FK Irons One Update Tattoo Machine 4.0mm Stroke - Tidal

Tidal is FK Irons' Limited Edition Artist Colour of the Year, here on the machine built to stay in your hand from first line to final pass. The One Update runs a fixed 4.0 mm stroke tuned to handle lining, shading and packing in one platform, so there's no swapping machines halfway through a piece.

Dual battery compatibility is what makes the difference over a long day - 5.5 to 6.5 hours per battery, with a spare in the box and fast recharge cycles so downtime stays minimal. The 1.1" LCD keeps your voltage and settings visible without breaking your workflow, adjustable in 0.2 V steps across a 5 to 12 V range. At 215 g it's balanced for control rather than lightness for its own sake, and it takes Ergo Shield grips directly for a quicker setup and a more natural hand position.
