The Coil Master 521 Tab is an elite level ohm meter that is unprecedented in build quality, accuracy level, as well as its ability to test and fire, presenting one of the most dynamic and essential tools for building enthusiasts and beginners.

Featuring a high grade Stainless Steel 510 alongside a spring loaded Brass contact, the 521 Tab offers matching durability and contact as compared to the most popular and renowned devices and box mods today, giving users the greatest parallel in accurately measuring atomizer resistance.

Precision ratings are extremely high, offering readings down to 0.01 ohms from 9.99 ohms, offering a level of feedback and accuracy that places the 521 Tab among the highest level in readouts. Also included is a separate Voltage Adapter, and when properly inserted, allows users to accurately read output voltage of most mechanical mods and devices.

The 521 Tab utilizes a single, high amperage 18650 battery (sold separately) that is capable of being charged directly from the device, offering users superior battery life. A three way selector switch allows users to switch from off, to meter position, to a firing position capable of firing atomizers down to 0.2 ohms, giving users live feedback on resistance levels without having to screw and screw the atomizer between testing. This capability drastically increases usability and efficiency, making the Coil Master 521 Tab currently the most comprehensive and high quality vape specific metering device in the market.
