so i just bought my first mech got it in today spent the last few weeks learning EVERYTHING or about almost everything... lol but i bought pre built and pre wrapped coils just to keep my shit simple for now. it gives the ohms on them but when i fired them up on my paranormal it gave 0.26 for a dual when one supposed to be .32, shouldnt it be .16 for duel?? i spaced them out a bit do spaced coils higher the resistance? i would think not cause there still the same length of wire! anyways can some one tell me whats up? please and thanks you. btw i just got a vindicator and its my first mech! i think im gonna start using them there so awesome! i love it! even over both my dna250c welll.... for now anyways. i seem to always be loving the next thing i get more ;P

What does each coil measure independently?

Mechs are great. Now the hunt for your perfect build begins. Which atomizer are you using? What brand ant style of coils? How are you measuring the resistance?

.36 would be 0.18 for dual.
Is the coil material ss?
Are all your post screws tight?

Is that what they really measure each or just what the manufacturer says?

It is important to check each yourself, and make sure they are pretty damn close if not perfectly matched in what they read
@VapingReaper27 Manufacturer specs on mass produced coils can often be a bit off depending on who makes them. Doesn't mean they are bad. Which brand and style of coils are you using?

If each coil, measured, indpendently, is really 0.36 ohms, then, yes: The two coils together should come out to ±0.18 ohms. So the next question is: When the result came out to 0.26 ohms, was that with everything assembled? Is it possible one part of one coil was touching a part of the RDA/RTA where it should not? Try putting the coils on the deck and measuring before assembling any further.

thats what the manufacture states
That's not what we mean by "measured."
  1. Put one coil on the deck.
  2. Put the deck, alone, on the mod.
  3. Make sure the power's turned way down. (No more than 30W or so.)
  4. Hit the fire button and see what the mod says the actual resistance is.
N.B.: It may be necessary to fire the mod with nothing attached to get it to "reset" its idea of what the coil resistance is every time you make a coil change.

Remove that coil and do steps 2-4 again for the other. If they match: Install both coils and do steps 2-4 again.

Once you have coils that match w/in a tenth of an ohm or so: Wick your build, prime it, assemble your RDA/RTA and check the resistance again. If it changed from when you had the two coils, alone, on the deck then you've got a short between a coil and some part of the RDA/RTA. Usually means a coil is too high from the bottom or too far out from the center.

yeah i know how to measure it. i didnt measure one at a time though i just threw my own coils on and a dual is coming out at .13 which ima stay at for now! its a much warmer vape and i love it! i was trying to go this low with the pre wrapped coils i bought anyways! but i do get what you mean my last pair wasnt touching the outside of the deck or anything but i pushed it a bit up and looked like it was kinda touch the outer side of the post is that okay? like above the wire hole

Easy there. :)

A friendly suggestion of a little rule of thumb I find extremely helpful here. Love people, use things and do not ever confuse these two. No point loving things, they don't love back even if you think you might program them to do that. I might strongly like the Coppervape mod I use. I don't love it.

I love my wife. I love my dog, critters are not things. Try not to listen to people who say critters are dumb, or smile and agree with them. Add into the conversation, "yeah, humans still fight wars. How dumb is that?" If they go to get upset, "you do realize humans are animals too?" Which we in fact are animals the same as whales, squirrels, pigs, cows, sheep, fish, apes and on, and on.

Apologies if my advice may seem unwarranted, or bearing no merit. Some of us that remember dinosaurs get all musty eyed, and forget a new generation will have its own course of mistakes. We remember some old guy like @The Cromwell yelling at us, "hey you kids get off my lawn!" This leads us to think that since we are turning into that same old guy, we need to holler at kids on our lawns. Truth of it all? Kids will be kids, soon enough they'll learn being adult. Sometimes it's good some adult yells at them to color in the lines. Other times, just overlook the yelling adults. :)

I like 0.30 to 0.50 Ω single coil builds. Find this a "reasonable" balance for maintaining battery life, having some modestly decent vapor & flavor. Have tried dual coils off and on. Nah, not for me when I can do as good, or better single coiled. Have tried 0.20, or lower Ω as well. It gets too physically hot for me to vape and I'm no wimp, well, maybe sometimes. Well, excuse me.

Think I need to, ...

I looked up those coils and they look a bit high mass for a mech and .36 ohms.

Tiger - .36 ohms per coil - (32GA*20GA)+26GA

Agreed, that does read as being a lot of mass for a mech to push.

From CCI Prebuilt coils:

Does look to be massive from the picture as well. You could probably do good using something staggered or parallel. More mass creates more battery drain, and adds to "ramp up" time, even using NiChrome 80.

Might try some 26 awg 316L Stainless wrapped with 36 awg Kanthal A1 for a plain Clapton. Then, add another strand of the Stainless, same gauge as the core, parallel. I've done builds like this and they do really well. May even be able to use (2*26 awg SS316L + 36 awg Kanthal A1) 26 awg SS316L Parallel. Use a "fused" Clapton as your "heavy" and the plain 26 awg as your "light". Either is still not any more massive, or likely near as massive as the Tiger coil.

It is called staggering, though not staggering in the sense of staggered Clapton/s. That deals with how you wrap the Clapton with two different gauges of wire iirc.

All else aside, two strands of 26 awg Stainless parallel does lovely too. :)
