As with every tilted-element transducer in the B175 family, the ceramic sensing element is fixed at the specified 20-degree angle inside the bronze housing so it points straight down at the water once mounted on a hull with matching deadrise, correcting for the steep transom angle typical of offshore centre-console and sportfishing boats without needing a separate external fairing block. High-Wide CHIRP transducers like this one are chosen by anglers who want the sharpest possible fish and structure detail in the depth ranges they normally fish, at the tradeoff of somewhat less maximum depth than a Low CHIRP variant would achieve — the right choice for inshore, nearshore reef and structure fishing rather than deep bluewater work.
