This is going to be a bit embarrassing, but my second cam is a GoPro Hero... not 2,3,4,5,6,7... Just the OG GoPro. I do this because, I had GoPros up till the 4 I think and I had problems with all of them except the OG. So, I got rid of all of them except this one and she is a workhorse. As a second cam, I can't fathom spending a lot of money on one. See how cheap I am, I only gave you my $.02
