Simrad SX90 Fish finding sonar

Features and functionality

The Simrad SX90 fishery sonar provides you with an impressive range of advanced operational features and functions.

User selectable beam width

Simrad is often first with new sonar features. We now provide you with user selectable beamwidth.

This feature provides improved range and better resolution in the horizontal picture.

When you search for fish at long distances you will set the beamwidth to "narrow" for maximum detection range. When you approach the fish you will use shorter range. The sonar can then be set to change beamwidth to "normal" or "wide" automatically, or you can select the appropriate setting manually. The beamwidth is frequency dependant.


  1. Wide beam
  2. Normal beam
  3. Narrow beam
