This is especially handy       for reading the microprint that is now common on devices (does       that say "12V @ 0.2A" or "15V @ 0.2A"?). The flash/illuminator       makes this particularly useful in low light situations (like       when you are trying to examine a device at the bottom of a       pallet of other devices and don't want to have to unload the       pallet just to gain access to it!)              [You can, of course, also use it as a "variable gain magnifier"       if you can maintain a sight line to it while viewing the       object in question]              I used to keep a jewelers loupe in the console of the car but       that proved too tedious (trek out to the car to fetch it any       time you needed to see something "fine" -- the phone was in       your pocket as a timepiece so much handier!)              --- SoupGate-DOS v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
