[CA] [CA11] Location of Transducer on stern of boat

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Skamionek,

Please attach some photos of the transom of the boat taken from different angles, showing the location of the transducer relative to the bottom of the hull, to strakes or chine, to lowered drive units / outboards, and showing the hull features forward of the transducer. Please additionally understand that the RealVision and Sidevision are typically providing sonar coverage of a much wider area (port to starboard) than is supported by the RV transducer's high CHIRP conical sonar. Should the fish be located directly beneath the boat, then determine whether increasing to the Sonar channel's Gain settings improve marking of fish.
