Garmin GT15M-IH GT15M-IH, Black, One Size, 0753759148577

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.
