So, basically like a bat?Curse you! D: You do know what sonar is right? Send a sound wave, when it hits an object and bounces back telling you the location of the object. Send it in quick succession to figure out its movement patterns etc xD inner sonar is more effective in water(as vibrations are easily transferred when molecules are close to each other) and ineffective in earth (as everything is solid, however you could simply detect the vibrations without using a sonar) @_@ now go ahead
*I close my eyes and take a spin, as I forget my surroundings.*
*I channel my sound chakra into my gullet, and emits a sound wave from my mouth. It travels forward and hits a tree, and bounces back to me, allowing me to know exactly where the tree is.*
