Investigator is a mod that allows the Helios Sentinel to scan objects and enemies it encounters. This consumes Codex Scanner, or Synthesis Scanner charges.


Rank Range (m) Duration (s) Cost
0 +20m +5.0s 4
1 +26m +4.4s 5
2 +32m +3.8s 6
3 +38m +3.2s 7
4 +44m +2.6s 8
5 +50m +2.0s 9


  • Helios' scans will not give the player Simaris standing, even if Synthesis Scanner charges were used, however each scan will reward the player with affinity, like a normal Codex Scanner use would.
  • You must have a Codex Scanner or Synthesis Scanner equipped in your gear for Helios to use scan charges from; there is no warning if you go into a mission without any charges (Helios will just not scan anything).
    • The order of scanner usage is Codex Scanners then Synthesis Scanners. Once you are out of Codex Scanners, Helios will begin to consume Synthesis Scanners.
  • It will not scan targets with complete codex entries.
  • If one has a Sol-Battery Widget, these scans will not drain charges from the Synthesis Scanners, allowing for free scanning. (Make sure to not equip any Codex Scanners, since Codex Scanners are consumed first regardless of Sol-Battery Widget.)

Patch HistoryEdit

Hotfix 22.17.4
  • Optimized Helios' Investigator Precept: it should now find targets more than 10x faster and no longer causes periodic spikes in frame-time as high as 7ms.

Hotfix 19.6.3

  • Fixed the Investigator Mod description showing unrounded duration values.

Update 13.3

  • Fixed Helios' Investigator Precept not properly displaying/calculating its max rank and perpetually behaving like a rank 0 mod. It will also receive a target lock so it doesn’t Get distracted during scans so easily.

Update 12.5

  • Introduced.
