The B75 and SS75 are low-profile, through-hull, single band CHIRP transducers. They are available in the High band, Medium band or Low band
and in three levels of tilt (0°, 12° and 20°) to compensate for hull deadrise. The B75 and SS75 contain one single ceramic assembly, and a fast-response water temperature sensor.
The Low band covers the popular 50 kHz frequency for deeper water, the Medium band covers the popular 88 kHz and 107 kHz frequencies for lake fishing, and the High band covers the popular 200 kHz frequency for salt-water fishing.
The B75 has a bronze housing and the SS75 has a stainless steel housing. They are otherwise identical.
