How to say "probe" in Japanese

• 探査たんさCommon
  noun, suru verb, transitive verbCovers 'probe' as a systematic exploration or investigation — scientific probing of space, the seabed, or another unexplored domain — so it often reads as 'exploration' or 'inquiry' rather than a physical instrument.
• 探りさぐりCommon
  nounCovers 'probe' as a hands-on act: sounding depths with a slender probe or stylet, or figuratively sounding a person out for their true intentions; not the word for a formal investigation.

Choose 探査 for 'probe' meaning a systematic exploration or investigation, and 「探り」 for the act of probing or sounding — feeling depths, using a probe instrument, or discreetly sounding someone out.
