UAC-FLS200D 
Dual-Frequency  Multibeam Forward Looking Sonar 

Shallow & Turbid Water Ready | 500m Ultra-Range

200kHz / 425kHz Imaging Sonar for ROV, AUV & USV

Detect Suspended Underwater Targets at Extreme Range While Capturing High-Definition Acoustic Imagery for Identification

The UAC-FLS200D dual-frequency forward-looking sonar adopts real-time dual-frequency multi-beam imaging technology. It can simultaneously realize long-range detection and high-definition imaging recognition of suspended targets in the water ahead of the sonar. With an embedded processor, the unit features high integration and low power consumption, suitable for operations requiring both long-range detection and target identification.
