In Subnautica, upgrading your vehicles with sonar and depth modules is essential for exploring deeper biomes safely and effectively. To achieve this, you’ll be utilizing the Vehicle Upgrade Console and the Modification Station. Here’s a comprehensive guide on how to install these important upgrades for your vehicles.

Vehicle Sonar Module

Overview:
– The Sonar Module is a valuable upgrade that sends out sonar pulses to map your surroundings, helping you locate terrain features and hidden areas, particularly in dark or dense regions of the ocean.

Crafting:
– The Sonar Module can be crafted using the Modification Station.
– Once crafted, you need to equip the module to your vehicle (Seamoth, Prawn Suit, or Cyclops) via the vehicle upgrade interface.

Activation:
– When activated, the sonar emits pulses approximately every 5 seconds, consuming power with each pulse. In the case of the Cyclops, the sonar pulses are emitted automatically while active, leading to a drain on your energy reserves.

Depth Modules

Purpose:
Depth modules enhance the maximum depth that your vehicle can reach without suffering damage. Each vehicle has its own set of depth modules, which can be progressively unlocked and crafted.

Seamoth Depth Modules:
– Mark 1: Increases depth from 200m to 300m.
– Mark 2: Increases depth to 500m.
– Mark 3: Expands the maximum depth to 900m.

– You can initially craft the Mark 1 module after finding it in the Aurora’s Seamoth bay. To craft the Mark 2 and 3, you will need to discover their blueprints through the Vehicle Upgrade Console and then craft them at the Modification Station.

Cyclops Depth Modules:
– Default: 500m maximum depth.
– Mark 1: Increases to 900m.
– Mark 2: Expands to 1,300m.
– Mark 3: Maxes out at 1,700m.

– Similar to the Seamoth, the Cyclops requires crafting at the Modification Station for Mark 2 and 3 modules, while the Mark 1 module can be fabricated within the Cyclops upgrade fabricator.

Prawn Suit Depth Modules:
– Like the Seamoth and Cyclops, the Prawn Suit also has corresponding depth modules that can be upgraded similarly to ensure it can withstand greater pressures as you dive deeper.

Steps to Upgrade Your Vehicles for Depth and Sonar

1. Find the Vehicle Upgrade Console Blueprint: Locate this blueprint in databoxes found in wrecks, such as those in the Sparse Reef biome.

2. Build the Vehicle Upgrade Console: Construct this at your Moon Pool base to start unlocking depth module blueprints.

3. Construct a Modification Station: Establish this at your base, as it is necessary for crafting the depth and sonar modules.

4. Unlock Depth Module Blueprints: Use the Vehicle Upgrade Console to unlock the blueprints for the different depth modules.

5. Craft Depth Modules: At the Modification Station, create the depth modules (Mark 1, 2, and 3) and install them in your respective vehicles.

6. Craft the Sonar Module: Also at the Modification Station, craft the Sonar Module and equip it onto your vehicles.

7. Activate the Sonar Module: In-game, activate the sonar module to assist in navigating and exploring deeper ocean biomes safely.

Conclusion

By following these steps and upgrading your vehicles with sonar and the appropriate depth modules, you will enhance your capabilities for exploring the intricate and often treacherous depths of the Subnautica ocean. These upgrades are not just about extending your reach; they also significantly improve your navigation and safety during your underwater adventures, allowing you to delve into thrilling new biomes with confidence. Happy exploring!
