PUQ Prep Navigator (Black) (10-0400-1)

Uneven grounds are the quiet cause of most channeling problems, and the PUQ Prep Navigator exists to fix that before the shot even starts. It's the first automatic coffee distributor of its kind: a one-touch WDT (Weiss Distribution Technique) tool that levels and de-clumps your dose in seconds, so every pull begins from the same perfectly prepped bed of coffee.

Why baristas reach for it

• Smart needle design: Each flattened needle is precisely angled to first break up clumps, then distribute grounds evenly — declumping left, distributing right, for clean extractions with no channeling.
• Randomized pattern, consistent results: A resistance-driven mechanism moves the needle bed in a randomized pattern across the coffee bed automatically, mimicking the finesse of a skilled hand-WDT without the human variability.
• Open-frame workflow: The open design lets you distribute mid-grind or adjust your dose without pulling the portafilter, and pairs with optional in-line kits to sit naturally under your grinder.
• Three distribution profiles: Choose Speedy (1.5s), Standard (3s), or Precise (5s) distribution speeds, plus an adjustable 0–10 second delay timer, to match your bar's pace.
• Interchangeable needle rings: Ships with rings for both 18–20g and 20–22g baskets, so one unit adapts to your dosing without buying a second tool.
• USB-C rechargeable: A built-in lithium battery delivers 500–800 cycles per charge depending on mode, with a simple USB-C top-up between shifts.
• CNC-machined for daily use: Built like the rest of the PUQ Press lineup — sturdy, intuitive, and made to withstand thousands of cycles behind a busy bar.

Whether it's anchoring a high-volume café workflow or tightening up dosing consistency at home, the Navigator turns distribution from a manual guessing game into a repeatable step — freeing you up to focus on dialing in flavor instead of babysitting the puck.
