Helios Cannot Use a Synthesis Scanner

Helios does not have the ability to use a synthesis scanner. Synthesis scanners are tools designed for specific warframes and weapons in Warframe, and Helios — which is a sentinel companion — is not equipped to operate them. Helios can equip other scanner types and perform its own scanning functions, but synthesis scanners fall outside its capability set.

If you want to use a synthesis scanner in Warframe, you need to equip it on your warframe directly or use a different sentinel that supports scanner mods. Understanding which tools work with which equipment saves you resources and mod slots.

Key Takeaways

  • Helios cannot equip or use synthesis scanners because sentinels have their own separate mod and weapon systems.
  • Synthesis scanners must be equipped on your warframe's gear wheel, not on a companion.
  • Helios can use the Codex Scanner and other sentinel-compatible scanners to scan enemies and objects.
  • If you want synthesis scanning capability, equip the synthesis scanner on your warframe and use Helios for other support tasks.

How Helios Scanning Works

Helios comes with built-in scanning functionality through its precept mods, which allow it to automatically scan enemies and objects during missions. This is different from synthesis scanners, which are tools you manually set up and use. Helios scans passively while you fight, adding entries to your Codex without requiring you to stop and aim.

The sentinel can equip scanner mods like the Codex Scanner, which enhance its scanning speed and range. These mods work within Helios's own mod system and do not conflict with your warframe's gear wheel or equipment slots. This makes Helios useful for filling out your Codex during regular gameplay without taking up your active tool slots.

What Synthesis Scanners Actually Do

A synthesis scanner is a one-handed scanning tool that you equip on your warframe's gear wheel. When you use it, you aim at an enemy or object and hold the scan button to collect data. Synthesis scanners are used primarily for the Cephalon Simaris synthesis system, which rewards you for scanning specific enemy types and objects across the star chart.

Because synthesis scanners occupy a gear slot on your warframe, not on a sentinel, they are incompatible with Helios or any other companion. Your warframe uses the scanner directly, and your sentinel provides support through its own mods and weapons. This separation keeps the two systems independent.

Sentinels That Can Help With Scanning

If scanning is important to your playstyle, Helios is still a solid choice because its passive scanning helps you build your Codex without active effort. Other sentinels like Djinn, Shade, and Carrier have different strengths — Djinn deals extra damage, Shade provides invisibility, and Carrier picks up ammo — but none of them can equip synthesis scanners either.

The choice between sentinels comes down to what you need during missions. If you want scanning plus another benefit, Helios gives you both automatic scanning and the Deconstructor melee weapon. If you need raw damage or survival tools, another sentinel may serve you better. Synthesis scanning always stays on your warframe, regardless of which sentinel you bring.

Using Both Helios and a Synthesis Scanner Together

You can absolutely use Helios and a synthesis scanner in the same mission. Equip the synthesis scanner on your warframe's gear wheel, and bring Helios as your sentinel. During the mission, Helios will scan enemies automatically through its precepts, while you manually use the synthesis scanner when you need to collect specific synthesis data.

This combination is actually efficient for players doing synthesis farming. Helios fills out your general Codex entries passively, while you focus the synthesis scanner on the specific enemy types Simaris is asking for. You get scanning coverage from both sources without any conflict or incompatibility.

Why Sentinels Cannot Use Synthesis Scanners

Sentinels in Warframe have their own isolated mod and weapon systems. They equip sentinel weapons, sentinel mods, and sentinel precepts — not warframe gear or tools. Synthesis scanners are classified as warframe gear, which is why they appear on your gear wheel and not in a sentinel's loadout screen.

This design keeps companion equipment separate from player equipment, preventing overlap and keeping each system balanced. If sentinels could use synthesis scanners, it would change how the scanning system works and potentially break the balance of the Cephalon Simaris farming loop. The separation is intentional and reflects how Warframe structures its equipment categories.

Frequently Asked Questions

Can I use a synthesis scanner if I bring Helios?

Yes. Equip the synthesis scanner on your warframe's gear wheel and bring Helios as your sentinel. They operate independently and do not interfere with each other. Helios scans automatically while you use the synthesis scanner manually when needed.

What scanner can Helios actually use?

Helios can equip the Codex Scanner and other sentinel-compatible scanner mods. These mods enhance its passive scanning ability. The Codex Scanner increases scan speed and range, making Helios more efficient at filling out your Codex during missions.

Do I need a synthesis scanner if I have Helios?

Not for general Codex filling — Helios handles that automatically. You only need a synthesis scanner if you are doing Cephalon Simaris synthesis farming, which requires you to scan specific enemy types for standing and rewards. Helios cannot complete synthesis tasks on its own.

Which sentinel is best for scanning?

Helios is the best choice if scanning is your priority, because it scans passively without requiring you to stop and aim. Other sentinels do not have scanning precepts, so Helios gives you scanning coverage plus whatever other support you need from a companion.
