The Equaliser Ink Master is a wireless rotary tattoo machine that lets you pick your stroke at purchase — 3.5mm for lining and fine work, or 4.2mm for shading and colour packing. Same machine body, same battery system, same control modes — different drive configuration tuned to how you actually tattoo. Two stroke variants — pick the one that fits your style: 3.5mm (Liner variant) — fast, precise line work, soft shading, fine detail. The all-arounder middle ground for artists doing realism, single-needle outlines, or mixed black-and-grey sessions. 4.2mm (Shader/Packer variant) — heavier needle impact, deeper ink deposit, faster saturation. Built for bold lining, traditional colour packing, and dense shading. The variants share identical body, motor, battery system, and firmware — the only difference is internal stroke geometry. Pick the one that matches your everyday work. Three control modes — switch with two clicks M1, M2, and M3 modes give you three pre-tuned configurations that change how the motor responds to voltage and resistance. Switch between them with a quick double-click — useful when you want to move between technique presets within a single session without re-dialing voltage from scratch. Colour LED display The integrated display reads out: Current voltage Battery level for both packs Active mode (M1 / M2 / M3) Cumulative session work time Easy to read mid-tattoo without rotating the machine or pausing. Two batteries — 16 hours of continuous work Ships with two batteries that combined give up to 16 hours of active tattooing. Run one, charge the other — no session interruption when battery one drains. The hot-swap workflow is what makes this machine viable for convention work and long appointment days. Adjustable needle protrusion. Dial in needle depth via the front housing — useful when switching cartridges or moving between line work and shading mid-session.
