Location: Grand Rapids MN | I don't have one but I remember some of the differences/benefits of DI with one being how the sonar beam is emitted and the picture displayed. Traditional sonar is a cone whereas down imaging is a narrow beam. While fishing breaks/edges you get some amount of false bottom (depeding on steepness, depth, etc) so you could miss bottom hugging fish or ones just at the transition whereas DI will give an image of the bottom and break edge showing those bottom details.
I had seen a tournement walleye angler video show a side by side of 2d and DI of this very example while prefishing. That really stuck with me since I walleye fish a fair amount and fish similar structure. Some day I will pull the trigger on one of these new units. I would really like SI as well.
Hope this helped some. |
