Fish finders with auto-change depth scale

Auto-change depth scale

— in most cases, it is most convenient to work with an echo sounder when the water column “visible” by the device from the surface to the bottom occupies almost the entire vertical space of the screen. However, the depth under the bottom can change noticeably, which requires reconfiguring the scale. This function, as the name implies, allows such reconfiguration to be carried out automatically — so the user will constantly see the image at the optimal scale, without being distracted by adjustment.
