Scanner
The multitool Scanner is described as detecting resources essential for survival. It is the basic named scanning choice in the source's multitool exploration list.
How it works
The technology entry calls the Scanner a topographic survey and says it detects resources essential for survival. It lists Analysis Visor as an enhanced follow-up with detailed scans and Survey Device as a hotspot locating system.
When it helps
If you want to detect survival resources, the Scanner matches the stated function. For detailed scans or hotspot locating, compare the separate technologies listed in the same source.
The tradeoff
The source describes resource detection, while assigning detailed scans and hotspot location to other technologies.
Your next step
Check the Scanner's current multitool description, then compare the Visor if you need detailed scans.
