AIRMAR Expands CHIRP Product Line With Release of Wide Beam Broadband Transducers

MILFORD, NH. (October 17, 2013) – AIRMAR Technology Corporation is pleased to
announce the expansion of the company’s award-winning CHIRP broadband transducers with the introduction of a new wide beam product line offering an expanded high frequency range of 150kHz to 250kHz. “The development of our new transducers is a direct result of feedback from our customers wanting all of the benefits of CHIRP products plus wider, high frequency beam angles,” stated Jennifer Matsis, vice president of sales and marketing. “In addition to expanded bandwidth, anglers using the new wide beam transducers will achieve more than twice the coverage under the boat compared to our current high frequency CHIRP transducers,” added Matsis. All 275LH-W series models will provide a low frequency option along with the new high frequency range of 150kHz to 250kHz.

A unique property of the new wide beam transducers is that the beam width is a
constant 25 degrees across the entire frequency band. Traditionally, high frequency transducers have narrow beam widths that change with frequency. Now, in addition to providing vast bottom coverage and improved fish detection in the upper water column, AIRMAR’s new wide beam format enables echosounders with advanced digital processing to produce crisper and larger return images on the fishfinder display. The new wide beam transducers are ideal for marking bait and game fish in shallow to mid water depths of 300 – 600 feet.


Since the company’s launch of CHIRP broadband transducers less than two years ago,
most major marine electronics manufacturers have incorporated CHIRP technology into their fishfinder product lines. In addition to providing the enabling technology for CHIRP-ready fishfinders, AIRMAR’s CHIRP broadband transducers enhance fish detection on virtually all of today’s fishfinders, including many non-CHIRP machines. With the ability to adjust frequency, an echosounder with advanced digital processing can operate AIRMAR’s broadband ceramics anywhere in the entire frequency band of 28 kHz – 250kHz. “CHIRP has completely revolutionized the way professional and sport fishing enthusiasts are using technology to find fish,” Matsis quoted. AIRMAR’s new wide beam CHIRP broadband transducers will be available in several mounting options to accommodate transom, pocket, tank and thru-hull installations.

    • Hi Calvin…at this time the M (in-hull) version of this transducer is not available. It is available in pocket-mount, thru-hull, transom-mount, and tank mount.

  1. Hi, the wide beam chirp announcement is fantastic. When will the thru hull versions be available and when manufacturers products will they be compatible with?

    Also, will there be separate transducers for low / high, or inclu
    ded in one unit?

  2. When will the wide beam CHIRP transducer be available and do you have an estimate cost? I am interested in a transom mounted unit for my aluminum fishing boat.

    • Hi Rich. Thanks for your message. The wide beam CHIRP transducers will be available in January 2014. The estimated cost is $2050.

    • Hi Steve. The B175H-W is a single element. The B175H-W is only available in the H version, as the H stands for High Frequency which is 150-250kHz. The standard B175H is 130-210kHz. I hope that answers your question.

    • With the Low frequency range you should see at least 1,000 feet with the 1kW B275LH-W (Low, High-Wide). We usually suggest that you could sound down to 2,500′ or more depending on conditions. The High frequency range for the wide beams seem to top out at around 600-700′.

  3. I am considering a Lowrance HDS 8 Gen2. The TM150M transducer is listed as an option. Will the new wide beam ones work with that unit?

    • Hi. You would also need SonarHub to use the TM150M. Yes, you could also use the new wide beam (B175H-W, 150-250kHz) with the Lowrance HDS 8 Gen 2 with SonarHub. However, you should check with Navico to see if they can read up to 250kHz. I am not sure if that has been confirmed yet.

  4. I rarely fish in water > 130 feet. What is the best Chirp transducer for a Garmin 741XS that will give me excellent bottom target distance of .05″? I am really interested in getting a unit that gives HD graphic displays of the bottom….and fish at, or near the bottom. I understand that Chirp touts target separation of .4″. This should be good enough to visually see fish on the bottom. Does such a unit – transducer combo exist yet?

    • Hi Mike. You’re in shallow water so we would suggest the B75H or B175H. If you want a wider beam then B175H-W. You may want to also speak with your marine electronics dealer.

  5. I have a hummingbird 597 CI HD DI COMBO FISHFINDER, 5 pin cable

    • Hi Earl. The transducers we make for Humminbird are for the 800, 900, and 1100 series only. You would need to use a Humminbird-made transducer for the 597. Thanks.

    • Hi Eddie…have you received all of the information on the new wide beam CHIRP transducers? Please let us know if you need more information.

  6. Hi

    I currently have furuno B164 thru-hull transducer….running off a Furuno GP 1870 F……please advise which wide beam broadband transducer would best suit

    Thanking you

    • Hi Mark. If you mean the standard wide beam, then SS264-200-Wide with 10 pin connector, or SS264 pair 50 and 200 if you want dual freq. (If Gemeco still have any in stock.) If not then you would need to go B175H-W and add a Furuno 10 pin connector.

    • Hello. This transducer is currently available. If you have trouble getting your hands on one, please let us know. Thanks!

    • Hi Manuel,
      Which wide beam model are you interested in? It is available to use with the Garmin GSD26.
      Depending on which model you want we can get you a part number.

  7. HI Jpiper,
    getting Raymarine chirp a78 with CP100 sonar downvision.
    looking first :A as an in hull if not ,B thru hull transducer :is this 275W good for this combination? if not, what second best?

  8. Hi,

    Which best fishifinder and their accessories can offer the best performance for the W-series transducer 275LH ?

  9. I am installing a Garmin GSD 26 CHIRP sounder and would like use a B-175H-W transducer. Is the B-175H-W compatible with the GSD 26?

  10. Hello I have a gp1870f , Is the b164 transducer compatible with because Im a bit confused choosing a transducer thanks

    • No. The TM150 is rated for 300 watts and those sounders are 600W. The TM150M is also Chirp Medium so neither of those sounders can operate within it’s frequency range. They are 50/200 sounders.
