I've found the Tactacam makes a good product but it can be difficult to focus to a given scope. Brand may not matter. Therefore changing between scopes may result in different results when it comes to focus, without more finicky adjustments. In some cases I could never get the focus done properly.
The product delivers in my eyes to an extent but falls short. To me, it's not the best option. I like the EagleVision setup with their custom Gopro lens. I've been able to easily focus to at least 5 different scopes without as much difficulty and better success. Perhaps I didn't watch the best video on YouTube to tune my Tactacam setup but since it isn't as intuitive as simply turning the lens on my Gopro 7 aftermarket lens I gave up on the Tactacam for a Gopro plus EagleVision scope cam setup. I spent hours working on this and therefore to me its a second rate product. Queue the negative responses. I'm OK with it.. I don't want to spend hours tuning my camera. Instead I prefer minutes.
With an EagleVision and Gopro setup it's been super easy to switch between an Edgun Dedal Stalker to a Hawke scope to an Aztec scope. Definitely not so easy with the Tactacam.
This is a personal perspective I have. You can refute it, deny it but I'm set on a different platform for my scope camera usage.
I literally change between Aztec, Hawke and Edgun Dedal Stalker without spending much time using my setup. I have a YouTube channel with 2 of those scopes (edgun and Aztec) which I change my setup between them with zero changes and get great results.
