High Definition Side Imaging Sonar

(1197c SI Combo models only)

Your 1100 Series™ 1197c SI Combo uses Side Imaging sonar to provide a wide yet precise survey of a large

area of water, including detailed bottom topography and fish-attracting structure orientation. The Side

Imaging transducer returns are processed into an image similar to an aerial photograph.

Typically, the Side Imaging sonar can search an area that is 720 feet wide (360 to each side), with a

typical depth performance of 150 feet when the Side Imaging Sonar frequency is set for 455 kHz. The

side beams can be operated at one of two frequencies: 455 kHz or 800 kHz. Selecting 800 kHz produces

to your depth. In 20 feet of water, the wider beam covers an area

20 feet wide. DualBeam PLUS™ sonar returns can be blended

together, viewed separately or compared side-by-side. DualBeam
