Subnautica 2: Unlocking and Upgrading the Sound Resonator – Here’s How

In Subnautica 2 is one of the most important tools in the game the sonar resonator, but you first have to unlock it. What it brings you and how you can get and unlock it, you can find out here. 

What can the sonar resonator do? With the sonar resonator, you can, as the name suggests, produce sound and fire at things nearby. Living beings can be briefly stunned, while rock formations and solid mineral deposits can be harvested or destroyed.

Especially for harvesting important materials, the sonar resonator is indispensable. Many rare resources can only be harvested with it, such as the conduit crystals near the alien ruins.

However, the sonar resonator has a catch; you have to get very close to your targets to produce an effect when firing. However, there is also an alternative – the feedback resonator. This can send its sound waves traveling and thus hit distant targets with ease.

We will now show you how to obtain both devices as simply as possible.

Unlocking the sonar resonator

How do I unlock the sonar resonator? To unlock the sonar resonator, you need to scan a total of 2 scattered specimens. After that, you will receive the blueprint for the device. These devices are often found scattered around ruins or crash sites in containers or facilities. One of the best places to find them is the “Old Base”. You can pin this with a signal marker and swim or drive there – it is located in the northwest of the map.

Once there, you need to go inside the base and look on the floor or tables in the various rooms. In the area, you will find two sonar resonators and can unlock the blueprint in one go.

Upgrading the sonar resonator

How can I upgrade the sonar resonator? The sonar resonator is the first stage of the device, but there is also the upgrade: the feedback resonator. Again, you need to scan 2 specimens of this type. One can be found near the alien ruins southeast of the research outpost – keep to direction 110 on the compass.

It is advisable to take a depth module with you if you are traveling with the tadpole, as you will need to dive very deep. Keep the course and swim about 700 meters in that direction until you discover an alien wreck with an open door. Go inside and scan the first feedback resonator.

Now, exit the wreck and orient your compass north. Follow the path further down until you see a white-glowing cave on your right. Approach this and look on the ground. There should also be another specimen of the resonator.

Once you have scanned both specimens, you can now also craft the upgrade. To do this, you need:

• 1x sonar resonator
• 2x conduit crystal
• 2x enameled glass
• 2x strontium

These were all the important details on how to craft the sonar resonator and its upgrade. In Subnautica 2, there are many things you can explore, and not all important materials can be easily found.
