Si-Tex BT70L300-18 Bronze Thru-Hull CHIRP Transducer 300W 18° Tilt

The Si-Tex BT70L300-18 is a bronze thru-hull mount transducer designed for depth and temperature sensing in marine applications. This low-profile transducer features an 18-degree tilted element for optimal performance on deadrise hulls.

Key Features:

• CHIRP low frequency operation: 45-75 kHz for deep water penetration and target separation
• 300-watt power rating for enhanced performance
• Durable bronze housing ideal for saltwater environments
• 18-degree tilted element compensates for hull deadrise angles
• Integrated temperature sensor for accurate water temperature readings
• 26-foot cable with Echonautics connector included
• Low-profile design minimizes drag and turbulence

This thru-hull transducer provides reliable depth and temperature data for fishfinders and chartplotters. The bronze construction offers excellent corrosion resistance, making it suitable for both freshwater and saltwater installations. The CHIRP technology delivers superior target resolution and clarity compared to traditional single-frequency transducers.
