I own and have used a Tactacam 5.0 (long range for rifle, as opposed to the one designed for short range bow hunting).
I’ve used it on tree stand hunts, but not for still hunting like the one you are planning.
Observations:
- there are 2 ways for mounting it. Directly on the scope facing forward or mounting it facing rearward and filming through a periscope. The 2nd option seemed cool as it records what you see through the scope, including the reticle. BUT you loose a lot of eye relief and light transmission. In my experience it’s great for low recoiling rifles.
- it changes the balance of the rifle.
- you can install it canted to the left side of the scope (for right hand shooting). It will enable you to shoot the rifle with both eyes open as it will block you’re left eye when you mount the rifle and will allow the use of the (dominant) right eye.
- you will lose the recording of the shot during the recoil - obviously.
- it has 3 different settings, so you can customize it for 3 different zoom levels depending on the distance to your target. They are fairly easy to select.
- you can have a remote that will allow you to power it on/off and select the modes while you have the rifle mounted to your shoulder on sticks or a backpack.
- it will be an extra step you need to mange during your hunt.
Good luck.
