The real power of a go pro is its ability to get the shots that you can’t get with a larger camera. If you want cool video look for any angle or crazy place to get video. Get creative.
The one draw back of decoy cams is battery length. You have to put on record and let sit. The WiFi won’t go that far. You shoot 30 min of video for 10 seconds of cool video. Bring extra batteries but that angle can be awesome.
Selfie sticks work great for getting into cool angles or for self filming. A lot of how I use though is just placing it places. Like on road and having truck drive by, under the water to show walking through water etc.
Oh and a gun mount. Although I like the shot of looking back at shooter more than looking at shot at bird.
