Airmar B75C-12-HW
Best high-resolution sonar for serious offshore sport fishing enthusiasts.
This thru-hull transducer turns your sonar into a high-definition window, offering the kind of target separation that makes finding baitfish effortless. You sacrifice the ease of a transom mount for a permanent, flush-fit installation, but the trade-off is unmatched clarity and bottom detection in deep water.
