Just got the GoPro for this season. It's HD so yea the quality is good.
I did run out of space but the best footage would have been the 3-4 attempts trying to flip it back over in the rapids. Our first time boater fell in as one of our attempts failed and she did fine not panicking and got back on to help get it over. The second flip we ended up floating into the takeout upside down.
We flipped right before a long series of waves and tried towing it to shore but the current and rapids were too much(two rafts towing). So we finally made the decision to just flip then. I took two tries with two of us then piled 4 on it and finally got it over after about a mile and a half
