These type of cameras have their place but really its a matter of working out what your looking for in a camera.
I have a Gopro camera and am currently working through their abilities at the moment.
I wanted an additional camera to add a POV aspect to what footage I catch on my cam corder.
I've been setting up my Gopro place on top of my FoxPro mounted up on a tripod for elevation which I have had limited sucess with so far but so great opportunities missed due not picking the right angle of approach.
It's dificult to predict the direction to set it and these cameras have good width to catch footage but badly lack the ability to give a good picture of game at distance.
I think these types of cameras are very limited as a gun cam given their lack of ability to show up game at much past 15 yards.
An animal at any disance past 15 yards is small in the picture frame and difficult to make value out of.
In an attempt to better value out of the Gopro I have decided to seperate the caller and camera with the idea of opening up the angle hoping that distance won't spoil it placing the Gopreo a little behind the call.
THIS CLIP WILL GIVE YOU AN IDEA OF HOW CLOSE GAME NEEDS TO GET TO BECOME THE MAIN CHARACTER
