Most professional tattoo shops use dual coil tattoo machines because they are readily available and relatively inexpensive. They also provide smooth lines and shading.
We get in a lot of tattoo machines at Supernova and serve a lot of you artists out there, yall are great. You know we carry all these tattoo machines, but for you new guys… let be break it down to you. From what I've gathered each tattoo machine is like a little car. They all perform a little differently and most artists have a few that are their “main boo” and then a couple on the side they like to break out for specific projects. I think we have a machine for every occasion.
Plus you know you've got to have a back-up on hand as well, so we tend to have quite a few and in a variety of styles. These ones here are just the basic models, we have other ones that are pretty fancy and some of the rotary machines as well, so that's pretty cool.
