  • Two selectable frequencies

            Two types of the broadband transducer are available for your                        choice.
            Two selective frequencies can be set and changed during use                      within the ranges below.
            TDM-071 (38 to 65 kHz)
            TDM-091D (42 to 65 kHz, 130 to 210 kHz)
            Flexible selection of frequencies by 0.1kHz step enables the user                to stay away from interference with the sounders on the other                      vessels.

  • Koden Digital Filtering (KDF™)

            The Koden Digital Filtering (KDF™) technology has enabled low                  noise, high resolution and outstanding distance of detection.

  • Detection area display

            Know exactly the bottom area covered by the low and high                          frequency sound beams. This can help you target the fish directly                under the boat or off to the side.

  • Store Image

            Stores up to 10 screen images in built-in memory for recall later by              a single touch.

  • Sona-Tone™

            Exclusive Sona-Tone identifies what’s under your boat with                          different sounds for fish and schools of fish.

  • Auto Function

            Takes the guesswork out of operating the sounder. Even a novice                user can achieve professional results by letting the CVS-128B pick              the optimum settings for such functions as Range, Shift and TVG.

  • Connection with JB-38

            You can connect to existing transducers using JB-38 (Option).
