The AER is now finally compatible with the latest GoPro HERO 9. Also backwards compatible with GoPro 4-8.
Note: This AER is not compatible with the Max Lens Mod.

Throw your GoPro® HERO 9 with AER.

Super easy to set up. You don't need to charge or calibrate it. The wings smoothly slide into each other, forming a solid stabilizing tail, and after you pop your GoPro® camera in the head you simply screw it all together.
