This smart looking liner has been crafted from the same great heat treated C-1018 steel as the other Pulse machines. This one piece machined frame along with quality copper components creates it’s distinctive dependability. From a three to a thirteen, the Watson provides the flexibility to dial it in to your lining needs. Loaded with hand wound, hand made Pulse 10 wrap coils for a nice strong magnet. The simple and effective guillotine vise locks your tube down strong. A liner that runs consistently is what produces great line work, and the Watson delivers! It’s elementary.
