Binoculars in your range bag
I have a pretty good range bag that I keep all of my sight in tools and magazine conversion kits in it. All of my hearing protection and sometimes a few loaded magazines. The one thing I have always kept in there were my binoculars. I have taught so many people to shoot firearms and there have been times that I totally forgot to bring a rifle with magnification on it when I was teaching new shooters to shoot with a 22LR and iron sights. It’s good to start people out on iron sights whether it’s with a 22 bolt action or an AR15 A2 style rifle. If the shooter is old enough and can handle the nose and the recoil the AR15 is a good starting point.
When you try to see those groups at 100yds, sure you can hit a once inch square at those distances and accurately group them, but if your sights are off or you are trying to determine where your novice shooter is hitting, you don’t want to have to call cease fires and check paper. There are many differences in the light gathering abilities of optics but Bushnell binoculars are reasonable priced and for most practical purposes, they get the job done and won’t cost you hundreds of dollars. It’s always a good idea to keep your lense clean and this can have a big impact on your light gathering and clarity.
