@BONES for straight up action shots, autonomy and ease of use... Nothing beats the AirDog (since our last weekend up in VA, I've been doing some research ~> all the reviewers have rated this one the best). I love that you can just place it down, wear the arm band, press a button, and it does everything!!
Best performance and small footprint... get the Mavic
Best value/bundle... get the Karma
We picked up the Karma last night ~> @Sideslinger will be piloting from the passenger seat.
