Does anyone notice that one side of their side image show a brighter picture than the other, including on the flats in same water depth on both sides of the boat ...why ?

Which side is brighter? If it's the left, could be some interference from motor. What unit are you running? Need more info.:dono
I've noticed this with mine also, and the left side is the brighter of the two. Not terrible but just enough to notice. Kinda thought it may be motor interference.

If I'm searching I'll tilt my motor up a little and then both sides look fine.
Left side always seemed brighter even if I had the unit on a different boat over time or even if I have it on an all electric boat with a dedicated battery Lowrance HDS 12 G3:dono
Never noticed that but next time out I will check, Thanks.
Perfect symmetry, with both sides transmitting equally and perfectly plumb, is an ideal rather than the reality in most installations. Unless you have that TD perfectly centered and plumb to the water, you might have a little shading. I adjusted my TD until it looked the best and called it good.
The transducer off level can cause one side to be different because the side turned up will be lighter than the side turned down. Being off level could be the way the boat is loaded.
I've tried most of the suggestions even doing so with an independent battery...but I'm still stumped. I might go on to say I've even mounted it on with a removable bracket where I can at any time adjust it left,right or tilt up down mount left side or right side of transom. I can use it with an electric motor,gas motor or no motor on transom same results left side picture about 20+ % brighter:dono
The lighted left side could be cause by the driver being on the right side making it more heavy to that side.

Not to hijack this thread,but since it’s talking side imaging I hope it’s ok.Question- Does it matter which direction the transducer is pointing ( flat end vs tapered end ) I use a side arm mount on my kayak, hanging the transducer over at the beam.
The SI signal is sensitive to even tiny differences, for example bubbles in the water from your previous pass over an area, or another boat's bubbles. Make sure the transducer is level front to back and side to side as the boat sits in the water loaded the way you usually fish. There is a you tube video when a man took a carpenter's level and put it on the gunwale of the boat sitting in the water, then put pennies under the low end to make it level, then counted the pennies, so when it was on the trailer he could use the tongue jack to return the boat to that position out of the water, and then level the transducer to that. The other thing that could cause it is bubbles from the bottom of the boat, such as from the "runners" on an aluminum boat.
Just a shot in dark... is trans... mounted on centerline..of hull...????? maybe that could be a factorQuote:
