Not content with simply looking forward, Garmin introduced Panoptix at the Miami International Boat Show. Its multidirection transducer covers the hemisphere around the boat in real time, looking forward, back, left and right. This is an adaptation of offshore commercial sonar, designed at the moment for inshore anglers. We think it's only a matter of time before offshore versions are available. LiveVu gives a near-live video moving image of the water ahead, showing fish swimming in and out of range or letting an angler track his lure back to the water. RealVu 3D Down paints a real-time image of the bottom structure below. The detail is astonishing.
