Fish detection

Fish detection options are available when using Raymarine® transducers.

The Fish detection feature is only available when using the SONAR channel.

The Fish detection feature can be accessed from the Fishfinder app menu: Fishfinder > Menu > Settings > Fish detection

Fish detection Fish detection options include:

  • Fish detection Fish detection beepFish detection beep — An audible 2 tone beep is sounded when a sonar target is detected that the fish detection algorithm considers to be a fish.

  • Fish detection Fish iconsFish icons — A fish icon is placed onscreen over sonar targets that the fish detection algorithm considers to be fish.

  • Fish detection Fish depth labelsFish depth labels — The depth of sonar targets are displayed next to the target that the fish detection algorithm considers to be fish.

The fish detection feature can be adjusted manually as follows:

  • Fish detectionDetection sensitivityDetection sensitivity — The detection sensitivity setting determines the size at which sonar targets are considered to be fish. The higher the value, the more sonar targets will be considered to be fish.

  • Ignore fish shallower than: — Specifies the depth at which the fish detection algorithm will be used.

  • Ignore fish deeper than: — Specified the depth at which the fish detection algorithm will stop being used.

Using these options allows you to specify a depth band of water where you will be fishing and the size of the fish you want to catch.
