Revolutionary 360 Imaging scans underwater places that are virtually impossible to see with conventional sonar. It produces a 150-ft. beam that sweeps in every direction to create a 300-ft. circle of detection around your boat, letting you see fish all around you without moving over them (1.6 acres of total coverage). The imaging beam sweeps the surrounding water and detects fish, underwater structure, rocks, terrain changes and more - helping you target fish hideouts with surgical precision that would remain hidden to other sonar devices. Four beam speeds and adjustable 10°-360° sweep areas let you fine tune the system and isolate specific areas for maximum detail or faster returns. The lower beam speeds scan slower and more thoroughly to produce better-quality images, while the higher beam speeds deliver faster refresh rates. The adjustable sweep area lets you adjust the beam sweep between 10°-360° in any direction, or choose one of four preset sweep settings that scan fore, aft, port or starboard with a 180° arc. Mark important returns with a waypoint and keep track of productive fishing spots with the GPS on your Humminbird unit (select units only). Split-screen views also let you see 360° imaging with SwitchFire™ sonar or GPS cartography. Adjustable beam sensitivity for adapting to varying water conditions. Choose from eight colour palettes for easy viewing. Adjustable image sharpness for clearer resolution in different light conditions. The 360 Imaging Transducer Deployment System silently lowers the transducer below the hull and prop for unobstructed views at every angle. The transducer can be deployed with easy-to-use buttons on the Transducer Deployment System housing or by using the controls on your Humminbird fish-finder unit - and it's adjustable to prevent grounding andallows you to fish shallower depths. Requires an Ethernet-ready, Side Imaging®-equipped Humminbird fish finder (sold separately). Older side-imaging units will need a software update.
