Dynamics for Every Movement

According to the manufacturer, the MCORE Pro motor delivers 40% more penetration force compared to the previous generation. Combined with a 4.2 mm stroke length, it provides enough impact even for more demanding tasks. Stable operation also allows confident handling and creates suitable conditions for smooth and precise tattooing.

One System. More Ways to Use It.

Mastlabs E-System offers two control options. HZ mode operates within a range of 3–140 Hz, maintains consistent power, and lets you match the frequency to your hand speed. It also contributes to better color saturation and a smoother tattooing process. DCV mode is based on traditional voltage control and remains effective even at lower voltage levels.

You can choose from:

- Soft / Medium / Hard – three levels suitable for different styles and methods, from fine line and dotwork to lining, Black & Grey, realism, and solid fills
- Dots – individual dots below 15 Hz
- 3–15 Hz – recommended values for SMP with 1RL/3RL

Less Downtime Throughout the Day

The 1,520 mAh battery provides up to five hours of runtime, while a full charge takes approximately 40 minutes. MAST Ultra Fast technology can also provide enough energy for about one hour of operation after just five minutes when used with a compatible charging dock.

The 0.85" HD color display with 213 PPI resolution shows important information:

1. selected HZ/DCV mode
2. current frequency or voltage
3. Soft/Medium/Hard level
4. battery status
5. time
6. Bluetooth connection

Bluetooth also connects the device to the Dragonhawk app and a wireless foot pedal.

Ergonomics Designed for Comfort

Placing the battery inside the grip shifts the center of gravity downward, which supports easier handling and precise control. Well-balanced proportions also help reduce hand strain during longer sessions.

• Length 115 mm – practical dimensions
• Grip diameter 33 mm – stable hold
• Weight 170 g – easier handling

Professional equipment should complement your experience while giving you room to explore different approaches. What matters is not only immediate functionality but also the confidence that your investment will meet your expectations in the future.

Mast Racer Pro 4.2 mm is a solution for tattoo artists looking for long-term value without making unnecessary compromises as they continue to develop.
