Same for me although my unit will pick up the anchor and cable that secures the floating dock at the ramp as clear as hi-def TV.
Jigging has to do with sensitivity, ping speed and chart speed. None of which we can adjust on these units so they are not good for that.
Also, arches won't show up as noticeably as they do with traditional sonar. Think of it this way....DSI is a 1080p hi-def and lower frequency or traditional sonar is like cable TV or VHF (if you remember VHF). Lines are thicker with sonar and thinner with DSI. Therefor, arches are thinner and not as defined.
I am frustrated with this units lack of being able to adjust ping speed, chart speed, and sensitivity as it would help me see the arches better. I have seen this first hand with HDS units like the HDS 8. (Hi definition screen). HDS units also have a better pixel rating (more pixel capaciry/ higher definition) meaning its able to show crisper imagery vs the Elite series. At least I think this is correct....
