Fish Id Sensitivity; Sonar Colors - Humminbird HELIX 5 SERIES Operation Manual

Fish ID Sensitivity adjusts the threshold of the Fish ID+ detection algorithms. Selecting a higher
setting allows weaker returns to be displayed as fish. This is useful for identifying smaller fish
species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is
helpful when seeking larger species of fish.
Fish ID Sensitivity is used in conjunction with Fish ID+. Fish ID+ must be On for Fish ID Sensitivity
to affect the ability of the Fishfinder to identify sonar returns as fish.
RTS Window sets the RTS Window to Wide or Narrow, or turns it off in the Sonar View. The RTS
Window always updates at the fastest rate possible and only displays returns that are within the
transducer beam. See What's on the Sonar Display for more information.
