Survey Device
The Survey Device is identified as a hotspot locating system. It is a distinct multitool scanning option when your goal is to locate hotspots rather than perform the source-described detailed scans.
How it works
The source lists the Survey Device under multitool exploration and defense technology and describes it as a hotspot locating system. It does not name hotspot types, unlock requirements, or how the results appear in play.
When it helps
If you are looking for a hotspot, this listed function fits that task. If you need detailed scans instead, the same source assigns that capability to the Analysis Visor.
The tradeoff
The available description is limited to locating hotspots and does not explain coverage or other scan uses.
Your next step
