I posted this fairly deep in another thread but since there has been so much discussion about this I thought I would make a thread just for it. I'm not saying it proves anything but at the least it is some anecdotal evidence from one specific situation. Situations are different and individual results will be different too.
The left side is v2.00 original as came on the GLS10. The right side of the screen is the v2.41
When four jigs were used the top two are 1/16oz and the bottom two are 1/32oz. There are 4 jigs even if you only see three. When seven jigs were used all were 1/8oz. There are no snaps. Jigs tied directly to line.
I alternated which transducer was connected to each GLS10. One was mounted on the torpedo and is named FOOT32 onscreen. The other is up on the shaft and it's named Shaft32. Only the right side shows the name so the left side is whichever one the right side is not. Since there can be a difference in transducers I switched the transducers back and forth on the boxes but maintained proper identification. Both transducers are canted. A lot of the videos have NR and TVG off. I think those settings give a better representation of what the transducer can see. Filtering can hide both unwanted and wanted returns. So you'll have to tolerate ghost trees. As you'll see there is quiet a bit of interference.
The significance of the file names.
Jx x is the number of jigs, either 4 or 7
G?? Gain 60, 70 or automedium (am)
NR??? off, low or medium
TVG ??? off or low
ShaftFoot or FootShaft. Left to right on screen of which transducer was used.
When I focused on a specific range I included that range in the filename.
I'm lazy. The easiest way for me to share these videos is to link them in my Google Drive. Here is the link.
There are 16 videos. You may want to look at them or may not.

Some of you may have requests for additional comparisons. I'm not doing that. I borrowed the box and returned it. I am paranoid about borrowing stuff. Usually when I borrow something I end up having to buy it. This guy fishes too and done me a favor loaning me his box. Good or bad, as they say it is what it is. Also, I am not including any interpretation. Judge for yourself.
The weak and dead spots reported on seem related to the ghost trees. The ghost trees are related to depth and bottom type but also affected by the incline of the bottom and nearby banks. When you filter out the ghost trees it's inevitable that targets of similar strength and weaker will be filtered out. Thanks to Roy, Gene, pfisher and others for focusing attention on this. It has changed how I fish. Lately, I no longer adjust the settings to eliminate the ghost tree.
Here are some samples of ghost trees. NR and TVG were both OFF.
