Find The Needle metal detector manual needle search comes down to one tool: the Metal Detector finds needles by hand in the pile, before belts, scanners and robotic arms take the searching over. It is listed among the needle detection tools rather than the hay tools, so it plays a different role from the shovel and the pitchfork.
Find The Needle metal detector manual needle search: what it does
- It detects needles inside the hay pile while you carry it, which is what makes the first needles findable before any machine exists.
- It is a reconnaissance tool rather than a production tool. You can keep carrying it and patrol around the haystack to work out which side of the pile holds the needles.
- It has a hard limit: most needles are buried too deep for it. As the factory grows it becomes impossible to check everything by hand.
- It does not protect the sale point. A hay wad packed by the Silo can hide a needle, so a fully scanned pile still has to be watched where it is sold.
Once the pile gets big enough that patrolling it by hand stops being practical, scanners take over detection and the detector keeps its scouting job.
How to use it before you automate
- Carry it around the pile early on and note where the needles turn up. That tells you which side of the hay to dig first.
- Do not expect it to find every needle. Treat a clean patch of pile as "not found yet", not "empty".
- Watch the sale point as well as the pile. A needle packed into a product can leave the factory without the detector ever being involved.
- Replace it with scanners as soon as you can. One detector cannot cover a pile of six million strands, and the pile keeps growing. The tool order that gets you there fastest is in which manual tools to buy first.
