Five steps from entering the water to having a complete, shareable cave map.
Attach the compact Depthline sonar unit to your BCD or scooter. It pairs automatically with the Depthline app on your dive computer or waterproof tablet. No complex setup — power on and go.
As you move through the cave, the sonar module continuously captures passage geometry — walls, ceiling, floor, restrictions, and open chambers. Data records locally at 20 scans per second.
Back on the surface, sync your sonar data. Our AI stitches thousands of individual sonar pings into a coherent 3D model, identifies hazards, and calculates passage dimensions — usually in under 5 minutes.
Open your completed cave map in the Depthline viewer. Fly through passages, measure distances, identify points of interest, and see hazard zones. Overlay your depth and gas profiles from the dive.
Share your map with dive partners, publish it to the Community Cave Atlas, or keep it private. Every map you contribute makes the atlas better for the entire dive community.
Purpose-built sonar and AI for the unique challenges of underwater cave environments.
Our AI reconstructs cave geometry from raw sonar echoes using neural networks trained on thousands of real cave scans. The result: complete 3D models, even from partial data.
The Depthline module uses a 128-beam array to capture wide-angle cave profiles in a single sweep. Higher resolution than traditional single-beam units, purpose-built for confined spaces.
Our algorithms detect water flow patterns and silting risk from sonar return signals, flagging areas where visibility could degrade rapidly during a dive.
