about).
