I have a HB 698 that I have never been happy with.... was out in the shop today and decided to mess with it yet again..
Question is, should you be able to adjust the si settings in simulation mode to achieve a clear image..... I can make adjustments all over but cannot get a clear image at all very grainy,,,,
The Simulator is a recording that is hard coded into the unit memory ... But you should be able to adjust the settings to get it clear ...
Press the "Menu" button one time to open the SI Xpress "Menu" ...
Then choose "SI Enhance" to overlay the SI Enhance "Menu" over the SI image ...
*Turn off Sharpness ...
*Lower Contrast to about 10 ...
*Adjust SI Sensitivity to brighten/darken the SI image ...

I have ran contrast and sensitivity from one end to the other and every where in between..sharpness is off ,its either grainy or washed out, Maybe I am just expecting a better image than this unit is capable of... I will take a pic of the best looking screen and post it... and y'all tell me what ya think.
Is it possible you have the screen brightness turned up too high .... do a quick press of the power button and see if a brightness adjustment helps.
Wouldn't hurt to wash down your transducer, too. Road film, and other films from the lake may be coating the transducer. :dono
THE 798 IS A SMALL UNIT BUT IT WILL GIVE YOU ONE OF THE BEST PIC AF ANY UNIT IN IT'S CLASS,I HAD ONE
Be sure to match Chart speed to boat speed when viewing SI ...

Here is a few pics... again these are of the simulation screen.... I understand all this means little once out on water, but I am trying to eliminate transducer issues as a factor in poor images...
I think the pic with sensitivity turned down looks the best...but have no idea what that will translate to on the lake.... Thanks for any input.Attachment 247798Attachment 247799Attachment 247800Attachment 247801
Looks like chart speed is set to high. Slower chart speed will help clear up the screen. Like Rickie said match the chart speed to boat speed. This may also be a help.:twocents

Midcarolina, some hardware issues, limitations to be aware of. I'm not sure what the pixel rating on the 698 is, that may be part of the graininess. also the "8" denotes you have a HD transducer and not the compact trasnducer, at least check that. I have both types and the HD is much clearer than the compact. Another thing on my SI settings I run my contrast just a click or 2 below the sensitivity number and I also run sharpness on low. The HD ducer will have the temp probe visible on the back end of the ducer, looks like a little silver button.
Thanks for the info.... I think I am on the right track now My problem was I kept doing little tweaks on the sensitivity and contrast and for some reason mine wants a farther adjustment than that... Here is a pic taken on the lake yesterday of my screen, now keep in mind it's a picture of the screen using my smart phone.Attachment 248238
Looks like you have the SI enhance turned on .... that will give you a little more grainy image, but make fish show up better.
Wow! Looks good. I will be looking forward to seeing your fish reports and sonar pictures. :highfive:ThumbsUp
The numbers naming convention no longer hold true for XDCR type.Quote:

It is very similar to my old 797c2 (640v x 480h) except an external GPS is not plug and play supported.
The Helix 5 SI GPS was meant to replace that with the 480v x 800h pixel matrix - sort of like turning the display sideways and allowing better SI horizontal resolution.
The SI Enhance sure does help fish "pop out" but does make the images quite grainy.
