dark on outer edges of 106sv side view
my 106 has both dark edges sometimes, sometimes one edge, and sometime no dark edges can someone tell me what causes this. i have a humminbird mega mounted beside it and doesn't have this ,both transducers are mounted on back of boat one on left one on right
You didn’t say what frequency youre using in what depth, but it’s probably at its limitations of range.
using high frequency set at 50 to 60 ft, most time less than 20 ft
What transducer? Any pics?

gt54 no i will get some next time out
look like this?
yes but not as bad

1120 hz is only good for about 30-40' out each side....even the manual says it has a 30' max depth....go to 455 if your try to get distance......you really have to play with contrast and brightness with Garmin....as well as different color pallette....they are decent when all dialed in and you know the limitations.
GT54UHD Specs:
ClearVü: 0.94°x60° @ 800 kHz
SideVü: 1.62°x50°
UHD SideVü: 0.441°x52° @ 1200 kHz
So 52 degrees each side at most. There’s at least 38 degrees of “blind spot” each side.

WOW, 30 to 40 feet max wide on SI is really weak!Originally Posted by Gford
You keep saying this, and it’s completely BS. What manual are you reading?
MAXIMUM DEPTH CHIRP: 800 ft.; ClearVü 200 ft.; SideVü 500'; UHD SideVü 125'
Its a matter of simple geometry, angle and depth are all you need to calculate the range. Perhaps you have your SideVu range limited / zoomed, or in shallow water?
If I recall right I get around 60 each side in my usual 25’ +/- 5-10 ft of UHD side
I’ve seen the same effect, yet not that ‘bad’. The 1120 and 455 need separate contrast levels, that sadly need to be manually adjusted, unless I’m mistaken. I think it’s displaying that the water depth is increasing, yet poorly exaggerated, IMO. If you turn the contrast up, you’ll be able to see the dark areas. Unless the depth dropped off steeply enough that the sonar couldn’t bounce off it. I could be wrong about that theory. Do you have any interference issues? Could likely be coincidence but I don’t recall seeing that effect as much after I solved my interference problem.

put angle ∠β=52°, and A as your depth and calculate. B will be your range. At 125ft deep it’s just shy of 160 ft wide on flat bottom.
