Thank you so much to everyone that replied and for your suggestions and comments.
@TheTinMan1 I do have a multi meter and know how to read the resistance of coils with that, although thank you
@VapeyMama that may do the trick, although I was hoping that a kind of base may exist.

Lol to be completely honest, I don't know what I'm going on about either...
I made up this device in my mind with absolutely no hallucinogens and it was a Universal base with a 510 screw in connector like on the bottom of all or most tanks...
This would screw into your Ohm reader, then it would have different attachments for different sized coils like a 12mm screw in for Triton 2/ Melo/ Fury Tank 2 etc.
Then have more attachments for different sized coil bases, as there can't be more than 5.
You could then screw your RDA into this do your build, dry burn if needed, make sure your Ohm meter was reading ohms as expected then wick and assemble your RDA as if it was a shop purchased standard coil all ready for screwing into the tank of your choice.
While this was all happening you are then still able to vape on and use that tank without having to take the tank apart first just so you can use the base to do a build.
The only other way is have two of each tanks, as I have 2 Smok Big Baby Beasts.
Though having another 12 or so tanks makes this in uneconomically viable.
And if a device like this did exist, you would have a home made coil ready to go into your tank when needed
@Walt3 thank you for that interesting info.
If I had a design team and a shed load of dosh, I would start the project, I'm betting it would be a great seller.
Thank you all
