Do APV users need an OHM checker?

Yes, and that's why we have them on 99% of the APV's today. One of the last hold outs was the MVP. It got its ohm meter last month, and now all is right in the VapeWorld. I also use a dedicated Ohm/Cartomizer reader (the ones with the 510 connections), and find them quite easy and convenient to use. These are quite handy, and I find them easier to use than a DMM. YMMV. Good luck!
An ohm meter was one of the features that I wanted when I was looking to replace my spinner battery. I ordered an MVP V2 and am eagerly awaiting it's arrival so I can start checking some of the pt2 heads I have recoiled, but haven't got to use yet! From what I have read, taking ohms reading will not harm the battery because it is only sending enough current to check the resistence. But I am a noob, so that may be hog wash! 
With an APV that has an ohm checker and monitors device resistance you can't hurt it as such. If the device is out of range, open or shorted the APV will display an error message and won't fire. The only issue is these ohm checkers on APV's round to only one position right of the decimal and may not be all that accurate. My Vamo says my current coil is 2.5 ohms. My meter says it's actually 2.36 ohms. I believe the meter.
An eVic isn't so convenient because it doesn't have a button to force a check but I generally wrap RBA's on my Vamo and check as I go. As far as checking the actual head it's better because you don't have to subtract the wires of the meter.
An ohm meter is still handy to have if you wrap coils off the mod and for cutting wire lengths. I can wrap a micro on my needle while connected to the 10' length, check it and add or remove a wrap if wanted, then cut it off.

Personally, I'd recommend having a multimeter. You can use it to check the resistance of coils but also to check the voltage of batteries. Yes, I know the APV does these things, but I think it's a good idea to also do them with a meter.
Evic checks and so does the Mvp2.0 that I have but if your a builder I would suggest a separate meter. Just like with all the tools I have as a motor cycle restorer can't have enough tools in the tool box.
I agree double checking doesn't hurt and there are times when a meter is convenient for other jobs.Personally, I'd recommend having a multimeter.

Absolutely and its this reason I love my vamo as it has a OHM checker
It works a treat and gives me a low cost entry into rebuilding my own coils!

A dedicated Ohm/Cartomizer reader are quite handy to have. Not only for getting more accurate readings on your build, but also for mounting and wicking your builds. The atty screw right on, and gives one a stable platform to mount the coils on. No more fumbling with the mounting base while tightening my leads. Can find them online for ~$20.
An eVic doesn't force a new check without putting it to sleep or shutting it off.
This is the reason people recommend shutting it off before screwing an atty on or else you may get a reading before you make complete contact. I know I've seen a .1Ω difference in my RBAs on an eVic that I thought shouldn't be there, reboot it and have it read right.
I've also seen it make a check on its own but I don't know what that criteria is, just that it's beyond a .1Ω tolerance.
Vamo doesn't do that, when you push the button it reads it.
This is not intended to be a testimonial to the accuracy of the ohm meter capability of the Evic, but a couple of things for clarification:
1. It has been my experience that the Evic does continually check the ohms of the device. No need to turn the Evic on and off or put it to sleep and wake it up.
2. The Evic has an atomizer sub-menu that either displays the last ohm reading or actually does a recheck. As I do believe the Evic continually checks the ohms of the device, it is probable that the sub-menu does in fact force a check.
3.An Evic will not read sub-ohms (i.e. under 1 ohm), it will display a device "short" message.

I forgot about that. I guess I find it easier to put it to sleep and wake it up than cycle through all the menu things.
I'm sure it continually checks. I use an RBA on one that is prone to change from 1.9Ω-2.1Ω. Sometimes it resets after auto-sleep but I'm sure I've seen it reset without being asleep.
But when the wick was new and it would drop to 1.8Ω I'd mess with it and it wouldn't reset without being put to sleep (didn't try the menu check to force one).
I just checked, it will read .9Ω, it's when you try to fire that it gives the atomizer short message. I was thinking it wouldn't read them also.
i like the stand alone ohm readers when rebuilding. but having it on the mod too is handy.
Addendum: Sorry, didn't see the above post.
Menu, device, atomizer ohms makes it re-check the attached device. At least it has on mine. Unscrewing and tightening also makes it recheck ohms. Mine has read as low as .7 ohms, just will not fire it.

Hopefully I remember that the next time my coil drops too far and needs tweaked
But when you're talking using one as a meter for building the eVic ways of forcing a new check aren't very convenient.
SVD wouldn't be so bad, Vamo is very tolerable.
That said I still use my multimeter, especially for dual coils and micros.
A dedicated atty checker would be nice but not the designs I've seen (I'd like smaller and round so I could turn the base to wrap).
Now I know the eVic does not recheck by going into the menu. I was cleaning my coil and it shorted to 1Ω. Went into the menu and it gave me the same "atomizer short" as if I tried to fire it and this was after I fixed the short. Put it to sleep and woke it up and it was 2Ω without messing with the coil.
my vamo was reading a 2.2 coil @ .5 then .8 ohms idk if it was screwed in all the way.
Never hurts to have a good auto ranging multimeter, check the ohms, then see how it compares to the APV reading.
