Since the primary focus in your hands is your rifle, it's probably not a good idea to be fumbling about with a one or two-hand device.
Unless one is scouting territory out, in which case, you can split attention between binos, camera, and eyeballs. And, for scouting, photos let you examine a given image is greater detail than you often can give in person.
Now, if you think that you might run across views/images that might be worth sharing, then the answer is probably a head-band or bill-clip GoPro. (Another option is to use a walking stick/monopod mount.)
Now, GoPro occasionally gets a bad rap. And, I get that, compared to a 'serious' video camera it's kind of like a cheap cellphone camera. The output is occasionally hard to edit, and sometimes hard to single-frame screen capture (that gets to technical details on the cam set up that are not germane here).
Now, the latest edition GP have motion/blur correction, and are very miserly about memory storage. The form factors (how big/bulky they are) have really improved.
And, none of this is any guarantee that all your footage is a pretty boring hike through the woods, or the hills and valleys, or just over the lip of the blind seeing nothing. But, if you do see something, you'll be able to find it again. At least in POV (point of view) format if on a headband.
Are there competitors to GP? Yes, but, you almost need to use GP as a learning tool to know whhich of the alternatives are better for you. And, better for you, is a critical distinction.
