Echonautics BT87M1KW-18 Bronze Thru-Hull CHIRP Transducer 1kW 85-135kHz

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.
