I bought one about a month ago. Like so many things, I have to get one, and then don't use it when I receive it!
But today a new shooter friend of ours was over, and after she did so well popping Mini Charm Pops at 25 yards, I figured I would try to set up the Tactacam for her to have a 'souvenir' of her shooting.
This was a real quick-and-dirty cam set-up and video edit (Davinci Resolve). And then lost resolution when uploaded to YouTube. In edit I zoomed in around 2x to remove some of the 'shooting through a tunnel' appearance of the video (and thereby lost some of the original 4k resolution). No color correction was performed, and by the time we took the vid the targets were pretty much in the shade. She didn't have any issues using the scope once the camera was mounted onto it.
I'm sure that the system can do better, this was a quick first use of it by me. I didn't even take the time to focus the ocular lens on the reticle when setting up.
I think it will be a good unit when I get more experience with it. Good flexibility in mounting to various diameter scopes, and generally easy to use. Used WIFI connection to my phone to start/stop the video. It definitely got the job done today, even with zero experience using it.
