To produce a screen accurate replica of the Motion Tracker, Hollywood Collectibles Group first had to track down all of the original components that the prop master for Aliens, Terry Reed, used to make the original. This included the correct Kango 426 hammer drill casing and Hama slide viewer. Using these parts, accurate prototypes were built to enable the production of a replica that is faithful to the prop seen in the movie. Constructed using a thick, high quality, injection molded polymer case, metal and other mixed media (just like the original), the Motion Tracker replica also features authentic working electronics and sound! A press of the button and the video sequence starts with the Aliens closing in, and the "beeps" getting ever closer together. Includes a table top display stand.
