Broadband / CHIRP Transducers
Technical Information
When Your Living Depends on Finding Fish...
Advantages of Thru-Hull Transducers
Rely on Airmar’s new broadband transducers for the ultimate fishing mission. Whether you’re a commercial
fisherman, charter captain, or tournament angler, there’s a new game in town! CHIRP transducers enable bottom
detection down to 3,000 m (10,000’) with 5 to 10 times greater detail and resolution so precise it’s possible to
distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to
115 kHz of total bandwidth in just one installation, saving customers time and money.
When thru-hull transducers are installed with a High-Performance Fairing, the transducer face is parallel to the waterline
resulting in a beam that is vertically oriented for maximum echo returns and the best possible performance. The fairing
compensates for hull deadrise and reduces turbulence over the transducer face, which allows tracking at speeds over 30
knots (35 MPH). This installation, when mounted in clean water (forward of propellers and running gear), produces the most
effective signal return since nothing on the vessel interferes with the transducer’s active surface. Thru-hull transducers will
work with any engine type: inboard, outboard, or I/O.
Airmar…it’s what’s under your boat.
Advantages of Tilted Element™ Transducers
The CHIRP Difference
Traditional marine fishfinders operate at discrete frequencies such as 50 kHz and 200 kHz, use relatively
short-duration transmit pulses, and use narrowband sonar transducers. In contrast, CHIRP (compressed
high-intensity radar pulse) uses a precise sweep pattern of many frequencies within a long-duration transmit pulse
from a broadband transducer, so the equivalent sound energy transmitted into the water is 10 to 1,000 times
greater than a conventional marine fishfinder. The echo energy returning to the transducer, superior to that
generated by a conventional transducer, is then processed by the fishfinder’s DSP (digital signal processing)
computer and displayed in ultra-sharp detail on the display. The combination of CHIRP, a broadband transducer,
and the fishfinder’s DSP, results in dramatically better fish and bottom detection, superior depth capability, and
significantly better performance at speed.
Does YOUR Fishfinder CHIRP?
Only CHIRP/Spread Spectrum sounders using Airmar broadband transducers can operate as a CHIRP fishfinder
system. When Airmar’s new transducer is paired with a broadband fishfinder, the result is 5 to 10 times greater
sensitivity and performance than current fishfinder technology. Packed with exclusive technology like
Transducer ID® and newly engineered piezoceramic elements, Airmar transducers are über sensitive and designed
to automatically sweep frequency bands from 28 kHz to 210 kHz with no tuning necessary. As a result, all targets
detected in the entire bandwidth will be seen on the display rather than only what is identified in traditional
frequencies at 50 kHz and 200 kHz.
Unique Transducer ID®
Airmar’s Transducer ID feature measures and stores the operating parameters for each transducer. This enables the fishfinder
to automatically configure itself to the transducer being used. The embedded microcontroller continuously monitors ceramic
operating temperatures inside the transducer, enabling closed loop control of power output. The transducer’s profile
can be presented on the display showing beamwidth coverage as a function of frequency. Stored data also assists with
troubleshooting, warranty or any required information about the transducer.
Quality “Q” Value
Q is a measure of bandwidth and the rise and fall times of target echoes. Airmar Q values range from 1.6 to 30, depending
on the model. Competitive transducers have an average Q of 25 to 30. The lower the “Q” number, the less ringing in the
transducer and the better the performance—improved individual fish separation along with bottom imaging in rapidly
changing water depths such as ledges and offshore canyons. All Airmar CHIRP transducers have a Q of 3 or less.

Tilted Element transducers are low-profile housings that protrude less than 6.35 mm (0.25”) outside of the hull. Rather than
using a high-performance fairing block to correct for the hull deadrise, the ceramic element is tilted inside the transducer at
either a fixed 12° or 20° angle, accommodating hull deadrise angles up to 24°. When installed to the hull, the tilted feature
provides built-in deadrise compensation, aiming the beam vertically which results in strong echo returns and accurate depth
readings. Tilted element transducers are an ideal solution for fast, trailered, sportfishing vessels where a thru-hull transducer
with a High-Performance Fairing cannot be installed.
Airmar’s complete line of twenty-four (24) CHIRP transducers are available in seven (7) different mounting options
to accommodate almost any hull design. CHIRP transducers are available at Gemeco Marine Accessories
www.gemeco.com and Airmar EMEA www.airmar.com/emea. Visit www.AIRMAR.com for a list of
CHIRP-ready transducers.
