With one Panoptix Forward transducer, you can actually see the bottom, structure and fish swimming around in front of your boat ? in real time; even while stationary. You get 2 impressive views: LiveVu Forward and RealVu 3-D Forward. LiveVu Forward updates the entire view with a single ping and has a more “live video” look, providing real-time moving sonar images. You can see fish swimming toward or away from the boat. You can see small baitfish and large target fish swimming around, even your lure as you reel it in. RealVu 3-D Forward updates a slice of the 3-D volume with each ping and take 1 to 4 seconds to update the entire volume. It shows the bottom and fish in the water column coming toward the boat. It sweeps forward, and the history on screen is only one sweep. The forward-facing transom transducer should be mounted in a location that is out of the water at speeds over 32 km/h (20 mph). If located below the water line, cruising speeds over 40 km/h (25mph) should be avoided. The transducer can generate strain and water spray at higher speeds and can cause the transducer element to rotate in the mount. Mount the transducer to a secure (robust) area of the boat. Consider the placement to avoid damage to boat. If you have any doubts, contact a professional marine installer.
