Another item that is staple in my shooting bag is a good pair of binoculars.
While I am certainly not an optics snob who needs a $3,000 pair of binoculars with a built in range finder, I do need something good enough to use at the range to either locate targets, spot hits for other shooters or to record shooting footage for my YouTube videos.
What attracted me to the pair specifically was that they were fairly light weight at 1.25 lbs and used a BAK4 prism and came with a smart phone adapter.
The BAK4 prism is a Chinese variety and slightly trails the German standard, it is far superior to the lower end BAK7 prisms, having a better refractive rate.
The smart phone adapter was well worth the money as I could mount my phone and have it record the target cam footage. You can see it in use in my latest Ruger video on the 300 PRC.
