The 520-IHD (P-79) In-Hull "shoot through" style transducer is suitable for GRP boats.
Installation is very simple as there is no need to drill through hull holes. A unique wet-box with simple installation style allows for a deadrise offset of any angle between 0° and 22°.
The 600W dual frequency element (50 & 200kHz) is very sensitive holding bottom at high speeds. The transducer is supplied complete with wet box and pigtail for joining a speed temp sensor where all connections are hidden below deck.
