Need a little help here. I'm getting ready to
make a (big for me) upgrade to the sonar on
my boat. I've been using a FishMark 320 and
want to get a side imaging/down imaging sonar.
I want the big screen.
What is the difference between these two units ?
From some descriptions on the internet they seem
to do the same thing, but one is $500 more than
the other. I'm sure I'm not reading everything
right.
thanks, Chris
Do a youtube search for Side Imaging and then on Down Imaging, that will probably explain it better than someone trying to type it out for you. But they are not the same, as the names suggest the side looks out to the side a lot further than the down imaging will or can. Good luck.
Hi Little Skeeter
Yes, I've researched this some. This YouTube video is on the 1158c page on
the Humminbird website. From what they are saying here, the 1158c has
2D, down-imaging, and side-imaging and can display all three at the same
time on the screen.
What can the 1198c do that this unit can't ?

thanks kindly, Chris
1158c is 2d only
1158c di is 2d and true di only
1198c is 2d si and di from si conversion
all 3 have gps
lcookie is right:
1158c Combo is 2D (conventional) sonar only.
1158c DI Combo is 2D sonar + (true) Down Imaging sonar.
1198c Si Combo is 2D sonar + Side Imaging sonar + Down Imaging sonar (derived from the Si sonar beams).
All have GPS since they are “Combo” units (combined sonar + GPS).
You have to watch those additional letters in the model name and make sure what you are buying as all retailers do not use the correct model names.
Chris, where, in that video, did it say the 1158c has side imaging?Quote:

Here are a few examples of how I use these technologies for crappie fishing:
Using Humminbird sonar to stay with roving late summer crappies
Finding summer crappie with Humminbird Side Imaging and VMC jigs
Fall fishing hotspots revealed by Humminbird Side Imaging
Mid-summer panfish revealed by Humminbird Down Imaging
Targeting spring panfish with Humminbird Side Imaging
Currently, I run an 1198c at the console (Dual beam, SI, DI) and am installing an 1158c DI (dual beam and DI) that can be moved between the bow and the transom for trolling applications.
I think I see what you mean. Even though the video says that you can show show down imagingQuote:

I made evidently the wrong assumption that if this video was on the page for the 1158c that it
would be describing it's attributes. Likely this is a generic down-imaging video that they threw up
on the page.
I will most definitely will NOT get a $2000 chart that does not perform side-imaging.

No big deal. I'll just sell something else. :)

You won't be sorry for waiting and getting SI....
SI is amazing....
