Double ultrasonic transducer BBUA-F50K200K-B

immersible

Overview
The BBUA-F50K200K-B is a dual-frequency fish-finding transducer combining 50 kHz and 200 kHz channels in a single housing. It is designed for fisheries acoustics, marine depth sounding and underwater target search. The documented recommended operating range for the 200 kHz channel is 0.6 to 120 m.

Applications

• Fish detection and fisheries-acoustics systems
• Marine depth sounding
• Underwater target search
• Integration into fisheries-acoustics equipment and vessels
