Coil Master has managed to establish itself as an important company in the vaping industry with top of the line accessories. Coil Master’s impact in the vaping world is quite important as they have offered us a better and quicker way to build. This is mainly due to the release of some interesting products, out of which I would like to mention the Coil Master DIY Kit V2, that I have reviewed a while ago. In  today’s review I will also be featuring other accessories from Coil Master however the focus will be on this little tool – The Coil Master 521 Tab.

What is a Coil Master 521 Tab?

The Coil Master 521 Tab is essentially a multi-function tool  that enables you to rebuild coils for your atomizers in a safe and quick way. The fact that it is so versatile it will certainly make it even more appealing to take it away with you, this tool ca replace all of the below in a small and compact package:

  • An ohm reader
  • A voltage meter for mechanical mods/regulated mods
  • A coil rebuilder/testing deck
  • A table Mod

Box contents

Coil Master 521 TabPackaging for this device looks top notch, the device arrived in an eye appealing red and black presentation box with the Coil Master logo embossed on the top of the box and 521 lettering on the sides. All the accessories are nicely tucked in and easily reachable.

 

The box that I have received contained the following:

  • 1 x Coil Master 521 Tab
  • 1 x Snap-on adaptor for voltage readings
  • 1 x micro USB charging cable
  • 2 x alligator test leads
  • 1 x user manual
  • 1 x promotional giveaway leaflet

Look and feel

The first thing that caught my attention was it’s design, it’s a beautiful device with a small form factor. The size of the device is spot on for it’s purpose, it’s not too small to make it difficult to build on or too big to leave it at home. The device is 84.5mm long X 69.5mm wide x 49.5mm in depth. Size wise it is comparable to an ohm meter but slightly bigger. The overall material used is hard plastic (ABS) for the device and the shape is ‘box style’.

On the top of you device you will have your building deck with the integrated 510 connection, which looks recessed into the aluminium top cap, the 510 brass pin is spring loaded and it has made a connection with all the atomizers I have tested. The device also features an LED display on top of the 521 tab, the display is nice an bright and shows the necessary information (ohms/voltage). The previous version of the 521 tab featured an OLED display that also showed a battery meter and had a couple of graphics when you were in firing mode, the version I have on review is the newer model that doesn’t have the OLED display.

Coil Master 521 TabI favor the old OLED display but there is merit in keeping things simple (for instance it saves battery life). Next to the display you will find a big firing button that sits nice and firm and has a pleasant sound to it. On the left part of the display you also have a blue LED to let you know that you are in firing mode. On the right side of the device you have your mode selector (burn/off/reader) and down below you have your micro USB port for charging. Coil Master 521 Tab

The left side of the device has Coil Master 521 embossed that adds to the design and details put into the device. On the bottom side you have the battery compartment that is fixed into place with two tabs to prevent the cover from sliding off and magnets to prevent it from falling and to allow you to easily replace your 18650 battery without tools. The battery cover also has 4 rubber pads to prevent the 521 tab from moving on your table or any surface when you are doing your builds.
