The title says it all:
How often do you inspect your equipment?
It doesn’t matter the context. If you have equipment you rely upon, it should get some sort of periodic inspection.
When was the last time you checked the air pressure in the tires of your car? Or the oil? Or the washer fluid? How about if all of the exterior lights (turn signals, brakes, backup lights, etc.) work?
How about the fire extinguisher in your kitchen? The smoke detectors in the house?
The backup system for your computer (e.g. Mac OS X’s Time Machine). When was the last backup run? Is everything in order?
The list can go on.
I’m far from perfect in this. I’m like you: busy, with a lot of things on my plate and in my head. I can’t remember everything, and things do slip through the cracks. For example, I wear a kydex pouch on my belt to carry my flashlight and a spare magazine. A few weeks ago I realized that one of the belt clips had started to crack. I’m glad I caught it because it wasn’t too long before it fully broke. I was able to get a replacement ordered in time.
Funny thing tho? The replacement wasn’t properly made so I had to send it back (they did correct things; a topic for another time). Thus I was without the pouch for a little while. I used my rotary tool to cut off the broken parts and whittled it down to just a flashlight pouch. But what to do about carrying a spare magazine? While I do have other mag pouches, it would have made EDC cumbersome. So, a DeSantis Mag-Packer to the rescue. It was good to have some sort of equipment redundancy.
Friend of mine had a similar issue with the flashlight in his car’s glove compartment. The bulb fried somehow, and SureFire is going to take care of it. But better that he found out now instead of when he was stranded roadside at night needing to change his tire.
Any equipment and things you rely upon, inspect them. Fix them. Replace them. Do whatever is needed, so when you have to call on your equipment, it’ll be there.
