Authentic Coil Master 521 Tab

Coil Master 521 Tab (Authentic) – $31.29

Here we have the updated version of the Coil Master 521 Tab. This latest version has a few improvements that make it one of the best choices if you’re in the market for one. It’s powered by a single 18650 battery which I’m sure you have a few of them lying around, so there’s no need to go out and buy different ones to use in this. It can read a resistance all the way down to 0.01 ohms with very good accuracy, and can measure the voltage drop off of your atomizer between the range of 0.3 to 9.99 volts.

The Coil Master 521 Tab has a spring loaded 510 pin so your atomizers sit flush and don’t wobble around while you’re building on it. Plus not only is this an ohm meter, you can actually test fire your builds right on this thing, so you don’t have to swap it over on a mod just to test your coils and get them glowing evenly. If you’re the type of vaper that prefers to build your own coils then this Coil Master 521 Tab is a must have.
