Ore Detector Reborn

First release for Minecraft 1.21 and 1.21.1 — one file covers both.

Eleven handheld ore detectors — Iron, Gold, Diamond, Emerald, Quartz, Copper, Coal, Amethyst, Netherite, Lapis Lazuli and Redstone. Right-click a surface and the detector scans into it and reports what it finds in the action bar, tinted to the ore's color.

• Directional scanning — 16 blocks down, 8 sideways or up, across a configurable column.
• Exact counts, not a vague hint: "Detected 4 Iron Ore nearby".
• Durability and repair — 1 use per scan plus 1 per ore found; repair in an anvil with the detector's own material; Mending and Unbreaking both work.
• Per-detector cooldowns — using one detector never puts your others on cooldown.
• In-game config via Cloth Config, from the Config button in the mods list: reach, column radius, cooldown, durability multiplier and beep volume, all bounded.
• Sculk sensors hear the beep, so mind where you scan in an Ancient City.
