The Coil Master 521 tab is a a tool to help create the perfect coil for your rebuildable tank or dripper, The Coil Master 521 tab is an all in one coiling station.powered by an 18650 battery it gives you stable platform to build on with integrated ohm meter – but unlike your old resistance checker it has the power to fire the coil with the press of a button. That means no more having to move your atty from the ohm box to a mod when you want to burn in the coil. Plug in the voltage adapter and you can screw on your mod and see how many volts it’s putting out. You can even fire your new coil from the mod and the 521 Tab will measure the voltage drop for you.
Coil Master have made a real name for themselves by making rebuilding easy, and the 521 Tab takes that another step forward. Plus, if you’re really in a hurry to test that new build it doubles up as a mod.

Excellent piece of kit!!
Pretty good, but could be better.
After being stung by an Amazon seller for what I'm sure is fake Coil Master kit, I decided to find a better solution from a more reputable seller. The Coil Master 521 Tab is half decent. A little bit light and plasticy for my liking, but it serves as a decent build base and is much better (although still a bit light for my liking) once a 18650 battery is fitted. The 521 Tab comes nicely presented, performs well, gives good / accurate ohm readings when measuring coils screwed into the 510 base and serves as a pretty good build platform. Being able to fire the coil after building directly on the base is a great feature. The 521 Tab also comes with some crocodile clips connected to banana plugs so that you can measure coils not currently connected to the 510 connector. Unfortunately the quality of these leads is very poor and they give inaccurate or inconsistent results. Generally I'm happy. It's a shame Coil Mater didn't go all the way on the quality or all components.
