This oscillator is part of the Panoptix Live Scope system. This oscillator needs to work with a GLS 10 sonar black box. You can use both LiveScope ™ Down mode and LiveScope ™ Forward mode with a single oscillator. You can easily adjust the oscillator mode according to your fishing technique. With LiveScope Forward, you can see the underwater conditions around the ship and the swimming fish in amazingly clear images. You can also use LiveScope Down to see what's going on underwater just below the ship. The corresponding Garmin chart plotter will automatically update the image. The Attitude and Heading Reference (AHRS) remains stable, so you can get stable sonar images even in situations with large vibrations.
