The Coilmaster is (right after the e-cigarette) the best friend of every self-developer. The winding station offers a stable base with the 510 thread to insert new wire windings into the RBA evaporator. Once this is done, it really starts. Powered by a 18650 battery (not included), the Ohmmeter accurately measures the resistance of the produced winding. The measuring range is from 0.01 to 9.9 ohms. Very practical is also the possibility to put new windings under tension and annealing. So you can comfortably get everything in shape and eliminate hotspots. Always use non-conductive tools or switch off the power. Resistors> 0.1 ohms can be fired.
