This was inspired by the one-hitter thread, and more details can be found there. The whole rig. Vaporesso's Transformer RDA atop Athena's Pride 75 mod with a heady glass top for monitoring hit progress. Under the hood. A level 3 inception coil, mounted vertically. It's a coil within a coil within a coil, all on one wire. For each "level", the wire is bent back and wrapped over the previous level. (Not as difficult as it looks, and what else is one to do between hits?) These can also be mounted horizontally. As you can see, the coil heats from the inside out. The outer level is much cooler than the inner - like the passage of time in dreams. It's easy to load, just smear concentrate on top and gently pulse at low wattage. The wire is food grade, low carbon stainless steel. One wire is wrapped around four parallel inner wires to provide plenty of surface area for the concentrate to soak into. Then crank 'er up and let 'er rip! It's a concentrated, deceptively small hit that breaks through stubborn tolerance issues, leaving nothing behind. Who wants to try? A simpler version uses a vortex coil wrapped with the same wire around a conical dab tool tip. With temperature control, this produces more flavorful, less concentrated hits. Just fill it like an ice cream cone!
