What are the C batteries for? Haven’t seen anything in many years that take a C battery.
Smaller flashlight and radio. We use more Cs then Ds in the house so you go with the equipment you have.
Vibrator(s). Hey, when yer prepared yer prepared.
There is a mag lite that is just the right size to carry around the property at night which runs on C. batteries. I also have a very sturdy streamlight LED lite that is incredibly brite and runs on Cs.
Im trying to get away from my surefire and pentagon lights that take CR-123 batteries. The batts are too expensive and dont last long enough. I have one surefire on each of my homeland defense rifles and one on the surefire in my active shooter bag under the bed with a dozen rounds of hornady tap buckshot and five 31 round 9mm glock mags.
