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 the sharpest image but the search area to each side and the depth capability are limited as compared to the 455 kHz frequency. See What’s on the Side Imaging Display and Understanding Side Imaging for more information.

DualBeam PLUS™ Sonar

Your 1100 Series™ Fishing System uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ sonar has a narrowly focused 20° center beam, surrounded by a second beam of 60°, expanding your coverage to an area equal 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 PLUS™ is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.
