I now have a humminbird 998c hdsi and a lowrance hds 7 Touch installed on my rig. I intend to compare them very carefully, keep one, sell one.
anyone have specific tests they want done?
like most buyers I couldn't tell which one I'd like the best, so now I'll take a look.
Mounting both transducers was tough, and the lowrance got cheated, but if I see lots of interference, I will switch them or just go with one at a time.
Id like to hear the results and see some images
I wanna see which makes the best cup of coffee...:yikes
Just kidding Brett...
I look forward to seeing screenshots.....especially in the realm of SI Range comparison at 800kHz...and separately at 455kHz..
Please get comparison shots at several increasing SI Range distances...ie...50ft, 75ft, 100ft, 125ft...
(Try to choose similar pallette color choices, similar boat speeds, same scan path, same day water conditions)...
Please turn off one brand while scanning with the other...

Been here....with older units. There is no answer to please all.
first look at both yesterday,
bird is brighter, much easier to see,
si is better since the screen is bigger
and brighter, more cumbersome to
use needing much adjustment , slower switching of views , scrolling speeds
lowrance is way way better in down images, most adjustments are automated and fast
moving lowrance head unit to try and kill glare problem.
moving lowrance transducer to optimal position on transom.
Pix pix pix ...
Wanna see some pix...
Rickie
they are all on my phone and the phone can't post pics for some reason, but I'll try
i send the pictures from my phone to my free photobucket account .I've got photobucket app..installed on my phone.just click on the picture Im age link and it will copy then you can paste hereQuote:

Phone pix of the screen posted here are good for examining how the Enviromental conditions may affect the screen..
Snapshots from the units themselves are better for examining detailed differences of image quality here in the forum...
Please try to get both...

the reason I only have lowrance pics is i'm use to the 998c and I know what it does well and does not do well.
I'm most interested in the HDS7 touch to see if it can adequately replace the 998c HD.
When both units are on, the create significant interference in the SI mode.
glare is the problem here,
going to move it and try again,
I love the down scan on the hds 7 BUT i still think it has to perform as well as the 998c hd on the side imaging , may check it out today again
Those are nice looking di screen shots. Got a question Brett. When you are zoomed in to a tight range on your chart plotter screen is the shore line real blurry? On my HDS touch I can't hardly tell where the water stops and the land starts. At night it is nice to know how much room you have. I don't want to eat a pier.
I'll check on it, I'm usually so zoomed in that i never see the land
I would like to get some side by side images of DI from both units at different speeds from say 0.1 to 5 mph. It you could take those images over trees/brush/rocky points tha would be great. Thanks for offering to do these test. Maybe you should just keep both and have the best of all worlds :crazy:
Why be moving it ... can you not get screenshots from it ??Quote:

no glare, no blurr, no flash, and no need for zoom ... when using a screenshot !!

I was going to move it cause I was having a hard time seeing it.
The DI comparison is a good idea, it's the only reason I got both,
I'll do my best but I can't run them at the same time, interference. And going over the same brush in the exact same way is not likely.
I'll post screen shots but what I've learned is this, a great screen shot ain't crap if you can't see it where your sitting.
I suppose if you want to go home and study it, would be worth it.
now I'll go learn how to get a screen shot from the lowrance to the pc.
I have found that dropping buoys on each "outside" of the brush allows me to get the same path over the brush again and again for comparison testing ...

Since you have gps units, why not just set two waypoints, one on each end/side of the test subjects or area, and then have the units navigate you from A to B ????? If you start on A, the 2nd run or 3rd run should be close enough for a good comparison between the screenshots
Good point jimp...and pretty effective for most testing....Quote:

There are tests I make that re-scan the same brushpile 20-30 times getting full screen snapshots every pass...(sometimes even freezing the screen and getting 3-4 separate full screen image snapshots at different settings)...
Now if I had a second unit for chart...that would be a different scenario all together...

You can go into files, screenshots, export, then send them to your sd card. I like to save mine in a folder on my desk top then move them to my screenshot folder after I go through them to see which ones I want to keep.Quote:

Gents,
you should be equally interested in comparisons of both units SI capabilities.
I have found this to be equally surprising.
STAY TUNED
I will make every effort to record both units at various settings, and speeds, as I have often read the settings are as important as the actual hardware and software
Bettw..... you've got my curiosity up on this comparisons thing that you've been doing.you haven't posted any side by side pictures that we all wanted to see and the hds that your selling on ebay well those pictures imo seem to be lacking.maybe your setup. Im not sure but i think it would be helpful to all seeing that you opened your own can an all for you to show side by side comparisons with shots of the transducer location of each.i hope that you can do this because i think this would be helpful.thanksQuote:

Where are the pics LOL.

got busy, I'm surprised you don't like the eBay screen shots

I will post pictures,
