This is Carson Hill and I tattooing simultaneously on a collaborative piece--I'm using his very own 'Neuma' air-powered tattoo machine, and he's using my Pulse Gatsby coil machine. Funny, my fat grip is bigger than his whole machine, which is about the weight of a big marker, fully autoclavable, and by the way, works really well. Definitely worth checking out for a quiet, comfortable, extremely lightweight alternative to coil machines.
