Currently have three action cameras, which seems a bit excessive. So, I’m selling the oldest of the three, a GoPro Hero5 Black that’s served me well and still works great. Includes the mounting case, chest harness, 64GB memory card, and battery. Extra battery available if interested. It’s listed in Kijiji with the price inflated to account for typical Kijiji low-balling and counter-offering, happy to sell for less to my ECMTB family. Have a look, make an offer.
