Product Details

The Si-Tex BT87M1KW-18 is a premium bronze thru-hull CHIRP transducer designed for accurate depth and temperature readings in saltwater environments. This low-profile transducer features an 18-degree tilted element for optimal performance on vessels with deadrise angles, ensuring maximum signal transmission even when installed on angled hulls.

Key Features:

  • 1 kilowatt power output for deep-water performance and excellent target separation
  • 85-135 kHz medium frequency CHIRP technology for superior clarity and detail
  • Bronze housing construction for durability and corrosion resistance in marine environments
  • 18-degree tilted element compensates for hull deadrise angles
  • Low-profile design minimizes drag and hydrodynamic impact
  • Integrated temperature sensor for accurate water temperature readings
  • 26-foot cable with Echonautics connector for reliable connectivity
  • Compact dimensions: 4.8" diameter x 5.2" height
  • Requires 3.45" diameter hole for installation

This thru-hull transducer is ideal for serious anglers and boaters who demand professional-grade sonar performance. The CHIRP technology provides significantly better fish detection and bottom definition compared to traditional single-frequency transducers, while the bronze construction ensures long-term reliability in saltwater conditions.
