Multi-ore Detector

Multi-ore Detector emits a pulse that reveals all ores nearby, even if they are hidden from sight (behind the blocks, in a non-illuminated area, etc.). Blocks that contain the ore are colored/illuminated (different colors for different ores), but this only lasts for a very short time.

If you upgrade this tool, the range of pulses will increase. It will also start detecting higher-tier ores (it can't detect most ores at tier 1, and some ores at tier 2).

If you are searching for one specific ore (e.g. Titanium Ore or Diamonds), it may be more convenient to use Precision Ore Detector instead (it won't notify you about ores that you are currently not interested in).
