In-hull transducers are mounted inside the boat’s hull without direct water contact. They are ideal for fiberglass boats and require little maintenance.
These transducers are attached inside the boat hull and use the hull material to send and receive sound waves. Since they don’t contact the water directly, they are protected from damage and fouling. They work best with fiberglass hulls but may be less effective on wooden or metal hulls due to signal interference. This makes them a low-maintenance option delivering stable and reliable readings, especially at lower speeds.
