This transducer is part of the Panoptix LiveScope System and requires the GLS 10 sonar black box to function. You get both LiveScopeTM Down and LiveScopeTM Forward modes in one transducer. It’s easy to adjust the transducer mode to fit your fishing techniques; use LiveScope Forward to see remarkably clear images of structure and swimming fish around your boat, and use LiveScope Down to see directly below your boat. The view automatically updates on your compatible Garmin chartplotter. Attitude Heading Reference System (AHRS) stabilization keeps your sonar view steady, even in rough conditions.
