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....

Side Imaging is by far the best... You need SI. I really don't know why HB built a unit without SI. Seemed like a bad move in my opinion.... SI is the way to go. Get the 1198...

I use the ISF feature the most!
ISF....:confused:Quote:

Until HB gets the ability to put a true di crystal in their si puck there will be a use for these units. I think of them more as an addition to what you already have versus a stand alone unit. I would never buy a 10 " di only unit but the smaller ones fit the bill. The difference in image quality between di and di from si is pretty substantial from what I have noted so far.Quote:

Will it be just buying another transducer or will it be a change in unit as well ?

This is the "rumor" I speak of....
It was posted in this thread....Quote:

There were immediate questions asked..but as of yet Jason has replied with any confirmation...

This is the only question I saw:
"Jason, do you know if you'll be able to retrofit older models...ie 1197 .... with upgraded transducer /software to use dedicated di crystal ? Not saying I would, but just wondering."
The dedicated Down Imaging units (1158c DI, 958c DI, 858c DI) use different technologies and transducers to produce their Down Imaging that do the Side Imaging units (1198c, 998c, 898c, 798c). As far as I know, each family of units will continue to use its own particular transducer.
Jason.. From your previous post that I quoted... It seemed to me (and maybe others)... By stating "11xx, 9xx, 8xx, etc....That you may have been eluding to the possibility that the 2012 SI units where going to incorporate dedicated DI crystals...Quote:

You are reading too much into what I wrote. The 2012 Side Imaging units (1198, 998, 898), the ones hitting the shelves right now and that we'll all be using to catch fish next season, use the same HDSI transducer that has been successfully used for years. The 2012 DI units (1158c DI, 959c DI, 858c DI) use the new dual beam + Down Imaging transducer.
My apologies... I'm glad you caught my rumor before it got out of hand... Thank you...Quote:

Dedicated DI crystals has understandably become a very important factor in people's decisions on which units and/or brands to choose...
Your information is greatly appreciated in this forum...
