The best performance on vessels 25 feet and up becausethe transducer face is in “clean” water below theboundary layer (bubbles running down the hull) The fairing compensates for hull deadrise and reducesturbulence over the transducer face, which allowstracking at speeds over 30 knots (35 MPH) When mounted in clean water (forward of propellersand running gear), thru-hulls produce the most effectivesignal return since nothing on the vessel interferes withthe transducer’s active surface

Why does frequency matter?High Frequency Greater Detail (ex. 130-210 kHz)Selecting the best frequency for your specific applicationis very important. The good news is that once you knowwhat frequency will work best for the type of fishing youdo, there’s an AIRMAR transducer designed to maximize theperformance of your sounder. More sensitive to small targets and will send back detailedinformation which will display as crisp, high-resolutionimages on the echosounder screen Best for shallower water and popular with anglers fishingat depths less than 1500 feetAIRMAR Chirp transducers are available in various frequencyc ombinations: Dual Band: Single Band:ūū Low/High (LH)ūū Lowūū Low/Medium (LM)ūū Mediumūū Low/High Wide (LHW)ūū Highūū Low Wide/Medium (LWM)ūū High WideMedium Frequency The Best of Both Worlds(ex. 80-130 kHz) Provides the ability to sound deeper than the highfrequency, along with better resolution than thelow frequency Wider beam than the high frequency, achieving morecoverage under the boat and greater opportunity to find fish Clear images at higher boat speedsLow Frequency Greater Depth (ex. 42-65 kHz) Sound waves will not present as clear a picture of thebottom on the display, but will sound down in very deepareas where high frequency sound waves cannot reach Provides greater depth range, wider beamwidth, andultimately more coverage under the boat Chirp signal processing technology used with AIRMARbroadband, Chirp-ready transducers provides more detailat greater depths and is less susceptible to noise Great for operating at high boat speeds1 kWMax depth 3000'0'2 kWMax depth 6000'HIGHWIDEHIGHWIDEHIGHMED2-3 kWMax depth 6000'LOW8000'LOW10000'

The Chirp AdvantageTraditional sounders operate at only two discrete frequencies – typically 50 kHz and 200 kHz. This resultsin limited depth range, resolution, and ultimately whattargets can be detected in the water column.In contrast, AIRMAR’s game-changing Chirp-ready transducers provide over 70 kHz of bandwidth. Transmitting over a wide frequency band results in agreater opportunity to detect what is in the water column.As a result, all targets detected in the entire bandwidth willbe seen on the display–even those fish holding close tothe bottom–ultimately improving target detection, detail,and range resolution.Most Chirp transducers vary their beam width as theysweep through their frequency range (low, medium, andhigh). At the lowest frequency the beam is the widest andit narrows as the frequency increases.The fish must be in the beam to be represented on the display.AIRMAR’s new wide beam Chirp transducers are the exception to this rule and have a fixed beam width ofeither 25 or 40 across the frequency band. This translatesinto even more coverage under the boat, revealing morefish in the water column than ever before.Courtesy of NavicoCourtesy of HumminbirdAdditional Mounting OptionsTank MountIn-HullPocket Mount Keel MountChoosing your mounting option depends on the design ofthe hull as well as the material it’s manufactured with, theboats intended use, and the desired level of performance.Courtesy of GarminCourtesy of RaymarineNeed Help Choosing the Right Transducer?Download the free, award-winning iNstall app!
