I have had over the years Go Pro 2 - 3 and 4.The 4 cost almost $500.
These cameras are used to film vintage race cars. I misplaced the 3 so I then ordered the Hero 4. I have to say it is awful in race cars. The sound goes in and out.
A while ago I contacted Go Pro. They told me there had been some software upgrades controlling sound volumes. I asked what's the point of that in a race car. He had no solution.
Hero 2 worked just fine. Also I also notice that the camera cannot record an airplane propeller at the correct speed. Apparently it can't record at a fast enough pace to keep up with the propeller. Not sure why they are so successful out there in the market place.
It's time to look for alternatives!Tony Hart
