The images presented on the echo sounder displays included in this article may not accurately reproduce the real color hues shown on the displays of the actual echo sounder used, due to digital cameras used and printing conditions. In particular, inserted images of the reflected signals which seem to be orange red (representing the bottom of the sea or fish) are shown as more reddish on the actual echo sounder displays.

The Latest in Digital Echo Sounders
Echo sounder with "next level performance" is the talk of the industry. This report documents the latest trends in echo sounders. The latest topic with respect to echo sounders intended for pleasure boats is the advent of so-called "Digital echo sounders" It is said that the digital echo sounders, in comparison with the analog ones, offer advanced detecting capabilities that are one or two steps ahead or are capable of distinguishing fish schools near the bottom of the sea from the bottom itself. Do they really deliver such outstanding performance?
We have checked true capabilities of digital echo sounders in cooperation with Mr. Isao Toji called the "Boatman Tama-chan" who supports our "Hands-on Fish Detection Training" column.
