GoPro Hero (1) HD. Comes with everything pictured. Lots and lots of accessories. 1 Battery. Waterpoof case is pretty much new. Pictured with barrel mount and low-profile screws for better FOV (I preferred to mount upside down underneath the barrel). USB plug is a bit iffy (still works, but loses connection when wiggled too hard), so file transfer using a card reader is safer. No SD card.
$80 paypaled and shipped. $5 off with a purchase of a barrel cover.
If you're going to offer a lower price than what I'm asking, please show me a comparable listing that I should beat.
