Seamoth Sonar Module
The Seamoth Sonar Module passively scans nearby terrain and marks locations of interest on your HUD, making it easier to navigate unexplored biomes and locate wrecks, fragments, and resource nodes.
Quick Info
Description
The Seamoth Sonar Module is a passive mapping upgrade that continuously scans the area around the Seamoth. It highlights the outline of nearby terrain and places markers over points of interest such as wrecks, fragment caches, and resource outcrops, helping you chart unfamiliar biomes and plan return trips with confidence. The data is saved to your vehicle, so the marks persist between dives.
