Hi Steve, I'm very impressed with the GoPro Hero 5 Session. Doesn't have a replaceable battery as
@jn1 mentioned, but I figure that at $300 and a high likelihood that I will damage it well before the battery gives up, its an awesome little beast. I cant imagine that the session 6 could be any better for the extra cost

.
I made up a dodgy boom/clew mount with a $2.50 bit of pipe from Bunning which gives really good vision of my feet (and pot belly

) for first day on the new foil board (below). Back foot too far back= trouble
