Coil Master has become a leader within the industry when it comes to accessories for rebuildable atomizers. They’ve developed some of the world’s most popular products that have been highly recognized on different events. The success the brand has built up started from the original coil master coiler, then quickly blossomed as more products were introduced. Its latest and most innovative product is the Coil Master 521 Tab, which is a highly advanced ohm meter that features outstanding build quality, accuracy level, along with the ability to both test and fire coils all on one device. In reality, the 521 Tab is easily one of the most beneficial and essential tools for those who enjoy building.

The 521 Tab features a high grade stainless steel 510 connector at the top, which is accompanied by a spring-loaded brass pin. With this, the 521 Tab incredible durability and contact, which can be compared to some of the most popular devices on the market. This product will ultimately offer the best product for accurately measuring atomizer resistance. When it comes to the 521 Tab by Coil Master, you have to understand the precision that comes with the brand. When using such a product, you’ll receive precise ratings, since the 521 Tab offers readings as low as 0.01 ohms from 9.99 ohms, which delivers feedback and accuracy better than any other device available on the market. The 521 is a very versatile device, which you’ll begin to next right from the jump. It allows users to read the output voltage of most mechanical mods accurately from its included separate voltage adapter.

What’s even more fascinating about the 521 Tab from Coil Master is that instead of using a common AA battery, the 521 Tab actually uses a single, high amp 18650 battery, which has the capability to be taken out and charged externally or charged internally directly from the device. With this feature, you’ll have the ability to use your own selection of already purchased 18650 batteries, and receive the same great battery life in your 521 Tab. Additionally, accessing the battery compartment is quite easy since it rests up under the device and closed off by a magnetic panel. If that isn’t enough for you, you’ll be pleased to know that the 521 Tab also has a three way selector switch, which will allow you to switch the 521 Tab off, place it in a meter position for accurate readouts, or switch it to the firing position, which will actually fire atomizers as low as 0.2 ohms. If you’ve been bummed with screwing and unscrewing during your builds, this will allow you to keep your atomizer solely on the 521 Tab and receive live feedback on resistance levels without having to deal with the screwing and unscrewing process between testing your builds. This product is just as beneficial as the many others that Coil Master has developed, but the 521 Tab offers a level of efficiency that places it in the leading position when it comes to metering devices for our atomizers and vaporizers.

Note: We recommend that you do not fire an atomizer with a short or inset 510 connection, shorted systems, or use an 18650 battery that has less than 20A of output. By not following this recommendation, you open yourself to potential physical damage and harm. If you’re unsure if this applies, we ask that you do not assemble or fire. Furthermore, to ensure the best accuracy from the 521 Tab, use a battery with an appropriate charge.

Coil master 521 tab

Awesome product, first benefit will be less wear on threads, but being able to build, check and test fire all on one device was way overdue. A great edition to any builders tool kit. 12/22/2015
