320N Fleet Echosounder

The 320N Echosounder is a sophisticated digital ‘Next Generation Fathometer’ (NGF). This marine navigation echosounder has an LED backlit LCD colour display with touchscreen interface for control and real-time data display including internal data storage of full-resolution echogram image data for post acquisition review and hardcopy output of nautical charts. The echosounder control software employs smart algorithms to allow hands-free operation with manual override capability for performance optimization in extreme conditions.

The 320N Navigation Echosounder with shock approved mounting fixture provides an impressive Grade A Shock Certification. The 320N’s compatibility with existing UQN-4 foundation, combined with recent US Navy UQN-10 designation, make it a logical and efficient drop-in replacement the legacy UQN-4(4A) Fathometer. The addition of a Remote Display and sonar signal simulator (EchoSim) rounds out your fleet navigation package.
