Airmar In-Hull Tank

The Airmar In-Hull Tank is a purpose-built transducer housing designed for anglers and boaters who demand reliable sonar performance without the complications of through-hull installation. This specialized tank fits directly into the boat's hull cavity, allowing you to run 2KW or 3KW Airmar transducers while maintaining the clean, integrated appearance serious fishermen prefer. Whether you're targeting structure in shallow lakes or precision-marking offshore contours, an in-hull installation eliminates drilling concerns and keeps your hull integrity intact.

The tank's engineering centers on deadrise angle compensation—the hull's critical V-shape is replicated in the tank's cut geometry to ensure proper transducer orientation and optimal acoustic projection. This design detail is what separates adequate sonar from genuinely useful fish-finding clarity. The tank couples with compatible Airmar transducer models (R199, R299, R399, R111, R599C) and leverages Airmar's marine-grade construction to withstand saltwater exposure, temperature fluctuation, and the vibration that comes with extended time on the water. The 1 lb weight minimizes added burden to your hull while maintaining the structural stability needed for consistent signal transmission.

Tournament anglers, coastal fishermen, and recreational boaters running Airmar 2KW or 3KW systems benefit most from in-hull tank installation—particularly those with finished cabin interiors or composite hulls where drilling poses risk. Installation requires confirmation of your transducer model compatibility and proper tank positioning within the hull cavity to maintain the deadrise angle correction. This solution works best in boats with existing mounting provisions or where hull modification is undesirable, delivering the sonar reliability serious anglers need without compromising vessel structural integrity.
