Is getting a mech mod worth it?

Cleaning them is the fun part for me lol

I was thinking the same thing...but then I like tearing things apart just to see how it works from the inside out then putting it back together. That's a way to really know your device and with mechs there is t much to them.

I actually do that with most every tool I buy.
I tear it apart and see how its assembled, so I can understand how it works and how to service it.

How do you measure resistances that low, and how do you know you're not at .06 or even .05Ω?

As a point of reference; on a number of my regulated mod's I run firmwares that displays resistance to milliohms (.001Ω)

Example below (all day mech vape resistance checked on one of my reg-mods):

The hardware in the mod isn't accurate, regardless of the firmware.

Ohm readers that are accurate enough to correctly mesure 1/1000th of an Ohm cost much more than that mod.

I never understood the purpose of going so low. My mods will chuck anywhere as far up as .3. I usually stay in the .29-.20 range and the few times I have gone down as low as .15 the only thing really noticeable that changed was having to change batteries more consistently.

If the mod resistance test results are repeatable (reads same from one test to another - just checked that same atty now and measures 0.094) then I consider the results acceptable.

Changed to another mod and get slightly higher reading (0.102) that is also repeatable on that mod. Again totally acceptable in my mind. Run a resistance offset on the mod to calibrate if it matters that much. To me, reg-mods display approximate resistance values. So long as the value is consistent from one test to another that's what matters to me.

I have one mod that reads batteries slightly off from actual and results in battery imbalance issue at about 1/2 capacity. I run BOV (Battery Offset Value) to calibrate the bat-1 & bat-2 readings and all is good.

Every device potentially reads differently unless calibrated to a standard.

Calibrated Multi meter at work and then a ohm reader at home I would. Never trust a home 20$ ohm reader fully on a build like that
All of our stuff is on a 30 day calibration cycle

I wouldn't trust anything to be 100% accurate when measuring that low.

Doesn't mean that it's accurate. Highly doubful, in fact. Any small interference will have a huge impact at very low resistances.

Sure, but with mechs and dangerously low resistances you really need dead-on accuracy.

RE: "Dead on accuracy"

Please describe your tolerance.

For my needs .005 accuracy is acceptable. What is your level of acceptability.

From your numbers, .008 accuracy although as you don't know which mod is correct or if any have 100% efficiency (as stated from veteran posters, something with 100% accuracy would cost more than the entire mod) I don't understand where the "accuracy" part is coming into play? Also you say the .008 may be acceptable to you but that is a difference of 41.17 amps or 44.68 amps on a mech going off the ohms you stated.

There's simply no way your meter is that accurate. You're making an error in thinking that the difference in the reading between the mods is what matters. Either of the readings could easily be off by .01Ω or more.

Ya I'm with ya if it was a all day vape kinda thing or even for a long time and ya it's risky but I like the vape of it.

My norms are .14 in a tube
.1 in parallel .28-.35 series with lg hb6

Your mod isnt accurate to 1/1000 of an ohm but Ill play:

A margin of.005 when vaping at .5 ohms is acceptable.

A margin of .005 when vaping at .009 ohms is unacceptable.
It means your equipment can't accurately measure a dead short.

Different mechanicals have different resistances or Voltage Loss and they can be drastic.

I bought a REO. I had a volt tester and it showed that the Reo was putting out only 3.2 V. . I returned the Reo with a fat restock fee. I proceeded to post in the forum about it and received a mountain of hate from the Reonauts, to the point where my post was stopped and two other posts were deleted. Rob noticed and came out with a new version with lower resistance parts that started at 3.7v. I bought one and was happy with it.

I used to have fun because I'd test the resistance of the Mods and some of the really expensive ones lost a lot of voltage and the cheap ones actually outperformed them.
