Tool
Metal Detector

The official store describes beginning the needle search by hand with a metal detector, before belts, scanners and robotic arms take over more of the work.
Use and operation
- How to use it
- Use the detector’s own current feedback when searching manually. Keep track of what you have inspected; do not substitute a fixed coordinate list for the game’s signals.
Checks and decisions
- What to check
- If production has already packed hay into products, also inspect storage and scanner routes. The developer explains that needles can remain inside hay products, not only in loose hay.
