Been lurking in here for a while learning what I could about all things laser. I wanted a unit for engraving some firearms and stocks. Not a real job, just playing / hobby stuff. I do refinish firearms (Cerakote) and might do a little custom engraving. Anyway, I found a deal on a factory trade-in (lightly used) unit that was less than a year old that seem like a good deal for my purpose. Unit has same warranty as a new one. Guys and gal at Boss Laser have been very helpful and unit was well packed and arrived undamaged. Now.......... what do I do? Engrave something? Setup won't happen till Friday.
