Coil Master 521 Tab

The Coil Master 521 Tab is a professional-grade coil-building workstation built for precision and safety. Designed for experienced rebuilders, this device allows you to measure resistance, fire coils for dry burning, and test voltage output, all in one sturdy platform.

With its spring-loaded 510 connector, the 521 Tab supports most atomizers and provides secure mounting during builds. Its bright OLED screen displays real-time resistance or voltage readings with high accuracy. Powered by a single 18650 battery, it includes multiple modes: resistance measuring, voltage output testing, and coil-burning mode.

Compact yet powerful, the 521 Tab is the ideal tool for anyone who regularly builds and tests their own coils.
