The Sonar Shaft is a super-arrow from the future. It was sent to Green Arrow by fans from the year 3000 AD. The trick’s sole appearance is in “The Case of the Super-Arrows” from 1958. This “super-sensitive” shaft hovers once fired and hones in on very loud noises, like sirens, crashes, and explosions. Apparently it sends a series of rings back to the archer in a code? This one baffles me a bit, quite frankly.
