The Kwadron Equaliser Neutron II takes everything you loved about the original Neutron and ramps, or should we say “clicks”, it up a notch. Equipped with a quick click-adjustable stroke range of 2.6 - 4.0mm, the Neutron II pen offers something most pens double its price don’t; flexibility. You no longer need to buy 2 or even 3 machines to ensure precision work, regardless of technique or style, just click and go. If that wasn't enough, it's lighter and more ergonomic, and includes additional artist-approved features like 4 voltage presets and a session timer.. The Neutron II also got a bit of a facelift. An all-new colour display not only provides a clearer view of your voltage settings, but the added orientation adjustment conforms the machine to you, instead of the other way around. Left handed artists rejoice! SMP/DOT WORK Mode: Perfect for dotwork and scalp micropigmentation, with full adjustment capabilities for needle stroke and frequency.
