Ya but looking at structure is also important to some.... With mega Is phenomenal at.... Beautiful thing to have 3 frequencies option with the tap of the finger.

SI at 1.2 MHz:
if you can tell what the object is with 455(example being stump) and can see the bass beside it, why do you care if you can see the individual roots on mega if you can't see the fish as well or at all? Same thing with down imaging, when crappie fishing I can see each individual fish in a tree or stake bed with 455 on onix clear as can be.

The mega frequency doesn't give as hard of a return off swim bladders that the lower frequencies do. On di, you have to crank the sensitivity up to where you pretty much wash the bottom out in order to see the returns off fish.
I use mega for side and 800-455 for down depending on how wide of a cone I want. To me, using 1.2k to scan on di doesn't make sense because of how narrow the cone is.
The only problem I have with 1.2 k for si, is when the fish are sucked to the bottom, I can not see the fish return, but I do see their shadows.
So is the Mega better, worse , or the same for seeing fish?
Lowered the scroll speed a hair below boat speed and started seeing fish+shadows instead of just shadows on mega si
Nice I'll try that out
I have 2 Helix 10 gen 1 and I have a hard time seeing schools of fish on down imaging. I can switch to side scan and 2d sonar and see them better but its nothing like my buddies Lowrance HDS units. Can someone post some pics of the 1100 or helix gen 1 and gen 2 series so I can compare to this?

Ive been curious as this as well. Dedicated down imaging crystals is the key. I just called humminbird and they told me that only the DI units (gen 1 and 2) or the mega SI units have the dedicated crystals. I would really like to see the comparison between the lowrance and humminbird DI though.

Yea my helix will look nothing like that. lol I even set it up to 800hz to try and get a better picture but the SI was ok but the DI sucked. I don't want to sell my units just to get the megas but I may have too.
