When to pick which
Choose the General Dynamics Mission Systems Knifefish for maritime defense and national security operations where long-endurance underwater monitoring is critical. It is specifically engineered for naval mine countermeasures and hydrographic reconnaissance in deep-water or harbor environments. With a 16-hour runtime and a 770kg frame, it provides the stability and persistence required for large-scale seabed mapping that aerial drones cannot perform. This is the primary choice for government contractors or naval forces needing a heavy-duty AUV to clear shipping lanes of buried or bottom mines without risking manned vessels or divers.
Opt for the Exyn Technologies ExynAero when operating in GPS-denied indoor or underground environments, such as active mines, tunnels, or complex industrial facilities. Its core advantage lies in the ExynPak SDK and real-time SLAM capabilities, allowing it to navigate and map confined spaces autonomously without external positioning signals. At only 3.2kg with a 5m/s flight speed, it is highly portable and agile for rapid volumetric surveys or safety inspections in hazardous areas. This drone is the superior option for mining engineers and surveyors requiring high-fidelity 3D models of stopes or inaccessible voids.
