The medium frequency delivers the right combination of coverage under the boat, extended depth range, and the ability to produce clean and accurate target and structure returns in mid to deeper water. Medium frequency also provides excellent shallow to mid-depth performance, bottom detail, and fish-target separation. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths down to 457 m (1500&#8242;) and gives ultra-clear target resolution.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-16214\" src=\"https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1-300x282.png\" alt=\"\" width=\"402\" height=\"378\" srcset=\"https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1-300x282.png 300w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1-327x308.png 327w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1-64x60.png 64w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1-96x90.png 96w, https:\/\/www.northsidemarine.com.au\/online-store\/wp-content\/uploads\/sites\/9\/2020\/05\/airmar-tm185m-3-1.png 623w\" sizes=\"auto, (max-width: 402px) 100vw, 402px\" \/><\/p>\n<h4 class=\"darkBlueColor\">Features<\/h4>\n<div class=\"row\">\n<div class=\"col-md-8\">\n<ul>\n<li>Depth and fast-response water-temperature sensor<\/li>\n<li>1 kW with a maximum depth of 457 m (1,500&#8242;)<\/li>\n<li>Medium frequency: 85 to 135 kHz\n<ul>\n<li>16\u00b0 to 11\u00b0 beamwidth<\/li>\n<\/ul>\n<\/li>\n<li>50 kHz of total bandwidth from one transducer<\/li>\n<li>Covers popular fishing frequencies of 88 and 107 kHz plus everything else in the bandwidth<\/li>\n<li>Medium frequency provides excellent shallow to mid-depth performance, bottom detail, and fish-target separation<\/li>\n<li>Transom-mount, urethane housing with a stainless steel bracket for installation on outboard and I\/O powered boats<\/li>\n<li>Also available as thru-hull (B285M,\u00a0B175M) and in-hull (M135M) models<\/li>\n<li>Exclusive\u00a0Xducer 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.
