Si-Tex BT70MA600-18 Bronze Low-Profile Thru-Hull CHIRP Transducer 600W 80-130kHz 18° Tilt

The Si-Tex BT70MA600-18 is a bronze low-profile thru-hull medium-frequency CHIRP transducer designed for professional marine applications. This 600-watt transducer features an 18° tilted element that matches vessels with 16° to 20° hull deadrise angles, minimizing drag and optimizing performance at high speeds.

Key Features:

• CHIRP frequency range: 80-130 kHz for medium-frequency operation
• RMS power output: 600 watts
• Beamwidth: 24° to 17° at 3dB
• Maximum depth capability: 900 feet
• Built-in NTC temperature sensor
• 26-foot cable length with 8-pin connector
• Urethane acoustic window for optimal signal transmission
• Hole diameter: 2.38 inches for installation

This low-profile thru-hull design matches the vessel's deadrise to a specific angle, ensuring proper transducer alignment for accurate depth readings and superior fish-finding performance. The bronze construction provides excellent durability in saltwater environments, while the medium CHIRP frequency range offers an ideal balance between depth penetration and target resolution for most fishing and navigation applications.
