PUQ Prep Navigator – Automatic WDT / Distribution Tool

PUQ Prep Navigator – Automatic WDT / Distribution Tool

The PUQ Prep Navigator is an innovative, automated (WDT-style) distribution tool that standardizes the grind distribution process to achieve a more consistent puck structure and more reliable extractions. It simplifies the otherwise manual needle distribution step with a true one-touch mechanism. 

Technical features & specifications

• Capacity: approximately 500–800 cycles per battery charge, depending on the selected mode. 
• Dimensions: 10.5 × 9.5 × 5.0 cm 
• Weight: approx. 400 g 
• Distribution modes: Three different profiles – Standard, Speedy and Precision. 
• Delay Mode: The device can be set to have a short delay before activating – useful in multi-step workflows. 
• Needle options: Compatible with 18-20g and 20-22g baskets - needles can be adjusted according to the basket size. 
• Drive / Mechanism: Motorized “Randomness Mechanism” – includes a rotating ring and multiple needles that move in combination to provide more coverage and break up clumps. 
• Charging: USB-C lithium battery operation – therefore wireless use. 
• Warranty: 2-year manufacturer's warranty. 

Advantages & Areas of Application

• Even distribution & reduction of channeling: The automated movement gives you an even puck density and minimizes the risk of furrows or dense zones. 
• Reproducibility & standardization: Every coffee starts with the same distribution profile – ideal for shops where several baristas work or many shots are produced in a row. 
• Workflow optimization / efficiency: The device uses one-touch operation, so the distribution step is carried out quickly and easily – less manual variability. 
• Compact design: Despite its automatic nature, the Prep Navigator remains relatively compact and can be integrated into existing workflows. 
• Ideal for high-volume and specialty environments: When many shots are produced in succession, automation helps maintain consistent quality even under time pressure.
