The 571 HD DI features a high-res 16-level grayscale 5-inch display. The HD Down Imaging sonar with DualBeam PLUS with SwitchFire has 4000 watts PTP power output. The DualBeam sonar gives you two beams that can be viewed separately or blended together. Use the precise 20-degree beam for high accuracy returns of fish, structure, and bottom profile. Go to the wide 60-degree beam and get an ample search area for fish or structure. The Down Imaging sonar uses high-frequency sound waves emitted in ultra-thin slices to create a snapshot of what is below your boat, for an incredibly detailed image like nothing you have seen before.
