The GT8HW-IH sonar is ideal for small boats that want to install the sonar in the fiberglass hull rather than on the stern where it could interfere with the smooth flow of the water. It requires a flat part of the hull for mounting. It can maintain an accurate depth measurement even for boats traveling at high speed.
The 8-pin sonar is equipped with a traditional CHIRP broadband sonar (150-240 kHz) and has a rated power of 250 W. It can be used in combination with the GT30-TM sonar and adapter cable - in this case you have accurate depth measurement even at high speeds and scanning functions at normal fishing speeds.
Follow the enclosed installation instructions carefully to avoid damage to your boat.
