Ohm-reader or Box Mod-reader?

Starting out, you can get by without an ohm meter and use readings from your mods. And do use the Steam Engine coil calculator for base-lining your build parameters. Once you get into building regularly, a reader simplifies the process.
For people just get on ohm matters, I think built-in reader is enough, my friends said it will be less accurate than standalone ohm meters, they also suggest Coil Master's devices for advanced purposes.
Some real cheap Ohm-meters can cause problems with the 510-connector, thus reading wrong values. But you can get pretty accurate ones for well under $10. Some mods on the other hand can be inaccurate also.
If you only use mods to read resistance, maybe try your new coils on two mods, if their values are close, you can skip the extra check on the second mod, once you feel comfortable building your coil.

I recommend a stand alone meter. They're usually more accurate and read to an additional decimal place. They also serve as a handy building stand. There are cheap ones in eBay for $10-15, and after I broke about 3 of them I bought a good one from USAOhmmeters.

So I'm getting into building coils for a SMOK TFV4 RBA, should I get an ohm-reader or will the readings from my Sigelei Mini, Sigelei 150w, and my eLeaf 50w be accurate enough?
People who use unregulated mods should use an ohm reader.
When you are doing new coils, if you use an ohm meter then you can be sure you are not powering the coil to measure the ohms. So you may not really need it but it is safer.
I don't have an ohm meter myself, but I don't do low own coils, and my mods check ohms without powering the coil. Plus I have multimeters.
I just use two of...whatever. If the tests don't match closely, I get another mod.

Hey there!
Like others, I started with my mod's reader, but I also wasn't building terribly low resistance coils. The margin for error was acceptable to *ME*.
Now that I'm starting to build lower, I would prefer a better reader. I notice that my resistance readings do vary across my mods, so I can't *just* go by one particular mod.
If you're getting on a hairy edge, just build a little higher to be safe....
Re: Steam-Engine and such, I always forget to take into account my leg-length when trying to figure out what my build should be. You probably should measure the legs (or measure one and double it) to include as part of the build. Makes Steam-Engine happier
Well the iStick 50W is known to read ~.15 ohms over the actual resistance, so already that's a no.
But these days, the stand-alone ohm readers are generally as accurate/slightly more accurate than mods. I'm comfortable using my mod for resistances, but a year or two ago I wouldn't have tried building without one.

I've been through many devices and tested many as well... I have found that most devices with built in readers are just as accurate as an ohm reader you'd pick up from a vape shop/online store, for the most part. Most ohm readers designed for 510 threaded attys usually give an extra decimal point, but that is about it.
They are accurate enough, but just note that the lower you go... the more inaccurate it will become. Don't let this bother you too much but just be aware of it, especially when getting to lower extremes of sub-ohm. If you are worried about it being 0.1 Ohm or lower off and being dangerous, then I wouldn't trust the readout.
If you want a true ohm reading, then get a professional multimeter... though the good ones start around $300 USD, so it isn't too practical to get one just for vaping.

I always thought it was safer to check my coils on a meter before I put them on a mod. When I started building, I didn't have a mod with a display, so meter was the only way.
OHM meter for diagnosing, building and servicing. Mods meter for reference and warning ONLY. Never know if whatever problem you are working is partly due to a malfunction of the mods meter or logic. If reading don't match, I trust neither. In this case I use an average of the reading given. Unless I know via testing which is the more accurate meter reading.
This is the one I like, the "Ultimate" model, floating 510 pin, $27 + ship:usa ohm meter stainless steel 510 floating pinLink please!
They also make on that holds an 18650 and can fire the coil for testing but it's $100 or so. You'll probably get a better buy on that with a 521 Tab. I can't go bail for the accuracy of the 521 though. The USA parts are seriously accurate.
I have an ohms meter but it is as inaccurate as mods are. I just use my mods. As long as it is on a regulated device it is not going to make a difference being a touch off. As for a build on a mechanical and going super low ohms I would want a good accurate one. When I build coils I know what ohms I am shooting for, so if I get a number that seems out of wack I know something is wrong. CHEERS!
I'm with everyone on the built in meter being good enough for you now. It's always good to double check, so confirm coil resistances with two mods before vaping. A lot of mods coming out now don't even require the coil to be fired to read the resistance, but I haven't owned those 3 mods, so I can't comment on that being a feature in those.
I do however recommend a multimeter. Since you're running regulated mods, the resistance isn't your biggest concern for being safe, but will need to check the voltage of your batteries after discharging and charging. You can find multimeters rather cheap, so I would just put the money you would've spent on an ohmmeter towards a multimeter fund.
edit- here you go...very helpful. I would've gone crazy when I switched to stainless steel 316L wire if this wasn't available to the world.
