The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25\u00b0 beam for all frequencies which results in superior resolution. The constantly wide beam provides twice the coverage and clear fish arches on the display compared to most high-frequency, narrow-beam transducers.<\/p>\n<p class=\"TypographyStyle-sc-11lquxl gVBKsR\">The high wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage are essential down to 152 m (500&#8242;). The low-frequency band and 1 kW of power also support great deep-water performance. Get the best of both worlds with Airmar\u2019s Chirp-ready transducer with wide-beam coverage.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-16222\" src=\"https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1-300x265.png\" alt=\"\" width=\"475\" height=\"420\" srcset=\"https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1-300x265.png 300w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1-327x289.png 327w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1-68x60.png 68w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1-102x90.png 102w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2019\/04\/airmar-tm275lhw-1.png 602w\" sizes=\"auto, (max-width: 475px) 100vw, 475px\" \/><\/p>\n<h4>Features:<\/h4>\n<ul class=\"UnorderedList-sc-1gl7lfr iMchvn\">\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Depth and fast-response water-temperature sensing<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">1 kW of power for great deep-water performance from the low frequency<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Low frequency: 42 to 65\u00a0kHz\n<ul class=\"UnorderedList-sc-1gl7lfr iMchvn\">\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">25\u00b0 to 16\u00b0 beamwidth<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Maximum depth of 914\u00a0m (3000&#8242;)<\/li>\n<\/ul>\n<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">High frequency: 150 to 250\u00a0kHz\n<ul class=\"UnorderedList-sc-1gl7lfr iMchvn\">\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">25\u00b0 constant beamwidth<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Maximum depth of 152\u00a0m (500&#8242;)<\/li>\n<\/ul>\n<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">123 kHz of total bandwidth from one transducer<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Covers popular fishing frequencies of 50 and 200\u00a0kHz plus everything else in the bandwidth<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">High frequency delivers superior shallow-water performance, bottom detail, and fish-target separation<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">High wide beamwidth yields more coverage for detecting fish in the upper-water column<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Stainless steel, kick-up bracket locks in the \u201cup\u201d position and will not damage the transom<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">SEALCAST<sup>\u2122<\/sup>, seamless, urethane housing for long life in the water<\/li>\n<li class=\"ListItem-sc-1ki5k3p gSKIUI\">Also available as thru-hull (B275LHW) and pocket (PM275LHW) mounts Patented Xducer ID<sup>\u00ae<\/sup>\u00a0technology<\/li>\n<\/ul>\n<h4>The Benefits of AIRMAR\u2019s Chirp-ready Transducers<\/h4>\n<p>\u2022 One broadband transducer covers up to 117 kHz of bandwidth \u2013 greater opportunities to detect fish in the water column<br \/>\n\u2022 Superior resolution \u2013 precise separation between baitfish and gamefish represented on the display with crisp images<br \/>\n\u2022 Enhanced bottom fishing \u2013 resolve targets close to the bottom or near structures\/wrecks<br \/>\n\u2022 Amazing detail \u2013 recognize haloclines and thermoclines<br \/>\n\u2022 Improved signal-to-noise ratio \u2013 find fish and track bottom at high boat speeds<\/p>\n<h4>Benefits of Transom Mount Transducers<\/h4>\n<p>Transom models are best suited for small and trailered vessels where a thru-hull installation is not practical. Perfect for freshwater boat styles and centre consoles. Simple to install and ideal for small trailered vessels where a thru-hull may interfere with loading.<br \/>\n\u2022 Simple installation on the transom of the boat<br \/>\n\u2022 Great performance at boat speeds below 30 knots<br \/>\n\u2022 Easy maintenance and low-cost replacement<\/p>\n<h4>Why does Frequency Matter?<\/h4>\n<p>Selecting the best frequency for your specific application is very important. The good news is that once you know what frequency will work best for the type of fishing you do, there\u2019s an AIRMAR transducer designed to maximize the performance of your sounder.<br \/>\nAIRMAR Chirp transducers are available in various frequency combinations:<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"301\">Dual Band:<\/p>\n<ul>\n<li>Low\/High (LH)<\/li>\n<li>Low\/Medium (LM)<\/li>\n<li>Low\/High Wide (LHW)<\/li>\n<li>Low Wide\/Medium (LWM)<\/li>\n<\/ul>\n<\/td>\n<td width=\"301\">Single Band:<\/p>\n<ul>\n<li>Low<\/li>\n<li>Medium<\/li>\n<li>High<\/li>\n<li>HighWide<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Low Frequency = Greater Depth (ex. 42-65 kHz)<\/p>\n<p>\u2022 Sound waves will not present as clear a picture of the bottom on the display but will sound down in very deep areas where high-frequency sound waves cannot reach<br \/>\n\u2022 Provides greater depth range, wider beamwidth, and ultimately more coverage under the boat<br \/>\n\u2022 Chirp signal processing technology used with AIRMAR broadband, Chirp-ready transducers provide more detail at greater depths and are less susceptible to noise<br \/>\n\u2022 Great for operating at high boat speeds<\/p>\n<p>High Frequency = Greater Detail (ex. 130-210 kHz)<br \/>\n\u2022 More sensitive to small targets and will send back detailed information which will display as crisp, high-resolution images on the echosounder screen<br \/>\n\u2022 Best for shallower water and is popular with anglers fishing at depths less than 1500 feet<\/p>\n<p>Medium Frequency = The Best of Both Worlds (ex. 80-130 kHz)<br \/>\n\u2022 Provides the ability to sound deeper than the high frequency, along with better resolution than the low frequency<br \/>\n\u2022 Wider beam than the high frequency, achieving more coverage under the boat and greater opportunity to find fish<br \/>\n\u2022 Clear images at higher boat speeds<\/p>\n<h4><span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2023\/07\/Airmar-TM185M-Brochure-Transom-Mount-Chirp.pdf\">Brochure<\/a><\/span><\/h4>\n<p><iframe loading=\"lazy\" title=\"Transducer University - Transducer Location\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/MFsKbpAKzUU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><span style=\"line-height: 1.3em\"><u><b>\u00a0<\/b><\/u><\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"TypographyStyle-sc-11lquxl gVBKsR\">Get more coverage under your boat with Airmar\u2019s unique wide-beam, low and high-frequency, Chirp-ready Airmar TM275LHW.
