Echonautics

<h3>About Echonautics</h3><p>Echonautics is a marine electronics brand built on a singular mission: to push the boundaries of underwater sonar technology. Born from a powerful collaboration between an American leader in transducer research and design and a well-established Italian marine electronics manufacturer, Echonautics represents a true meeting of minds — and continents. The result is a lineup of <strong>sonar and CHIRP transducers</strong> that combine cutting-edge American engineering with decades of precision Italian craftsmanship.</p><h3>A Legacy of Expertise</h3><p>With a combined heritage spanning over 45 years in high-quality transducer manufacturing, Echonautics brings a depth of knowledge to the marine industry that few brands can match. Every product in the Echonautics lineup is meticulously <strong>designed in the USA</strong> and <strong>crafted in Italy</strong>, ensuring each unit meets rigorous international quality standards. This dual-continent development process is not just a marketing point — it reflects a genuine commitment to engineering excellence at every stage of production.</p><h3>CHIRP Transducer Technology</h3><p>Echonautics has built a strong reputation as a premier <strong>CHIRP transducer</strong> manufacturer. CHIRP (Compressed High-Intensity Radiated Pulse) technology delivers significantly greater target separation, depth penetration, and resolution compared to traditional single-frequency sonar. For anglers, navigators, and marine professionals who demand the clearest possible picture of what lies beneath the surface, CHIRP transducers represent the modern standard — and Echonautics engineers theirs to perform at the highest level.</p><h3>Sonar Transducers Built for the Marine Environment</h3><p>Beyond CHIRP, Echonautics offers a range of <strong>sonar transducers</strong> engineered for durability and precision in demanding marine conditions. Whether you need through-hull mounting, transom-mount solutions, or custom configurations, Echonautics approaches each design with the same attention to compliance with international best practices. Their custom-made sonar transducer capabilities make them a go-to resource for specialized installations where off-the-shelf solutions simply won&apos;t do.</p><h3>Custom Solutions and Air Sensors</h3><p>One of Echonautics&apos; most distinctive offerings is their ability to produce <strong>custom-made sonar transducers</strong> tailored to specific vessel types, frequency requirements, or integration needs. This flexibility, combined with their line of <strong>air sensors</strong>, speaks to the brand&apos;s broader commitment to precision sensing technology across the marine environment. For OEM partners or individual boaters with unique requirements, Echonautics&apos; custom capabilities set them apart from mass-market competitors.</p><h3>Why Choose Echonautics?</h3><ul style="list-style:disc"><li>Designed in the USA, manufactured in Italy to international quality standards</li><li>Over 45 years of combined expertise in transducer research and production</li><li>Specialization in both CHIRP and traditional sonar transducer technologies</li><li>Custom transducer manufacturing for specialized and OEM applications</li><li>Comprehensive product range including air sensors and marine sonar solutions</li></ul><p>Whether you are outfitting a fishing boat, a commercial vessel, or a custom marine build, Echonautics delivers the kind of precision sonar technology that serious mariners trust.</p>

Product Details

The Echonautics BT87M1KW-18 is a bronze low-profile thru-hull transducer designed for medium-frequency CHIRP sonar applications. This 1kW transducer delivers exceptional underwater imaging with a frequency range of 85-135kHz, making it ideal for deep water fishing and bottom mapping in saltwater environments.

Key Features:

  • Medium-frequency CHIRP technology for superior target separation and clarity
  • 1kW power output for deeper penetration and better signal-to-noise ratio
  • Bronze housing provides excellent corrosion resistance in saltwater applications
  • Low-profile design minimizes drag and turbulence
  • 18° deadrise angle tilt for optimal mounting on various hull types
  • Thru-hull installation for clean, permanent mounting below the waterline
  • 85-135kHz frequency range optimized for depths up to 3,000 feet

Technical Specifications:

  • Frequency Range: 85-135kHz
  • Power: 1kW (1000 watts)
  • Mounting Style: Thru-Hull
  • Housing Material: Bronze
  • Deadrise Angle: 18°
  • CHIRP Type: Medium-Frequency

This transducer is compatible with CHIRP-enabled fishfinders and chartplotters that support medium-frequency operation. The bronze construction makes it particularly well-suited for saltwater vessels including sportfishing boats, cruisers, and offshore vessels.

Got them fast. Easy install and my boat rolls on and off so east now. Also installed a Drotto auto lock.
