The Sonar Gun, while still a conceptual design, is the tool players would use to find necessary resources spread throughout the map. It fires a sonar/magnetic pulse in the aimed direction and then receives and displays feedback from the pulse on its conical radar screen. It is tuned to specific raw material types such as carbonate, oxide, sulfide, silicate or ice that are located on the surface of Mars. It's primary use is for harvesting crafting materials.
