Transphase eradication rod

Goa'uld energy weapon capable of making visible and eradicating any object that is out of phase from normal sensory perception. It fires a powerful blast of energy, and is mounted with a search device capable of making invisible enemies visible -- including those utilizing a personal cloaking device as well as species that naturally exist out of phase, such as the Re'tu.

Several versions of this device have been stolen by the Tok'ra.
