The PUQ Prep Navigator is an automatic coffee doser that simplifies one of the most important steps in espresso preparation. It helps distribute the ground coffee evenly in the basket before tamping, so every shot starts with a better-prepared and leveled puck. With one-touch control, it eliminates the guesswork and variability of manual distribution—a feature you’ll especially appreciate when you want more consistent extraction, a faster workflow, and less room for error. It’s ideal for both busy cafes and home baristas who want greater control over their espresso preparation.
Inside, an advanced needle system standardizes coffee distribution and helps you fully utilize the grinder’s potential. The Navigator offers three distribution profiles—Standard, Speedy, and Precision—so you can choose your working style based on whether speed, precision, or a balanced compromise is more important to you. It also features a delay mode and interchangeable needles for 18–20 g and 20–22 g baskets, allowing the grinder to better adapt to various recipes and daily use.
The device is powered by a lithium battery with USB-C charging and can handle approximately 500–800 cycles on a single charge, depending on the selected mode. Its compact dimensions of 10.5 × 9.5 × 5 cm and weight of 400 g make it a practical tool that doesn’t take up much space on the bar but can significantly improve the precision of your preparations.
