World’s smallest multibeam sonar The Gemini 720im fuses Tritech’s Gemini multibeam technology with Tritech’s Micron technology to create the world’s smallest multibeam imaging sonar. Having a 90° horizontal field of view and 50m range, with an update rate up to 20Hz, the Gemini 720im brings real-time imaging to places where multibeam was never possible before. With incredibly compact dimensions the Gemini 720im can be used in applications where size is critical. This makes the Gemini 720im ideally suited for micro ROV/AUVs in addition to applications where space is restricted or weight is critical, including diver helmet and pole mounted applications such as Search and Recovery (SAR) operations Benefits Lightweight and compact 90° horizontal field of view Ethernet and serial communications Serial Auxiliary port Low power Features 20Hz update rate 300m depth rated Windows & Linux Software Development Kit (SDK) CHIRP & CW processing Mounting kits supporting 10deg downward tilt Applications Micro ROV/AUV navigation Obstacle avoidance Diver operations Aquaculture monitoring Vessel/Pole mount target search Compatibility Chasing M2 Pro M2 Pro Max Specifications Acoustic Specifications Operating frequency: 720kHz Angular resolution: 2.34° acoustic, 0.7° effective Range: 0.2m to 50m Number of beams: 128 Horizontal beam width: 90° Vertical beam width: 20° (±10° about horizontal axis) Update rate (typical operation): 3 to 20Hz (range dependent) Range resolution: 8mm Mode of operation: CW or CHIRP Speed of Sound: Adaptive beamforming based on user specified speed of sound Interface Supply voltage 12 to 48V DC Power requirement 4.5W – 17W (7.5W average) Main port protocol Ethernet (100Base-T) and/or Serial (RS232 or RS485) Auxiliary port protocol Serial (RS232 or RS485) Connector type Main: Seacon HUML-12, Impulse MKS(W)-3L10 & Tritech MicronAux: Tritech Micron Physical specification Depth rating 300m Weight in air 0.435kg Weight in water 0.244kg Temperature rating -10 to +35°C (operating), -20 to +50°C (storage)
