Fish finder-chartplotter

Fish finder-chartplotter

— this category includes models that combine the capabilities of an echo sounder (ultrasonic scanning of the water column) and a chart plotter (working with specialized charts for water navigation). Both types of devices are described in more detail in the corresponding paragraphs. Here we note that their combination makes it possible to get by with one device instead of two separate ones, however, chartplotter echo sounders cost accordingly, and in terms of specialized functionality they often lose to narrow-purpose models.
