Portable Scanners
Hand-held devices that can detect/analyze electromagnetic energy and other objects. The original expedition to Abydos used scanners to analyze the local food and minerals. Samantha Carter used a scanner to analyze electromagnetic energy emanating from the crystal skull in the episode "Crystal Skull". She also used a similar device to detect electromagnetic energy emanating from the android Reese when SG-1 discovered her in an alien tomb in the episode "Menace". In the episode "The Quest" Carter used a hand held scanner to detect the time displacement field as the team navigate their way through ancient trials towards the Sangraal.

Famous quotes containing the word portable:
“In the quilts I had found good objects—hospitable, warm, with soft edges yet resistant, with boundaries yet suggesting a continuous safe expanse, a field that could be bundled, a bundle that could be unfurled, portable equipment, light, washable, long-lasting, colorful, versatile, functional and ornamental, private and universal, mine and thine.”
—Radka Donnell-Vogt, U.S. quiltmaker. As quoted in Lives and Works, by Lynn F. Miller and Sally S. Swenson (1981)
