The Equaliser Unicorn Max is a wireless rotary built around two stroke variants — 3.5mm for fast lining and detail work, or 4.2mm for shading and colour packing. Same machine, same battery system, same controls — pick the stroke that matches your everyday work. Two stroke variants — choose at purchase: 3.5mm (Liner variant) — fast, accurate line work and outlining. Quick, clean transitions, soft shading for realism artists. Good for fine line, single-needle, black-and-grey detail. 4.2mm (Shader variant) — needle hits harder, deeper ink deposit. Built for shading and colour filling, traditional saturation work, denser coverage in fewer passes. The variants share identical body, motor, battery system, and firmware — only the internal stroke geometry differs. Color LED display & glove-friendly buttons The display reads voltage, motor speed, and active voltage program at a glance — no stopping mid-tattoo to check settings. Buttons are precisely designed to be operable through gloves and after the machine is wrapped for hygiene compliance. Two batteries — 14 hours of work Ships with two batteries that combined give up to 14 hours of active tattooing. Run one while the other charges — no session interruption when battery 1 drains. Workhorse spec for convention work and marathon studio days. Adjustable needle protrusion Both variants have adjustable needle depth via front housing — useful when switching cartridges or moving between technique zones mid-session.
