521 Tab by Coil Master

Say hi to the 521 Tab by Coil Master - Ohms meter, table mod, and more! For any serious vaper, testing your build and mod is essential for the perfect vape. The 521 Tab by Coil Master has all that you need to test your vape in one device. First, it has an ohms meter that can measure your resistance from as low as 0.01 Ω up to 9.99 Ω. With the included mini alligator clips, measure the resistance of your wire or coil itself without the atomizer. Then when you have the right resistance, flip the switch to "burn" and fire up your build directly on the 521 Tab. Pulse burn your coils and pinch it to your liking or vape on it as an unregulated table mod. The 521 Tab by Coil Master also serves as a voltage meter with the included adapter; Connect your mod to the 521 Tab and accurately measure your voltage drop. 

The 521 Tab by Coil Master can be powered via micro USB* but only requires one (1) 18650 high drain battery (sold separately) to be used on the go. If you're ready to build like pro, this is essential to your vape arsenal. Like the box says, "Coil up, to be master!"
