- Using markers in the ST90 user interface
  Under normal use, the ST90 system presents several different echoes simultaneously. Some of these are clearly more interesting than others. It can be a challenging task to tell these echoes apart. It can also be hard to keep track of the different echoes as both echoes and your own vessel move. To ease the identification of these echoes you can use markers.
- Using target and position tracking
  The phrase target is used to identify an echo in the display presentation that you wish to act upon.The echo may be from a material item, a shallow, reef or rock, or from fish, fish schools or mammals.In most cases, the target will move and continuously change its position relative to your own vessel.You must decide which echoes that shall be classified as targets, and whether you shall start manual or automatic target tracking. A position track permits the ST90 system to automatically control the tilt and bearing based on the movements of your vessel.
