A thermocline is the horizontal boundary where significant water temperature differences exist.
When a thermocline exists, it will often tend to reflect sonar signals and is therefore visible on the
display. The thermocline is identifiable because it usually exists over a broad area, and as a
result will appear more continuous than returns from fish.
