The CoilMaster V2

Coil Master V2 coil building kit and 521 tab ohms reader.

 

This review is for all the guys and girls that build! The guys from Subohm recently gave me a Coil Master set for my birthday and asked me to write a little bit about what I think of it. 

 

The kit comes wrapped in a protective plastic packet to keep the case from damage. Upon opening it I was pleasantly surprised at the quality, and obvious effort, that has gone into its design and manufacture. Coil Master has a great product here.
Included is a pair of wire cutters, pliers, foldable scissors, ceramic tweezers, a flat blade screwdriver, a Phillips head screwdriver, a small ohms reader, 10ft spoil of 24g kanthal wire, a rubber block containing an Allen key and six different sized posts, with attachments. It also has an empty space filled with foam - which I use to keep 2x18650 batteries in and, finally, the authenticity card which confirms that it’s the real deal.

 

As this kit is for building coils, I only used what was in the kit to make two standard coils. First, I cut a length of wire from the spool. Next, I chose which thickness post to use. (This is the diameter of the inside of the coil). For these coils I chose 2mm wire and pushed it through the small hole on the wrapping post keeping it anchored. The post adapter in this kit has two holes which allows you to wrap parallel coils. I began to wrap, six wraps plus the ‘legs.’ I used my nail to keep the wraps pushed tightly together. To install the coil into the RDA, I used the same post I had wrapped the coil with to keep it straight and level, and inserted the legs of the coil into pegs. It was the same thing for the other side. I tightened the screws with the Phillips screwdriver.

 

These screwdrivers are particularly easy to use because they have a movable part at the top so you can put pressure on it and twist it at the same time.

To find out the ohms of my coils, I twisted my RDA onto the ohms reader. This takes two AA batteries, has an on/off switch and also a volt meter for your batteries/mod.

 

The initial ohms reading on one coil was 0.51 however, after installing the second coil, it read 0.24. To make sure the coils are tight, and to clear any hotspots, heat needs to be put through them. I unscrewed my RDA from the ohms reader and attached it to my mod. Using the ceramic tweezers I put heat through the coils and squeezed them together. (Using metal tweezers, whilst applying heat, is very dangerous and will cause the coils to short out.)

 

We all know that it’s a bit of a pain moving RDA’s between ohms readers and mods and it looks like Coil Master have come up with a solution! They’ve produced the 521 Tab ohms and volts reader. This box takes a single 18650 which is handier for a vaper than two AA batteries! The ohms reader features an ohm meter, a voltage reader for mods, a coil building deck and the ability to burn coils. It essentially works as a mod. You can attach your RDA/atomiser and use the reader to put power through it. It has non slip pads on the bottom, which is great when you’re exerting pressure through coils. There is a switch on the side which changes the meter between ohms and volts. There is a blue light that indicates when it’s fire mode so no accidental firing!

 

After putting heat through my coils and making sure I was happy with them, it was time to wick it! Coil Master has made this particularly easy with the tweezers and cotton, which come individually wrapped in little packs of five. Using a small amount of the cotton, I shaped it and pulled it through with the pointed tweezers. The foldable scissors are perfect for cutting off any excess cotton - although I often use wire cutters! And the tweezers are perfect for fluffing up and tucking in the ends of the cotton.

 

The ohms reader comes with an authenticity card, a USB cable for charging the battery, two wires with crocodile clips and an adaptor for reading the volts through your mod. The presentation case and the rest of the packaging is well designed and sturdy giving an overall feel that the device is quality and made with care.


Keep up the good work Coil Master, your products are awesome! This is truly a nice addition to my collection.
