How a Transducer Works What is a Transducer? A good shnder depends on an efcient transducer to send and receive signals. The transducer is the heart of an echosounder system. It is the device that changes electrical pulses into sound waves or acoustic energy and back again. In other words, it is the device that sends out the sound waves and then receives the echoes, so the echosounder can interpret or “detect” what is below the surface of the water. How Does a Transducer Know How Deep the Water is? The echosounder measures the time between transmitting the sound and receiving its echo....

Selecting Frequencies Can Fish Hear the Sound Waves Produced by a Transducer? Sound waves are ultrasonic. Most sh are unable to hear frequencies higher than about 500 Hz to 1 kHz. The ultrasonic sound waves sent out by Airmar transducers have frequencies ranging from 10 kHz to 2 MHz (10,000 Hz to 2,000,000 Hz), clearly beyond the hearing of sh. They are also above (ultra) the sound (sonic) that human ears are able to hear. Humans can hear sound waves from 10 Hz to 20 kHz. However, most people can hear the transmit pulses of our 10 kHz transducers; they sound like a series of clicks....

Transducer Styles, Mounting & Installation Tips Transducer Mounting Styles Transducers are typically mounted in one of three ways: through the hull, inside the hull, or on the transom. Thru-Hull—Through the Hull The transducers in this mounting style fall into two categories. There are “ush” thru-hull sensors that sit ush or nearly ush with the boat hull. They are recommended for smaller boats with a minimum deadrise angle. And they are often installed on sailing vessels, because they produce minimal drag. External thru-hull transducers extend beyond the hull’s surface and usually require a...

Transducer Styles & Mounting Methods Application or Expectation for the Transducer Cruising and Sailing If time on the water is spent sailing or cruising, a high-power transducer is not needed. Single-frequency 200 kHz transducers or a 235 kHz Smart™ Sensor is adequate. Accurate depth readings will be achieved up to 152 m (500’) depending on the depth instrument. Commercial Fishing These transducers are available in frequencies from 24 kHz to 210 kHz and power from 1 kW to 4 kW. Units feature high-efciency designs, producing superior shnding and clear and distinct images of both the bottom...

Advantages of High-Performance Fairings Without High-Performance Fairing With High-Performance Fairing High-Performance Fairing Achieve maximum shnder performance by installing an Airmar transducer with a High-Performance Fairing. Each High-Performance Fairing is custom designed to match its transducer model. The fairing assures a vertical beam which results in strong return echoes. Additionally, the streamlined shape reduces drag and minimizes turbulence over the face of the transducer. At speeds above 30 knots (34 MPH), screens continue to display clear images and solid bottom tracking....

TM270W Wide-Beam Performance on Y our Transom The SS270W, 1 kW, twin, wide-beam is now available as a transom-mount for larger trailered boats with outboards and I/O’s. The TM270W’s high-performance mounting bracket is easy-to-install and has a streamlined shape that delivers high-speed performance up to 30 knots (35 MPH). See the Wider Picture The TM270W gives you four times the beamwidth at 200 kHz than other high-performance transducers. Since the width of the beams are the same at both frequencies, a split-screen shnder display will clearly show the same water column and bottom...

TM260 Powerful, Y et Sensitive! The new TM260 takes the legendary performance of the B260 to your vessel’s transom. This top-of-the-line broadband transom-mount brings crystal clear imaging to any of today’s shnders. The large 200 kHz element and the seven-element 50 kHz array are excellent for bait and game sh separation along with detecting ground sh holding tight to the bottom. The TM260’s high-performance mounting bracket is easy-to-install and has a streamlined shape that delivers high-speed performance up to 30 knots (35 MPH).
