What is a Furuno Transducer?
A Furuno transducer is a sophisticated device that converts electrical signals into sound waves and vice versa, enabling users to gather critical data about the underwater environment. These sound waves, emitted in a cone-shaped beam, travel through the water, bounce off objects like the seafloor, fish, or structures, and return to the transducer. By calculating the time it takes for the waves to return, the transducer determines the distance and composition of underwater objects, providing real-time insights into depth, fish location, and bottom structure.
Furuno, a leader in marine electronics for over 80 years, designs transducers that excel in performance, reliability, and versatility. Their transducers are integral to fish finders and chartplotters, such as the Furuno FCV-800 and TZT3 series, delivering high-resolution data for navigation and fishing applications.
How Transducers Work
Transducers operate using sonar technology. The device emits sound waves at specific frequencies, which vary depending on the model and application. Higher frequencies (e.g., 200 kHz) provide detailed images in shallow waters, ideal for bottom fishing, while lower frequencies (e.g., 50 kHz) penetrate deeper waters, suited for offshore fishing. Furuno’s transducers often incorporate advanced features like CHIRP (Compressed High-Intensity Radiated Pulse) technology and bottom discrimination, which enhance image clarity and target separation.
Key Features of Furuno Transducers
Furuno transducers stand out due to their innovative design and robust functionality. Below are the primary features that set them apart:
