The Go pro can be mounted but it doesn't have a zoom function. it has a fish eye type lens. I tried it with mine and it is good but to a certain range pag malayo hindi mo na kita up to say 50 ft. kaya.
The problem with just a digicam is its durability with all the shaking crawling and etc. And you will be all conscious about it. It may affect performance.. Anyway I went ahead and purchased the Contour Roam. I have an idea for its zoom which i may need your help in. I shall post na din a review about it once i receive it. I'll post na din a review about ordering from amazon and having it brought here directly as I worry about customs.
i used my GO PRO on my gun. i just mounted it too my AIM point using the bike handle mount.... but unless ur keeping ur gun up at all times u get alot of time looking at the ground as u run around...
