Readers who’ve already seen these will have to forgive my enthusiasm for finder this clever combination of shaving and inspection mirrors. My own inspection mirror hasn’t left the drawer in ages, largely thanks to my idiotic selection of a small one just 1.5″ across. The thought was that it would be easier to get into tight spaces, which it is, but once it’s there, it’s like diagnosing through a pinhole. A magnifying version would provide the best of both worlds – a compact mirror with a wide field of view.
Craftsman has a version for just under $13 which telescopes from 12″ to a pretty ridiculous 51″. Regardless of where the offending, invisible problem is, that length bloody well better be enough to find it. A zoomed-in view will add increased speed to that annoying right-is-left, up-is-down hunt for the problem, but once you find it, you’ll definitely be able to get a better view.
