A Goa'uld automatic remote weapon approximately 12 centimeters in diameter, also known as a "tak", which senses motion and fires quick blasts of energy. Taks are hidden in an area as a security system, firing on unsuspecting trespassers when they approach.

Though the device is similar in design to a shock grenade, the two weapons perform very different functions.
