I have a question about spaced coils. Do I need to pulse a new spaced coil to see if it glows evenly? Obviously with contact coils one needs to get out the hot spots but I'm confused if it's needed with spaced. I thought I heard somewhere that they don't need to be. Therefore for the last month that I have been building these types of coils I would not even check it and I believe I had a decent vape. But today a guy in the vape shop got me all confused by telling me that they need to be checked if they glow evenly. I am using SS 316L 24G round wire. Please somebody shed some light onto this for me because I'm lost. Thank you.

Assuming you have no shorts, they'll glow evenly. It's not a bad idea to pulse a bit to burn off any impurities though. Sometimes I pulse, sometimes I don't.
Its just habit to fire the coil to see hotspots and generally how it fires. Depending on the wire gauge some wire moves around a bit, change shape(32gauge and thinner) so after you fire the coil some picking and prauding to get the shape back again. There is no need to fire the coil red hot at any time, that just degrades the wire. SS is a finicky wire that does degrade if its dry-fired too hot. Just dryburn till you see the cooties harden up then scrape, I have a glass dropper with water that I drip onto the hot SS coil and that cleans off the cooties quite well that are harder to scrape off.
With dual coils, you also want to ensure that they heat up "evenly" as in, each at the same rate as the other.
Do I need to see if they glow evenly, even if I am building the same build again, with me knowing exactly how many ohms it should be? For example the new coil now reads .24 before even using it and I knew that was how it was with my old build which was the same build. I'm wondering because in the case that the ohms are the same, that means I know that the coil legs are the same length and where they're supposed to be and the screws are tightened well. In that case can it be possible that the dual coil doesn't heat up evenly?
I build spaced coils and yes I do glow and check every coil. I had never had a problem until recently. I had a SS 316L 26 ga coil that read the right resistance, had no touching points yet for some reason always heated from one side to the middle instead of the middle out. It took a lot of work to get that one to glow semi-right and to this day I can't tell you why. My best guess is that particular section of wire was out of spec just enough to cause that issue. The result while using it was less than normal vapor production and one side of the wick darkened faster than the other. I ripped it out finally and built another exactly like it, and all was back to normal.
It also depends on if you got 2 wires into the same set screw area. 2 legs in the same screw can cause issues, clapton for example the wraps can shift in the set screw area and cause fluctuations especially using SS and TC so you remove the wraps so just core wire exposed.
If your sure the 2 coils are the same then reset the wires and maybe. I don't make very many dual coils, just twice the hassle sometimes. Get yourself some 34 gauge SS and build a simple single core clapton. Since my first clapton vape I'll not vape any single wire build any more. The wraps are juice channels that produce a great vape. The mod just registers the core so peeling the wraps back makes for a better connection. The wraps just transfer the heat and have nothing to do with resistance other than fluctuating if they shift.

I pulse my newly made spaced coils...just to make sure everything's working right.
Agreed, I only build spaced and pulse them to check if the coil is firing correctly and to burn off any impurities on the wire from manufacturing and the oil from my fingers when I build.
I guess I had a misconception SS 316L is medical grade steel and never comes with impurities. I heard that a while ago but I guess it's not true?
Maybe....but your hands come with impurities. Your little vape drawer comes with impurities. The dude at lightning Vapes or wherever comes with impurities.....
Seems to make good sense to pulse any coil to me. I guess its human nature to take shortcuts, but when rebuilding coils I never take shortcuts. I have a routine I follow since building my first coil.
I always check the ohm's before firing any coil. I pulse my coils to burn off any possible impurities on the wire. I also check to make sure my dual coils glow equally, middle out.
I always pulse period, tho I seldom need to tweak a spaced coil. I'm lazy and don't want to have to do it again so if I can avoid it with a simple 15 second added step from the get go...
I only thought spaced coils are completely different because I'm new to them. Spaced is a type of coil I really like now, especially because they take up more space than contact coils. I am learning new things all the time as I go along and I'm happy to learn them. I am so glad I did ask my question

That reminds me of a quote “If you don't have time to do it right, then you better make time to do it over.” or something close to that. Very true in most things, building coils included.
Spaced vs contact coils are personal preference. I prefer contact coils because they seem to last longer (more durable) from frequent re-wicking.I only thought spaced coils are completely different because I'm new to them.

I find with single or twisted I prefer spaced and with exotics it doesn't matter flavor wise. I've also discovered I prefer slightly spaced over the wider spaces I was originally using. Can't put my finger on why but I enjoy the resulting vape more.
That's so true that it's personal preference. Even though my spaced coils don't last nearly as long as contact, I don't mind it. I only rewick once before building a new coil so I am rebuilding about once a week.
See, I don't particularly like making coils. I do it when I have to. I've had one set of coils last me several months.
When I worked in a vape shop, many of my coworkers made new coils EVERY DAY. It was a serious hobby to them and they actually gained enjoyment from it.
Another reason, besides burning off impurities, is hot legs.
A couple pulses usually gets rid of them.
