The Coil Master DIY Kit and the Coil Master 521 Tab. Must haves for all serious vapers!

I wish there was something like this that came out when I first started vaping! When I started trying my hand at coil building, I had an old nail cutter, a rusty old precision screwdriver, paper scissors and a drill bit set I bought from the dollar store. It wasn’t much but it did the job.

I was offered the Coil Master DIY kit and the 521 Tab to review from Coil Master. As someone who has been vaping for a while, my initial thoughts were, “Eh, I don’t need this stuff.” My hardheadedness was put aside after using these products, and it made my coil building so much easier and enjoyable.

Why did I not get something like this sooner? It would have save me tons of time, wire, cotton, and frustration. No build is too hard to do after using the DIY kit from Coil Master.

Let me swallow my pride and my know-it-all mentality about coil building and give you the reasons why I truly believe every serious vaper (especially the ones who are into doing their own coils) should invest in these products.

I said invest, not buy. This is more than a purchase in my opinion. Everything you need in coil building will be found in this kit! This kit pays off in the long run and is of great value when you consider the pros of this product! Don’t believe me? Keep on reading.

So what do you get with the Coil Master DIY Kit? For under $50, you get some good quality tools that make you an instant professional coilsmith (is there such a word?).

The kit comes with a wire snipper, needle nose pliers, flat head and Philips screwdrivers, ceramic tip tweezers, angled tweezers, retractable scissors, a spool of 24 gauge Kanthal (10 feet, which you can use the spool again for other wires once it runs out.), an ohm reader, and the Coil Master coiling kit. There is also a slot that holds 2 18650 batteries which are not included.

I have been using this kit for more than a month now, and the thing I love about the DIY kit is the tools included are made for coil building. I love using them, from the wire cutter to the scissors. All of them do the job and they do it well. The angled tip tweezers are a life saver, really helps me get into those hard to reach places.

The Coiling kit makes wrapping easy. The lower the number, the thinner the gauge. It’s pretty simple to figure out and use. I watched a couple of YouTube tutorials before I started using and hey, it worked out great for me. I love how it gets my wraps perfect every time I use it.

A lot of reviewers say this kit is for intermediate or advanced users, I disagree. Coil building isn’t all that hard if you have basic craftsman skills. The DIY kit makes it so much easier because the tools in here are all you need for making your own coils. Like I said earlier, I wish I had gotten this kit earlier, now I can’t stop using it.

The Coil Master 521 Tab: Ohm Checker, Voltage Checker, Coil Tester and Building Deck All In One!

Before I had the Coil Master Tab 521, I would use my old, unused mods as a deck for building. Although it was useful, I read somewhere that doing this would mess up the connection on your mods.

If you are going to be serious about coil building, it is necessary to have a deck you can build on, read your resistance and test fire your builds. The Tab gives you all these options, without having to constantly unscrew your RDA’s or tanks.

The 521 Tab looks beautiful, and is very efficient. Having a dedicated deck to coil building reduces damage in comparison to using your vape units as a deck like I mentioned earlier. Sure, there are other decks on the market you can buy, but they are either stand alone decks or they don’t have the capabilities as the Tab 521.

What I love about the Tab 521 is right after you are done doing your coils, you can go ahead and test it. This saves time and deals with faulty coils by nipping it in the bud. You don’t know how frustrating it is to spend time wrapping coils and making sure they are straightened out, only to find out that they don’t work.

The Tab 521 comes with 3 different options. Switch it off if to do your coils, put it on meter to see what the resistance on your coil is, and switch it to burn to test fire. Yeah, burn baby burn!

It is powered by 1 18650 battery. It also works with a micro USB chord, but it won’t be able to fire and will only be able to read the resistance on builds. So basically, you can use this Tab 521 as a mechanical mod.

Thank you once again to Coil Master for these wonderful products, and like I said earlier, these are good investments for serious vapers. I still use them and will keep using them unless Coil Master comes out with something better, but these tool are basically all I need for building my coils.

And for the price it is at, it surely is good value for the quality and usefulness it brings to anyone who chooses this to aid their coil building. It makes things so much easier especially for those who build on a regular basis.


A Chemist’s Advice: “Don’t Dry-Burn Your Coil.”


I came across this article on Facebook about a chemist’s advice to vapers to not dry-burn your coils.

Dry burning serves 2 purposes: test out a newly built coil and to clean it.

Some vapers advise to dry burn usually under 30 watts but Dr. Mirosław Dworniczak, a smoker turned vaper, advises otherwise.

Dry burning causes the oxidized coating on coils to peel off, which become microscopic particles. These particles are small enough to travel through the vapor making their way to your lungs.

These particles can cause allergies and in a worse case scenario become toxic.

Even though dry-burning causes more harm, the harm is still a very small threat compared to cigarette smoking.

 What To Do Instead of Dry-Burning

The advice given in the story is to use non-contact coils, or spaced coils. It avoids heat spots and is easier to clean.

You can also use the newer ceramic heads that are gaining popularity, these are much safer to dry-burn compared to coils.


Ceramic Heads Vs. Coil Heads: Which Is Better?

I have been vaping for a while now, witnessing how vaping technology has progressed in such a short time. I still laugh when I think back to 3 years ago when I used to vape on my tiny 350 mAh e-Go mod, trying to blow big clouds on that little thing! Those were the days!

I’ve seen vaping progress from mechanical tube mods to touchscreen box mods. My first variable wattage mod went from 7 – 15 watts. Now they have mods that go all the way up to 200!

So here’s another vaping innovation that I’ve noticed is picking up some steam. Ceramic sub-ohm tanks are starting to gain more demand from the vaping community, and I would like to point you guys to that direction in this post.

What are Ceramic heads?

Instead of your traditional wire, ceramic is used as the heating mechanism with these type of tanks. I’ve watched some videos on Ceramic heads by vape reviewers, and a lot of them are saying some pretty good things about Ceramic.

Lasts longer – The ceramic  heads last about 6 months, probably even longer if you are careful enough.

All you have to do to clean the ceramic head is dry burn it under 30 watts. Also, be careful in cleaning it since knocking the ceramic head out of place will cause it to short.

No more coil building – This appeals to me the most, the thought of not having to wrap coils for at least 6 months on this tank is heaven.

Sorry if I offend any of the coil-building vape purists out there, but that’s just me keeping it a buck.

Cleaner taste – A lot of vapers have noticed a “cleaner” taste when compared to the traditional coil heads.

Harm reduction – The same reviewers also claim that vaping on ceramic has less toxins than what you would find on the traditional coils, however the amount of toxins on coils is minuscule.


Now for the cons, of course you didn’t think Ceramic heads didn’t have any flaws now, did you?

Longer ramp up time – Expect a little more time for it to heat up when you press the fire button.

Eats up juice faster – So the clean tasting juice comes with a price, it goes through e-liquid rather quickly compared to using coils.

For me personally, the cons don’t really discourage me from getting a ceramic tank of my own.

I will be doing a follow up post on Ceramic heads, particularly Ceramic sub-ohm tanks once I can get my hands on one. Stay tuned!
