The device Daniel Jackson uses to evaluate the artifacts inside the museum's deposit is, actually, a GPS unit, a Garmin eTrex.
Three characters in this episode share a surname with members of the Green Lantern Corp from DC Comics: Dr. David Jordan (Hal Jordan), Dr. Sarah Gardner (Guy Gardner) and Dr. Steven Rayner (Kyle Rayner).
The scene where Daniel sees something of interest in the newspaper Jack is reading, and snatches it away, is a callback to his same action in the original film Stargate (1994).
