Functioning Mark X Science Tricorder featured in the Star Trek: Voyager episode "Living Witness". In the episode, the Doctor finds himself years in the future trying to defend the actions of the Voyager crew and their role in an alien civilization's history. This Tricorder has been heavily weathered by the production to look aged and can be screen matched to the episode. The body of the Tricorder is a medical version, with detachable hand scanner on the back, but features the graphics of a science Tricorder on the front. The hand scanner is machined from aluminum, with a beveled top and sequencing LED lights, a feature of the early Tricorder designs. The main body is made of vacuformed plastic, with applied graphics on the front and top. Item features full sequencing LED lights when the door of the Tricorder is opened. This piece was also re-used in Star Trek: Deep Space Nine. This item measures 6" x 3" x 1" when opened and remains in excellent condition.
