Shotkam gen 4 vs gen3

[paul b]

Im going to doing some instructing and being in a chair cant see over the gun obviously so was thinking of using the shotkam to better evaluate the move on top of the stuff i can see.The gen 4 says it has a faster wifi so would the 4 be much quicker at showing the last shot? 

Is the zoome much better on the 4?

As well as offering 4K video, the Gen 4 has x2 to x8 zoom - that's significantly more versatile than the x4 of the Gen 3 ... BUT it's not cheap at almost £650.

I bit the bullet and bought the Gen 4. My only gripe is that the memory card is not changeable, but I REALLY like the Shotkam. It's helped me a lot with getting my eye back in after a long break.
