Seamoth Sonar

The Seamoth Sonar Module is an Seamoth and in-development Upgrade Module that allow the player to navigate underwater.

Trivia
Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation to navigate under the surface of the water. Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes, which this module for the seamoth uses.
