How is water depth displayed on the fathometer's video screen?

Explanation:
Water depth on a fathometer’s video screen is shown as numeric digits using an LED display. The sonar presents a bright LED readout of the current depth, which is quick to read at a glance, even in rough conditions. This is different from an analog gauge (a dial) or a simple echo graph, which don’t give an exact numeric value in the same readily readable way. The LED display provides a clear, precise depth reading directly on the screen.
