LT-2000 HEADSPEC (aka Velleman VTMG6)
This fantastic tool is a boon to any Locksmith who does key impressioning, and is just as useful for other close work such as rekeying and repair. Jewelers have used tools like this for decades.
Two bright headlamps provide ample illumination and the built-in magnification is adjustable through 4 ranges. Comfortable, effective and very cool.
