Trying to mine large ore deposits in Subnautica 2 but getting hit with the dreaded “unknown tool required” message? You’ve officially reached the point where the Sonic Resonator becomes mandatory.
The Sonic Resonator is one of the most important early-game tools in Subnautica 2, letting you destroy large resource nodes, farm rare materials faster, and progress deeper into dangerous biomes. Without it, gathering advanced materials becomes painfully slow, especially once you start exploring tougher underwater regions filled with corrupted growths and hostile creatures.
Later on, you can upgrade it into the Feedback Resonator, which is required for clearing Bloom Cankers and unlocking major story progression. The upgraded version also gives you ranged sonic blasts, making dangerous exploration much safer in areas like the Alien Ruins and Metal Farms biome. Many players consider it one of the most valuable upgrades before entering the mid-to-late game zones.
Here’s exactly where to find the Sonic Resonator fragments, how to unlock the Feedback Resonator upgrade, and the fastest way to gather all required crafting materials so you can continue progressing through Subnautica 2 without getting stuck.
How To Unlock The Sonic Resonator In Subnautica 2
If you want to start mining large ore deposits in Subnautica 2, unlocking the Sonic Resonator should be one of your top priorities. This powerful mining tool is required for breaking advanced resource nodes that can’t be harvested with the standard Survival Multitool.
To get the Sonic Resonator in Subnautica 2, you’ll need to scan two Sonic Resonator fragments located inside the Old Habitat during the Quaker blackbox mission. Thankfully, both fragments are found in the same area, making this one of the easier early-game blueprint unlocks.
Once both fragments are scanned, the Sonic Resonator blueprint unlocks automatically, allowing you to craft the tool at a Fabricator. Many players rush this upgrade early because it dramatically improves resource farming and opens access to valuable materials needed for later progression.

Sonic Resonator Fragment Locations
Both Sonic Resonator fragments are located inside the Old Habitat biome.
Old Habitat Location
You can find the Old Habitat:
- Approximately 420m north-northwest of your Lifepod
- During the Quaker blackbox signal objective
- Through the rear entrance of the abandoned structure
The area is relatively safe compared to later biomes, though it’s still worth bringing extra oxygen and a charged battery before exploring.
Sonic Resonator Fragment #1
The first Sonic Resonator fragment is:
- Immediately to the right after entering the building
It’s fairly easy to spot near the entrance, especially if you keep your scanner equipped while moving through the habitat.
Sonic Resonator Fragment #2
The second Sonic Resonator fragment is:
- On the floor inside the next hallway corridor
A lot of players accidentally miss this fragment because it blends into the damaged flooring and scattered debris. If you don’t see it immediately, slow down and scan the ground carefully while moving through the corridor.
Sonic Resonator Crafting Recipe
After unlocking the blueprint, you can craft the Sonic Resonator using a Fabricator.
Sonic Resonator Materials
You’ll need:
- 1x Basic Battery
- 2x Titanium Ingot
- 2x Lead
- 1x Wiring Kit
Some players get temporarily stuck at this step because Titanium Ingots require a Processor before they can be crafted. If you haven’t built a Processor yet, make sure to unlock it first before gathering the remaining materials.
Once crafted, the Sonic Resonator lets you destroy large mineral deposits, making it one of the most important upgrades for efficient farming and mid-game progression in Subnautica 2.
What The Sonic Resonator Does
The Sonic Resonator is primarily used for breaking large ore deposits in Subnautica 2, making it one of the most important progression tools you can unlock early in the game. Before getting it, players are limited to smaller resource nodes, which can make crafting advanced equipment and base upgrades much slower.
Once you unlock the Sonic Resonator, resource farming becomes significantly easier because the tool can destroy advanced mineral deposits scattered throughout deeper biomes. It also helps speed up material collection for vehicles, upgrades, processors, and later-game technology.
The Sonic Resonator is mainly used for:
- Breaking large ore deposits
- Mining advanced resource nodes
- Farming rare materials faster
- Damaging smaller hostile creatures
- Clearing resource-heavy areas more efficiently
After crafting the tool, you’ll be able to mine:
- Titanium deposits
- Copper nodes
- Quartz veins
- Celestine deposits
- Enamel resources
Some players also use the sonic blast defensively against smaller aggressive creatures, since the impact can briefly stagger enemies during exploration.
Overall, the Sonic Resonator is basically your gateway to efficient mid-game farming in Subnautica 2. Without it, gathering high-tier crafting materials becomes much slower, especially once you begin exploring dangerous biomes tied to the main story progression.
How To Get The Feedback Resonator In Subnautica 2
The Feedback Resonator is the upgraded version of the Sonic Resonator in Subnautica 2, and it becomes incredibly important once you begin exploring the game’s more dangerous mid-game biomes. Unlike the standard Sonic Resonator, this upgraded tool can fire ranged sonic blasts, allowing players to destroy Bloom Cankers and corrupted obstacles from a safe distance.
Without the Feedback Resonator, progressing through certain alien-infested areas becomes much more difficult, especially in regions packed with hostile wildlife and environmental hazards.
This upgrade becomes especially important once you start exploring:
- Alien Ruins
- Tadpole Pens
- Metal Farms biome
To unlock the Feedback Resonator blueprint, you’ll need to scan two separate Feedback Resonator fragments hidden in different late-early-game locations.
Feedback Resonator Fragment Location #1
The first Feedback Resonator fragment is located near the Singh blackbox objective at the Cicada Wreck Therapy Room.
Exact Location
You can find the fragment:
- Roughly 770m east-southeast of the Alien Ruins marker
- Inside the Therapy Room structure near the wreck site
This area is deeper and far more dangerous than the Old Habitat region, so preparation matters before heading in.
Players strongly recommend bringing:
- A Tadpole vehicle
- Spare batteries
- Extra oxygen tanks
The underwater cave layout around this biome can become confusing very quickly, especially with limited visibility and multiple branching tunnels. Using beacons can help prevent getting lost while searching for the fragment.
Feedback Resonator Fragment Location #2
The second Feedback Resonator fragment is found inside the dangerous Metal Farms biome.
How To Find The Metal Farms
The Metal Farms biome is located:
- Northeast of the corrupted Angel Comb
- Near the giant alien turbine structure
You’ll know you’re approaching the correct area when you start noticing:
- Bright glowing green pools
- Corrupted terrain spreading across the seabed
- Heavy hostile creature activity
The Feedback Resonator fragment itself is usually found:
- On the ground
- Near the glowing pools
- Beside corrupted growth formations
A lot of players report a leviathan patrolling the upper section of the biome, which can make exploration extremely stressful if you surface too high. Because of this, many players prefer staying lower to the seabed while scanning the area for the fragment.
Once both fragments are scanned, the Feedback Resonator blueprint unlocks automatically, allowing you to craft the upgraded sonic mining tool and continue progressing deeper into Subnautica 2’s alien storyline.
Feedback Resonator Crafting Recipe
After scanning both Feedback Resonator fragments in Subnautica 2, head back to a Modification Station to upgrade your Sonic Resonator into the far more powerful Feedback Resonator.
This upgraded tool is essential for destroying Bloom Cankers, clearing corrupted pathways, and progressing deeper into the game’s alien-infested regions. Since the Feedback Resonator can fire ranged sonic blasts, it also makes dangerous exploration much safer compared to the standard mining tool.
Feedback Resonator Materials
To craft the Feedback Resonator, you’ll need:
- 1x Sonic Resonator
- 2x Enameled Glass
- 2x Conduit Crystal
- 2x Strontium
Some of these materials are easy to miss during normal exploration, especially Strontium and Conduit Crystals, which are mostly found in corrupted late-early-game biomes.
How To Get Enameled Glass
Enameled Glass is one of the easier crafting materials required for the Feedback Resonator upgrade.
To craft Enameled Glass, you need:
- Glass
- Creature Enamel
Creature Enamel is commonly found attached to rocky cliff walls and corrupted surfaces in deeper biomes. It usually appears as thick goo-like growths protruding from underwater rock formations.
Many players gather extra Creature Enamel while exploring the Alien Ruins since it’s also useful for other advanced crafting recipes later in the game.
How To Get Conduit Crystal
Conduit Crystals resemble glowing hardened seaweed or solidified coral strands.
The best places to farm Conduit Crystals are:
- Around corrupted Angel Comb tendrils
- Near Alien Ruins corruption zones
- Along infected biome pathways
These crystals are often hidden among corrupted plant growth, so scanning the environment carefully while exploring can save a lot of backtracking later.
How To Get Strontium In Subnautica 2
Strontium is one of the most confusing crafting materials for many players because it cannot be mined directly like normal resources.
Instead, you must first:
- Collect Celestine deposits
- Process Celestine inside the Processor
The Alien Ruins biome currently offers some of the best Celestine farming routes in Subnautica 2, making it the most reliable area for gathering materials needed to craft Strontium.
Because several advanced upgrades also require processed resources, many players recommend building a small outpost near the Alien Ruins to speed up farming runs and crafting preparation.
Why The Feedback Resonator Is Important
The Feedback Resonator is far more than just a stronger version of the Sonic Resonator in Subnautica 2. This upgrade is tied directly to story progression, advanced exploration, and several major late-game mechanics that players eventually need to complete the campaign.
While the standard Sonic Resonator is mainly used for mining large ore deposits, the Feedback Resonator adds ranged sonic blasts that allow you to safely destroy Bloom Cankers and corrupted alien growths from a distance. This becomes extremely important once you begin exploring dangerous biomes filled with environmental hazards and aggressive creatures.
You’ll eventually need the Feedback Resonator to:
- Destroy Bloom Cankers
- Access blocked alien pathways
- Unlock advanced Adaptation abilities
- Progress the Angel Comb storyline
- Understand alien language later in the campaign
Without this upgrade, several mid-to-late-game areas become extremely difficult to clear, and some progression paths are effectively locked behind corrupted environmental barriers.
Many players consider the Feedback Resonator one of the most important upgrades before fully exploring the Alien Ruins biome and surrounding corrupted regions.
Best Preparation Before Entering Alien Ruins
Before hunting for Feedback Resonator fragments, it’s a good idea to prepare properly. The Alien Ruins and Metal Farms biomes are significantly more dangerous than earlier exploration zones, especially if you’re still using basic equipment.
Most experienced players recommend:
- Building the Tadpole vehicle first
- Carrying multiple spare batteries
- Upgrading oxygen capacity
- Placing navigation beacons
- Saving before entering Metal Farms
The Metal Farms biome in particular is currently one of the more dangerous exploration zones in Subnautica 2 Early Access due to its aggressive wildlife, corrupted terrain, and limited visibility.
Setting up a temporary outpost near the Alien Ruins can also make resource farming and repeated exploration runs much easier.
