Advanced Design for Easy Configuration
- Small A-frame and winch support towing survey, cable length up to 200 meters;
- Foldable lifter protects instruments wet ends and offers greater payload capacity.

Stable Working Condition for Survey
- Excellent stability,roll range smaller than 10 degrees in SS4.
- Catamaran design significantly reduces swaying and spray foam, providing stable and quiet working condition for acoustic equipment
- Low noise electric Plug-in thruster, reduces signal-to-noise ratio by 20%

Autonomous Control with High Precision
- Radar, HD camera and AIS sensing enabling highly sensitive environmental perception
- Dual engine and dual propeller providing large torque, L25 can rotate in situ
- Able to navigate closely around constructions for zoom-in inspection
- Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm applied to minimize risk of collision

Auto Return
During a mission, if the L25 loses communication or is about to run out of power, it can automatically sail back to the designated location to avoid getting lost on the sea.
