Like I said it is all based on the angle.
I can normally see my braid above jig traveling thru the water column.

To increase the signature of the sonar return, you need to have more of the signal be reflected back at the transceiver.
A spherical jighead has a single point that reflects the beam directly back to its source. The area around it will reflect the signal backwards but not perfectly. As the beams hit areas further away from the center of the sphere (assuming it is aligned with your transceiver), the return signal is weakened. You can increase the size of the sphere to allow more area that is essentially perpendicular to your transceiver, increasing the amount of signal detected.
Other shapes, such as the hexagonal nut that SuperDave referenced may increase your signal by having an even larger reflective surface provided by a single face of that hexagon (assuming it is near perpendicular to the transceiver). If a corner of the hexagon is perpendicular to the transceiver, than you will be diverting the beam at angle away from the transceiver.
There are certain shapes that can be utilized to optimize the returns.

Good info and I have read as stated flat surfaces show better then the typical round jighead, but as a new livescope guy I found using a small swivel above my jig works well, I can see 2 distinct things (jig&swivel)moving at the same speed. My typical set up consist of Hi vis braid to a small swivel then a couple feet of mono to my jig.
I can see the Teezer pillhead jigs better then the standard roundheads I have when using the 1/16 ounce.I want to give those new Hammerhead eyehole jigheads that I saw on the Crappie Magnet website,they say they show up better on live sonar.
I think as a test I’m going to squish a jig head with pliers and see if it helps any.
That's why I use a double jig rig
Quick funny story about a split shot : friend of mine uses double jig rig & his usual partner prefers minners/slipfloat. His partner was complaining about getting bites, but not hooking fish. Turned out that the fish were hitting the split shot, not the minner/hook. (my friend eventually told him that was what was happening, because he was watching it on the screen ... he just had to wait until he'd calmed down from laughing so hard at his buddy's ordeal )

What really shines is braided line.
