Yes I have. I have used it in Field target and Hunter Field target with airgun, and it absolutely did the job of videoing. What I didn't anticipate to be fair and should've realised is how long video takes to edit if it's not your skill set!
It's also a very niche product, and I am going to reconsider whether it is a long-term keeper for me. Through no-fault to the tree you come but through my video editing skill and speed! I wondered if it was more appropriate for the hunting community?
