See high-resolution images of fish swimming around structure and responding to your lure – as it happens – with new ActiveTarget™ Live Sonar. Featuring Forward, Down or Scouting views, ActiveTarget Live Sonar can scan fish locations and easily track their movements.

Perfect for pinpointing fish-holding areas like rockpiles, standing timber, weedbeds, ditches and drop-offs, Active Imaging™ 3-in-1 with Lowrance CHIRP, SideScan and DownScan delivers superior clarity, the best target separation and the highest resolution images of fish and structure at a longer range than any other structure imaging technology. Combine your HDS LIVE, Elite FS, or HDS Carbon with a Ghost Trolling Motor and an Active Imaging™ 3-in-1 Nosecone for picture-like views below, to the side, and the full 360 around your boat in unbeatable resolution.

Get the best of CHIRP sonar and DownScan Imaging™ on one screen with the exclusive FishReveal™ Smart Target view that helps you easily recognise fish from structure and cover on high-detailed DownScan images.
