Ground-penetrating scanner

Ground-penetrating scanner

A sensor unit used by researchers to search for buried resources. The chance to find a resource depends on the operator's research ability. It consumes a lot of electricity. If you find a buried resource, you'll need to use deep drills to extract it. It doesn't work under a roof.

A ground-penetrating scanner detects and illuminates underground deposits of resources, either jade or metals. Extracting materials from these deposits requires a deep drill.

The Ground-penetrating scanner project must be researched before it becomes available, and needs power to function. A scanner is one of the most power-hungry devices. During operation, a researcher will work at it, periodically finding new mineral deposits. This process can repeat indefinitely meaning that maps will not run out of resources.

The ground-penetrating scanner is not usable if there is a roof over it. (Similar to the long-range mineral scanner.) If necessary (such as in an extreme environment) the ground penetrating scanner can be placed in a room with at least 24 tiles, with the nine tiles it occupied being unroofed. This allows the room to be heated, although inefficiently, without the temperature immediately equalizing to the outdoor temperature. Having a larger room with double-thick walls allows for more efficient heating.

The mean time between finding deposits is 3 pawn-days of scanning, with a guaranteed find after 6. These values are further modified by the Research Speed of the user.


Ground-penetrating scanners can be constructed once the Ground-penetrating scanner research project has been completed. They require Steel 150 Steel, Component 4 Component, Advanced component 1 Advanced component, 12,000 ticks (3.33 mins) of work, and a Construction skill of 8.


The resources contained in a deposit correlates with the size of the deposit. Each cell of resources contains 300 units of the resource. Below is an estimate of the different deposit sizes:

  • Resource Deposit Size Deposit Mean Commonality Portion Size Avg Deposit Return
    Steel Steel 20 - 40 ~ 30 4 35 Steel 9000
    Silver Silver 7 - 20 ~ 14 0.5 40 Silver 4200
    Plasteel Plasteel 2 - 10 ~ 7 1 7 Plasteel 2100
    Jade Jade 1 - 5 ~ 3 0.5 10 Jade 900
    Gold Gold 1 - 5 ~ 3 0.5 10 Gold 900
    Uranium Uranium 4 - 10 ~ 7 1 10 Uranium 2100

  • Version history

    • Beta 19 - power usage was significantly reduced from 1500W to 800W. Its build cost was also changed, previously costing 400 steel and 12 components.
    • 1.1.0 - Reworked; previously it showed all minerals on the map instantly. Now it requires work by a pawn and will periodically find new mineral patches, forever. Its power cost was also slightly lowered to 700W.
    • 1.1.2564 - Rebalance. Random find time 4 work days->3 work days. Guaranteed find time 8 work days -> 6 work days. Now displays feedback about the current user's scanning speed, the random scan interval for this user, and the progress to a guaranteed find.
