Here is a wrist seismo. These are the kind that are worn by the cast members. The
ones used by guests and the ones sold in the store
didn't have the red on them. The watch has been "gutted" and a piece of silver duck tape has been put up against the screen to give the appearence of a monitor. Though you never got to see what the screen looked like when El Blanco was passing by it was supposed to show your location and where the Graboid was. Cool stuff
