Humminbird 710147-1 XP-9-20T In-Hull Puck Transducer Dual Beam 83/200kHz

The Humminbird XP-9-20T In-Hull Puck Transducer is a dual beam sonar transducer designed for installation inside single-layer fiberglass hulls. This hockey puck-style transducer eliminates the need to drill through your hull, making it ideal for trailered boats and maintaining hull integrity.

Key Features:

• Dual beam frequencies: 83 kHz (60° beam angle) and 200 kHz (20° beam angle) for versatile depth and detail
• In-hull puck design mounts inside single-layer fiberglass hulls using epoxy
• Built-in temperature sensor with probe on pigtail for accurate water temp readings
• 15-foot cable with 7-pin modular connector
• Compatible with HELIX series, Matrix series, PiranhaMAX series, and 100-1100 series fishfinders (non-CHIRP DI models excluded)
• No hull penetration required - preserves boat warranty and eliminates potential leak points

This transducer provides excellent performance for freshwater and inshore saltwater fishing applications. The dual beam configuration allows you to switch between wide coverage for locating fish and narrow beam for precise depth readings and detail. Installation requires cleaning the hull interior surface and bonding the transducer with marine epoxy.
