Building a better Coil

Hola folks. I'm new around these parts.

So I'm getting a 180 Watt god mod for Christmas and I realized I'd like to be able to build a coil that doesn't suck.
My current coils are basically poorly wrapped cobbled together strips of wire that barely heat up..and usually not at the same time. (dual coils)
I watched some videos and the basic gist i got from them was that I need to wrap the coils closer together or tighter? I'm not quite sure exactly what it is that makes the coils go down in ohms. At first I thought it was less wraps. So i decided to go down to .4 and i only had 3 wraps on each and barely ANY coverage. Even though my Ohms were low i was getting LESS vapor production.

Most of the videos on youtube were guys showing off their coils with bad camera angles and way too much talking about themselves and their vapes.

SO i figured I'd get it right from you guys. What is it that makes a coil epic? Is it the amount of wraps? The Tightness? The type of gauge wire?

The type of wire, the gauge of the wire, the # of wraps, the spacing between the wraps, & the diameter of the tool you use to wrap the coil on.

Learn to do a single coil well before you start working on dual coils. How to Build a Micro Coil

Here are a few links for you regarding building coils and getting the resistance just where you want it:
1. Steam Engine
2. Coil Toy Calculator

Make sure to check your build with an ohm reader or DMM before putting it on your mod and firing it.

The gauge wire, type of wire, open / spaced or compressed coil, inside diameter, simple single wire or twisted or braided, round or flat wire, number of loops / wraps in each coil, amount of coils 1 ~8, height from deck, distance from air hole, coil to wicking material surface area, wicking material choice, resistance.

I'd practice building dang near perfect .8 - 1 ohm single coils until you can do it with your eyes closed then experiment with the variables.

The main thing in making decent vapour producing coils for a regulated mod is contact area between the coil and the wick. Obviously temperature plays a part, but as you have experienced with your low ohm 3 wrap coil, the high heat with low surface area does not produce good results.

The thicker the wire the more contact area there is per wrap (simple maths to prove this), for example my preferred single coil setup is 22AWG (0.6mm) wire with 7 wraps 0.5ohm, this has the same contact area as a 3ohm 28AWG (0.3mm) coil. Thicker wire does require more power to heat up than thinner wire and also cools down more slowly.

As you are using a regulated mod you can vary the power going to the coils which will vary the heat produced (and warmup time), this coupled with large contact area will produce decent clouds, you will also be able to fine tune your vape so that it ticks all your vaping boxes.

I've had experience with various types of wire. The higher the AWG+thickness, the more it drains your batteries quickly.

I think you mean the lower the AWG.

Yes, it does drain your battery quicker if you build with low AWG compared to a higher AWG wire, but that only matters with a mech mod. The OP is getting a regulated mod, therefore can control the wattage regardless of coil resistance. Also the GOD MOD I think takes 3 batteries, so there is less of a need to be conservative on the use of watts.
