## Overview

The Garmin GT15M-IH is a high-performance marine transmitter designed for fiberglass hull installation, delivering accurate depth readings at high speeds with a powerful 600W CHIRP echo sounder operating in the 85-165 kHz range. Its plastic hull mount prevents cavitation interference, ensuring reliable underwater data for serious boaters and anglers. Compatible with GT30 TM transmitters and adapter cables, it offers versatile echo sounder functionality for enhanced marine navigation.

## Description

Product Description The GT15M-IH transmitter is ideal for boats where the transmitter is to be mounted in the plastic hull and not on the rear mirror where there may be a compromise due to cavitation. It supports a core cross-sectional angle of 0 to 25 degrees and is excellent for boats that ride at high speed while still maintaining accurate depth readings. The 8 pin transmitter with 4 plastic tanks supports traditional CHIRP echo sounder functions in the mid-frequency range (85 to 165 kHz) and has a rated power of 600 W. It can be used together with a GT30 TM transmitter and an adapter cable, so you can continue to get depth readings at high speeds and continue to use echo sounder functions at speeds for trolling.

Review: チャープ発振でヤリイカが群れでいれば反応します。 - 今までは振動子を上げ下ろしして使用、不便なのでインナーハルへ変更。 GT-51振動子で映ったヤリイカがこのGT-15振動子、それもインナーハルで映るか心配でした。 多少の違いはありますが問題なく使用できました。
