Humminbird® High Definition Side Imaging® Sonar

Side Imaging® Sonar, with its amazingly clear, picture-like images of fish, the bottom and structure, is available exclusively in select 1100, 900, 800 and 700 Series™ fishfinders. It’s the ultimate structure-finding tool, and with its massive coverage (150 metres from side to side!) you can scan in mere minutes what used to take hours.

Features:
• Mark the GPS location of promising structure directly on screen
• Magnify the detail with multiple zoom levels
• High frequency sonar (not a camera) cuts through murk with crystal clarity
• Up to 146 metres of coverage from side to side, scans huge areas fast
• Units with Side Imaging® also include traditional down looking 2D” sonar

Understanding the screen

(A)
Boat location: The position of your boat in relation to the on-screen image. The on-screen image is a history of what you have passed over.		 (B)
Water column: The dark blue area shows structure and activity between the surface and bottom directly under the path of your boat.		 (C)
Bottom profile: Reveals depth and attitude of the bottom directly beneath the path of your boat.		 (D)
Flat terrain: Neutral shades of blue represent flatter terrain.		 (E)
Descending terrain: Dark shades of blue represent descending terrain.
(F)
Rising terrain: Lighter shades of blue typically represent terrain rising from the bottom. Sometimes, very hard bottoms appear as a
whiter shade.		 (G)
Fallen log with shadow: The shortened horizontal shadows indicate structure very close to the bottom of the lake. The angle of the shadow gives away the orientation of the log.		 (H)
Standing timber with shadow: Objects standing off the bottom typically appear as a bright spot, or a clearly defined bright shape with an adjacent, dark sonar "shadow." This shadow is not caused by light rather it's the lack of sonar return because the object has already reflected the sonar energy. Generally, long shadows indicate the object is tall, and small shadows indicate something short. It's important to note the shadow will often tell you more about the object than the primary sonar reflection.

Understanding the beam

Humminbird® Side Imaging® Sonar uses a razor thin beam to take a "sonar snapshot" of the area up to 240 ft. to the left and right of your location. The return image for this slice is then added to the images for this slice is then added to the images taken immediately before and after to build an incredibly detailed view of the lake bottom.
