Should very strong returns from large concentrations of marine organics be encountered, then the fishfinder may indeed interpret the returns as bottom and adjust the range accordingly. Under such conditions, configuring the fishfinder's range from auto to manual and then adjusting the range to a depth which is slightly greater than the actual depth of the water will typically address the problem. Under extreme conditions, it may be necessary to make adjustments to the Gain setting to be able to separate organics from the bottom.
