If you are going to stick it on your boom or mast and film you sailing, I don't think there is anything extra to be had after about 3+or 4.
HD and 60fps plenty, don't see the need for wireless on/off etc.
I dunno, I am pretty basic with it.

Image stabilisation is worth considering. GP 5 and 6 have it (and it's very good). I don't think GP 4 has.

4 doesn't have it. Session 5 is also an option with stabilisation & 4K. Sessions are now being run out so good deals around if you want to look for the smaller sized Camera.
check gumtree for deals too

I find the hero 6 great although I haven't used anywhere near it's potential. Image stabilisation is great and even at 1440 res ( I can't play 2 or 4k) you can still crop in and get good quality.

Hero5 session, unreliable but darn amazing picture, light, good battery life, 4:3, true wide angle, now inexpensive.
From my extensive research nothing compares. Wish they'd sponsor me!

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

Unreliable? What issues? are they same with all of the Sessions?

Are the other Sessions better? More reliable?
