Garmin GT15M-IH CHIRP Transmitter - 600W Marine Echo Sounder

The Garmin GT15M-IH transmitter provides high-performance depth readings for boats that operate at high speeds. Designed for mounting directly in the plastic hull rather than on a rear mirror, this sensor helps prevent issues caused by cavitation. It supports a core cross-sectional angle of 0 to 25 degrees, ensuring reliable performance even in fast-moving water. This 8-pin transmitter utilizes 4 plastic tanks to support traditional CHIRP echo sounder functions within the mid-frequency range of 85 to 165 kHz. With a rated power of 600 W, it delivers the strength needed for accurate marine electronics performance. For expanded capabilities, this unit can be used with a GT30 TM transmitter and an adapter cable.
