Transport rings remote
A device commonly worn on the arm or hand by Goa'uld and Jaffa, allowing remote activation of a transport ring device at the push of a button. The remote usually takes the form of a partial glove or hand armor, and is activated by pressing a large crystal on the center of the device.
Transport ring remotes can also be integrated into a Goa'uld hand device.
