The Humminbird 571 HD DI is a monochrome unit, with quite a wide screen, 5-inch in diagonal, 640 x 320 pixel resolution 16 LvL greyscale. It’s an HD unit, delivering images of higher accuracy, in SwitchFire and Down Imaging.
It’s sonar capabilities are similar to the ones of the 561 DI model: 00 kHz / 28° or 455 kHz / 16° in SwitchFire mode, and 800 kHz / 45° or 455 kHz / 75° in DI mode. The unit is listed as reliable for 600 feet depths in classic sonar mode, or 350 feet for Down Imaging. However, Down Imaging may not be as accurate in waters over 200 feet deep.
