I have had the Garmin PanOptix system in the rear of my boat now for 2 years. I see things on it that I don’t see on my Lowrance HDS/ Airmar sonar system AND vice versa. ( very inconvenient to have customers ask “ if those are fish right now in your riggers, why aren’t we catching them “) ANYWAY: given I have the PanOptix + Lowrance HDS/ Airmar system facing essentially backwards what theoretical benefit is forward facing sonar for a trolling boat. Thanks for any experienced comments
