don, some of these pictures can be deceiving because of the different conditions that can afect the sonar.the bottom line is that di/from si is what it is.sometimes a person can get some really great images if conditions are right but at other times not so great.in most cases, like rickie post above, the 455 khz will give the best results from the di from si.accually you can see why by just looking at rickies pictures above.thats a soft bottom in those two shots.see whats happenning close to the bottom in the 800 shot
