Canon's ring

The Canon's ring was a device used by the Canon.

Overview
These were small rings that were around the middle finger of the left hand. A simple wave over the device activated it with a red light shining on its surface indicating its use. A further wave seemed to designate target coordinates.

The effects of the ring created a bolt of electricity that slammed at a targeted location. Those near the discharge were rendered unconscious with the energy being described as someone being stunned by a Zat'nik'tel.


 * Its not known how the ring accomplished this task; whether it was by manipulating the atmosphere or through orbital satellites is unknown.

History
When SG-1 arrived on a planet where the inhabitants were terrorised by a Goa'uld possessed Unas servant of Sokar, they attempted to save the people offered as a sacrifice to the creature. However, the Canon arrived and activated his ring which stunned SG-1 allowing the villagers to capture them.


 * The rings design seemed similar to that of Goa'uld design but the episode did not state whether it was or another civilizations creation.
