Coil Master 521 Tab
The Coil Master 521 Tab is a multifunctional device for both beginner and expert rebuilders. This device allows you to screw your atomizer into the 521 Tab's 510 connection and use it as a rebuilding station. While connected, you can check the resistance of your build and also fire the atomizer, allowing you to check for hotspots and dry burn coils. The 521 Tab will also function as a volt meter for both regulated and unregulated mods. Lastly, you can use this device as a table mod by using a long or gooseneck 510 to 510 extension. It is powered by a removeable IMR 18650 battery (not included) which can be removed and charged, or charged internally via micro USB cable.
