Find success on the water with an in-hull transducer

Garmin's GT8HW-IH 8-pin in-hull transducer makes it easier to find fishing spots thanks to high-wide CHIRP sonar that'll let you maintain depth accuracy, even when your craft is moving quickly. Got a fiberglass bass boat? Installing this transducer in the hull will help you avoid transom-mounted issues caused by cavitation bubbles. It boasts 250 watts of power so it can read down to 800 feet in freshwater. Pair it with select Garmin transom-mount transducers and an adapter cable so you can maintain depth at high speeds and scanning capabilities at trolling speeds.

Features

Overview: The Garmin GT8HW-IH is an in-hull mount sonar transducer. This 8-pin transducer has high-wide CHIRP traditional sonar (145-230kHz) and a 250-watt power rating. You can mount it in a flat section (less than 6° rise) inside a fiberglass hull to avoid cavitation issues common with transom-mounted transducers. It is an excellent way to maintain accurate depth readings in boats travelling at high speeds. With the optional Garmin Y-cable (010-12445-33), you can use the GT30-TM transom-mount transducer with the GT9HW-IH in-hull transducer to get depth readings at high speeds and scanning at trolling speeds. The GT8HW-IH has an attached 20' cable with a blue 8-pin connector, and an adhesive-backed foam in-hull fitting.

Specifications:

  • Frequency: CHIRP High Wide (145-230kHz)
  • Power: 250 watts
  • Beamwidth: 24° - 16°
  • Maximum Depth: 800 feet (freshwater)
  • Number of Pins: 8-pin
  • Supported Deadrise Angles: 0° to 6°
  • Dimensions: Diameter 2" Height 1.753"
  • Cable Length: 20 feet
  • Weight: 9.35 ounces

Customer Q&A

3 questions already asked

Q
Does this transducer have temperature and speed? And will it work on the vivid series?
jimmy  Apr 21, 2022
2 answers
A
No. This transducer is just sonar. Speed is tracked by the plotter itself by the built-in GPS antenna. Temperature requires a transducer that is physically touching the water. As for the Striker Vivid, that series uses 4 pin transducer connections. This transducer uses an 8 pin connection so it is not compatible. The Striker line only work with the transducers that they come with for the most part.

The In Hull GT8 does not have temperature or speed. The transom mount GT does have temperature. As for working on Vivid series, contact Garmin with your specific unit and they can let you know.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with system. They will be able to determine if this will integrate. If it does not, then they will also be able to discuss other options with you.
