This device’s 2D sonar offers a whole lot of useful functions. Among these, there will be the A-Scope, UltraScroll, Flasher, Auto Gain, Fish Symbol ID, Split-Zoom, including different alarms. For persons who aren’t acquainted with these functions, here is a quick explanation of some.

The Fish Symbol ID function processes the sonar returns in several ways and adds different fish icons to them. Besides that, it shows the depth of every target fish. It’s simple to see how useful this could be to every owner of the Striker 4.

The Flasher mode is a depth scale in circular form. In addition, it provides information on targets found by the sonar beams. The Flasher’s inner rings show depth, and the flashing segments on the outer rings show different sonar returns measured in strength. This function will come in helpful when ice fishing or fishing from a stationary position.

The A-Scope can be a flasher function. The difference is that it offers information in a vertical layout about the newest returns from the sonar.

The Auto Gain function gives users the opportunity to let the unit filter unnecessary noise without manual adjustment.

With Ultrascroll, you can scan while moving at high speeds. It permits faster scrolling of the sonar data. But, if you are exceeding 40 Mph, image quality are affected.
