If it were me, I would buy used and save money if you don’t like it. I know many people like them, but I did not. I say that for this particular camera but also for the cameras in general. I loved the GoPro, but it was a lot of money just to film for me.
On the Tactacam, I could not find a placement that would allow me to focus the scope to my eye and to the camera. If I wanted to see clearly what I was shooting , the camera would be out of focus and vice versa.
I tried a GoPro and had a similar issue until I upgraded the lens to the Eagle Vision and could then adjust it to the correct distance and focus for the reticle. I also needed an additional spacer for eye replied printed to allow eye placement and camera placement to be in the correct spot for both to be focused.
I don’t know if some people just have perfect vision that matches up to some of these cameras or what, but many people don’t talk about some of those difficulties. Others have said the same as me.
