Since its introduction at ECC 2015 in Pomona, the CoilMaster 521 Tab has gained loads of popularity, and that's because it ultimately reinvented the ohm meter. This high tech multi-functional device not only acts as an ohm meter, but it also allows you to check voltage drop, test fire coils, and it also acts as a rebuild deck. The process of rebuilding your atomizers has become even easier, and it's all made possible by the Coil Master 521 Tab. Enjoy the equipped 510 spring-loaded connection, a voltage checker, terminal connectors, 2-way rocker switch, OLED screen, and more!
