Usage Note
Sonda covers several technical 'probe' uses: a space probe (sonda espacial), a medical catheter or nasogastric tube (sonda nasogástrica), and a geological borehole. The verb sondear means to probe or poll, and sondeo (a poll or survey) comes from the same root. In everyday conversation, encuesta is preferred for an opinion poll.
