Oh I beg to differ here. I've been using mechs and sub-ohm RBA's for a year now, and I don't have a multimeter, instead I've always used one of those little boxes you don't seem to like, and it's worked just dandy for me, and yes it does display my battery levels. I've had no problems at all. Switch or mod malfunctions? I've not seen anything of the sort yet that would require a multimeter, crunchy buttons can't be helped with that, and my mechs have always just plain worked, which is the whole point of a mech in the first place.
venturing into mechs and sub ohm, am I prepared??

In my own experience the quality of the vape becomes obviously poor long before 3.2 volts, and when I notice it dropping off I just screw my mech onto that little black plastic box you advised against and push the button to see where the volts are at. Generally it reads something like 3.72, or 3.68... around there, and I just swap out the battery.
I would get a DNA 30 device which will give you an ohm meter and focus you're research on safe batteries. Once you have the batteries you can read ohms via the device and the DNA 30 will come with a few key fail safe protections built in. You'll also be able to sub ohm on the device. You should still get a multimeter but you can pick that up anywhere including Radio Shack if you have one nearby, whatever you do don't cheap out on the batteries though, get some Sony VTC batteries (VTC3, VTC4, VTC5) and you should be all set.
I think you will find that some of the guys will insist on a multimeter because they like to make vaping as technically sophisticated and complex as they can in order to enhance their own public expertise and the appearance thereof. I've never had a multimeter and don't intend to either. This little $20 box is all I've needed to check ohms and battery levels, and for shorts in the year I've been sub-ohm vaping and it works just dandy. The center connection is for battery levels, just invert your mech screw it on there and push the button. The right side connection is for your atty, and shows the ohms.
Guys will also tell you about all sorts of arcane things that can go wrong using all sorts of technical jargon to confuse and frighten you if you are a girl venturing into what they consider to be male vaping territory, that being sub-ohm vaping, RBA's, and mechs. I've seen a LOT of this, both online and in the B&M's. Makes them feel like they are in charge of your vaping and you.
It does indeed have a 510 on both. Been using it for quite a while now, I guess you just have to order from the right place.
Hm I tend to agree with you here, I am by no means a complete noob, just unaware of anything and just slapping random batteries together into unknown mods and making crazy sub ohm coils and thinking that its okay. I have done my research and I was mainly looking for some advice and confirmation to my setup. I don't know everything, which is why I come here to ask questions and I understand a lot of people really like thinking that they know it ALL and that their opinion is always right and if you don't do it their way, then you will surely fail and blow your head off. That is what I am getting from some people here. I know certain products and methods are better and provide more safety, but to say you ABSOLUTELY must have product X or do method X to achieve certain results is a little annoying at times. I know a lot of people who work with the bare minimum and have never had any issues. They are probably less worried than I am, or at least more comfortable than I am. But less knowledgeable? That isn't always the case.
My friend who recently got into vaping did a lot of research before he bought his first mods, but all he has now is a MVP 2 which he uses to test the resistance of his coils and as a back up, and a K100 and a standard battery charger. He makes a coil, checks the resistance, pops it in his mech and thats all. And here I am trying to buy the "good" batteries, the "good" charger and make extra extra sure I am being safe and I feel like I am on track but to have some people be like "well you need to do this this and that otherwise you are a noob and shouldn't even be around electronics." I mean, it just kinda comes off that way sometimes and its sorta annoying.
But moving on... I have already stated several times in this thread I will be buying Sony VTC5 batteries and the XTAR VP1 charger and I have 3 PVs that are capable of reading resistance. I'm not sure what else I can do to be extra extra safe besides being overly .... about every little detail and making this an annoying, paranoid experience.
On a PT2 I can understand 9W, but a Kayfun?
Coil it to about 1.4Ω, start at 13W and move up from there. WHen it starts to get hot, dial it back a bit. Let that Kayfun roll!
I've seen this from younger guys (<25) in one of the local vape shops. It's pretty rampant. Older guys seem to help women just as if were a man. My favorite local B&M has both men and women who work there, and none of those women would put up with that BS.
But you're right.
It also doesn't help that women seem so much less sure that they can do it just fine. They act timid about it, and get treated like small children because of it.
The only things you MUST have with a mech is good batteries, a way to test your coils, and a smidge of knowledge of Ω's law. Just about everything else is negotiable.
And in some advanced building cases, a good ohm reader in box form is better than a multimeter. Ive found multimeters to be innacurrate on parallel coild builds.
I'm thinking your conclusion is wrong; maybe your ohm reader is just more accurate at subohm than most multimeters, but the multimeter itself doesn't care whether the coil is single or dual coil.
My own little cheap multimeter reads to a precision of 0.1 ohm and the inaccuracy at the moment is about 1.4 ohm (it is reading 1.4 ohm when I hold the probes together).
The 510/eGo ohm readers on the other hand are built specifically for ecig atomizers which typically run from 1 to 5 ohms, so they're going to be more accurate at low ohms than a cheap multimeter.
Hey thanks for this post...I opened it and was 20 seconds into watching it, trying to figure out why you put it up, and one of the people I work with walked in and started talking to me and I nearly became an office chair pooper! haha scared the c*** out of me. So in other words I am blaming my inability to focus at work on you!
What's a good box style ohm reader? I think I would prefer those for the base to build on. Is my Evic and MVP not good enough for reading coils? They are fine for now I guess but will they be able to read sub ohm coils even if they can't fire it?

Oh idk what your local term for what I was talking about is, when I said parallel coil i meant two wires wrapped together to make one coil.
I think you are going to be fine on safety. Now if you want to blow a bit of cash on making that frustrating coil building easier, you could grab one of these

Oh, parallel wrapps; that makes it more interesting; maybe the multimeters are showing a more fluctuating resistance than the ohmreader due to contact between wires.

I've seen one of those coil jigs before and wanted one but... $40 for a metal block with a screw and nail coming out of it??
I think I'll wait for clones or a $10 version to come out. That seems like a more reasonable price. Or maybe I can ask my boyfriend to make me one.So basically when it comes down to it, as far as safety goes, all I gotta do is make sure my battery is properly charged and to change it when I notice a voltage drop and make sure it doesn't get over charged or discharged, make sure my coils have no shorts and know their resistance, and make sure the amp I'm pulling is within the safety limits of my battery, and of course, use common sense.
I can definitely see women being more timid about trying their hand at mechanical mods or sub-ohm/rebuilding, but it's only because media and the ignorant or people who aren't educated about vaping only remember the horror stories of exploding batteries and the dangers and risks. I personally never intended to get into mechs or rebuilding in fear of that, but over the years I have gotten more comfortable by educating myself. After watching a few reviews, reading about the ohms law and looking at battery charts, I can say I feel way more comfortable. Also, I splurged on some good equipment so hopefully I am good to go and don't mess anything up! All I gotta do now is wait for my stuffs from eBay, and perhaps invest in a decent ohms reader. But I think my MVP, Evic, and iTaste VV3 should suffice for now, I don't intend to dip into sub-ohm immediately.
A good multimeter is precise to +- 0.1 ohm no 20 dollar box will ever be that precise. That said a good (emphasis on good, lots of junk out there) will get you in the neighborhood of +- 0.3 - 0.5 ohms. That itself would be ok for normal build and some light sub ohm builds. I don't know if I'd trust it for extreme sub ohm'ing (0.1 - 0.2 builds) but it should be good enough for just about everything else.
Key component when using mechs and building your own coils is having good batteries, if you skimp on batteries you're playing Russian Roulette... with you face!
