Essentially, because they are compressed, the downscan images with 3D are exaggerated compared to those from LSS-1. As a result all gradients appear steeper. It’s probably something I just need to get accustomed to & I wouldn’t let it put you off the purchase.
What is evident is that although “fish reveal” may help to identify fish targets (too early to tell yet for me) actual downscan imagery from LSS-1 (at least in shallow water) is better than from 3D. However, sidescan imagery from 3D blows everything else from Lowrance away in terms of both clarity and range.
Its puzzling that in over 7 years the downscan technology hasnt improved whilst sidescan has moved on in leaps. Maybe this will be something that the power of the Carbons dual processors can take advantage of in the near future.
