Those who are looking for an answer to the question «Can sonar detect scuba diving?» often ask the following questions:

- Ascending when scuba diving?
🌊 How is sonar used to detect underwater?
- By determining the time between the emission of the sound pulse and its reception, the transducer can determine the range and orientation of the object. Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales.
🌊 How is passive sonar used to detect submarines?
- Passive SONAR does not send out a sound wave. It can only listen for sounds. It can tell whether or not something is present by listening for sound waves from objects. Passive SONAR is the method used for detecting submarines by listening for the sound waves of the engines.

Jacques Cousteau and Emile Gagnan together invented the modern demand regulator used in underwater diving. Their invention allowed for the equipment known as the Aqualung, or self-contained underwater breathing apparatus (SCUBA), enabling safer and deeper dives.
