The extra-large LED display — everything visible, nothing to interrupt

The extra-large colour LED display on the Unicorn Max is the largest in the entire Equaliser range — and it has a clear purpose: allowing the artist to check every key parameter without stopping tattooing. Current voltage, motor speed and active voltage programme — all visible at a glance, without leaning in, without rotating the machine, without interrupting the workflow.

The buttons designed for use with gloves make sure adjustments can be made at any point in the session — even with busy hands and without removing protective gloves.

Speed control independent from power — the innovation that makes the difference

This is the most relevant technical feature of the Unicorn Max and the one that separates it from most machines on the market. In a conventional machine, reducing speed means reducing power — and therefore the needle's penetration force. In the Unicorn Max, speed and power are independent parameters.

You can lower the speed for smooth, precise shading without losing any insertion force. Or increase speed for fast, dynamic lines while maintaining the same constant power. The machine always works with the same power regardless of rotation speed — which guarantees precise and deep ink deposition in every movement, at any speed.

14 hours of autonomy — the longest in the Equaliser range

With two included batteries that together provide up to 14 hours of uninterrupted work, the Unicorn Max is the wireless machine with the longest autonomy in the entire Equaliser range. For multi-day conventions, marathon sessions or guest spot days where power cannot become a limitation. The two interchangeable battery system ensures there is always one ready while the other is charging — zero downtime throughout the day.

The 4.2 mm stroke — techniques and styles

The 4.2 mm stroke is the reference stroke for intense colour work and lines with presence:

Colour packing and colour fills — long stroke that helps achieve deep, saturated pigment deposition in fewer passes.
Neo traditional and American traditional — thick outlines and dense fills that need power and depth.
Blackwork and geometry — solid black fills with even and consistent coverage.
Soft shading — thanks to independent speed control, the 4.2 mm stroke can also work for soft shading by lowering speed without losing power.

Kwadron Equaliser — The Polish reference in rotary machines

Kwadron is the Polish brand recognised worldwide for tattoo cartridges and tattoo machines. Its Equaliser line represents its commitment to high-performance rotary machines. The Unicorn Max 4.2 is its most technologically advanced machine: extra-large display, speed control independent from power and 14 hours of autonomy — a level of innovation that very few brands on the market can match.
