Coil Tattoo guns are the most preferred choice among tattoo artists. These modern machines have a needle grouping that uses an electromagnetic circuit to move, entering the skin when the circuit is completed and retracting when it is broken.
Coil Tattoo machines are available in single coil, double coil or triple helix options. The standard one being the double coiled machine. The coil size also varies from eight to ten wrap options that then controls the power and the speed of the machines. This has a direct effect on the trauma on the skin. One of the caveats of a coil machine is that you will have to dismantle it completely before placing in the autoclave to sterilize it.
