Unlike most accessories, informational accessories such as the Goblin Tech do not need to be equipped in an accessory slot. The Goblin Tech may be carried in the player's inventory without loss of functionality, unless equipped to a social slot. Additionally, the info it provides will be shared with players of the same team in multiplayer that are within 50 tiles. Keep in mind modifiers will no longer apply to the player when not equipped.

The texture of Goblin Tech looks like the texture of its components put together.
Despite being called the "Goblin Tech", none of the components are obtained from a Goblin.
The Goblin Tech is one of the hardest items to get for the PDA, surpassed only by the Fish Finder, because of the fact that the Metal Detector only drops from Nymphs.
