Available through WayneTech and can be upgraded to Sonic Shock Batarang. Tuned to match the frequency of Suicide Collars to lure enemies into traps. Has a very slow recharge time. Once thrown, the Sonic Batarang can be used to Detonate causing the the Batarang to explode causing a sonic shock knocking out the lured target. Sonic Batarangs cannot be used in the same area once a Sonic Shock Batarang has been detonated. Make sure to detonate the Sonic Shock Batarang only if the targeting reticule is yellow, or else it will simply short-circuit and fail to knock out any enemies.
