The Lowrance 000-12568-001 Totalscan Skimmer Transom Mount Transducer 455/800 is an all-in-one transducer that matches proven CHIRP sonar with DownScan Imaging and StructureScan HD technology, making it possible to search for fish-holding structure and target fish with the same transducer. The Lowrance TotalScan transducer features multiple mounting options and is fully compatible with displays featuring integrated StructureScan HD, like Elite-5 Ti, Elite-7 Ti, Lowrancer HDS Gen3, Simrad NSS evo2, and NSO evo2 via the SonarHub Sounder Module. Note: When a TotalScan transducer is connected to a legacy display with a 7-pin blue connector, the side-scanning feature will not function.
