Fish echoes around structure and in mid-water.
The selected display mode is the new "Sunlight" color mode, available on TZT9F/12F/16F/19F v3.01 and TZT2BB v9.01.

ECHO STRETCH
CHIRP processing gives sharp echoes, but small targets may be hard to see. Echo Stretch thickens echoes, making targets clearer from a distance or in deep water.

TRANSMISSION AT PRESET FREQUENCY
Up to three frequencies can be saved and selected instantly. This allows quick adjustment for different depths, fishing areas, and target species. It also helps reduce interference from nearby vessels and ensures the best signal for bait, game fish, and deep-water scanning.

SEQUENTIAL TRANSMISSION
In addition to simultaneous dual-frequency transmission, the DFF3-UHD offers a new Sequential Transmission mode (Sequential A / Sequential B). This mode alternates frequencies instead of sending them together, which helps reduce side-lobe effects around the seabed and improves clarity of bottom targets.
