You Talked and We Listened
We are constantly upgrading the Smoke Stick to make it the easiest, most hassle free way of detecting air leaks.
Upgrades to the Smoke Pencil ONE include a more robust battery cover with improved configuration, a green LED light to make the smoke more visible, new trigger locking mechanism that makes it less likely to activate the trigger accidentally while it is stored, better visibility on the fill / empty tank windows to read the fluid level, higher quality tighter plugs on fill and empty tank, and new fog fluid with higher glycerin content for thicker vapor with less sputtering.
