I have a pair of 587 cihddi humminbirds. If I go into my menu and select 455khz on my 2d sonar I loose signal. If I am on the split 200/455 2d screen the 455 is blank and 200 is normal.
This is the same on both units. They are on separate ducers and not connected in any way.
Ist there a menu option I am missing or do I have a problem?
I might be guessing here .... but, I was under the impression that 200kHz is a 2d sonar ping and 455kHz is a DI sonar ping. I wouldn't think a 2d processor could even interpret a 455kHz signal, or a DI interpret a 200kHz signal.
From what I've read about this unit ... the 2d imaging is done with a dual beam 83/200kHz signal ... and the DI is done with a 455kHz signal. It is capable of split screen images, either the two 2d signals or the 2d & DI signals. What I don't understand is how you can choose the 455kHz signal for the 2d imaging :scratchhead ..... shouldn't the kHz signal automatically relate to whichever imaging view (2d or DI) that you choose ??

That one got me too crappiepappy. would also see it as not being able to interpret the signal coming in unless it was compatible to that screen you were using.
The HB dedicated DI units do not use the "usual" 83kHz/200kHz frequencies for 2d...(unless it's a 800/900/1100 series DI unit and the "Transducer Select" menu is set to 83kHz/200kHz...and a compatible XTM 9 WIDE DI 20 T is attached)...
The smaller HB DI units only have the options of the beams below..

toofus...are you talking about changing the "Beam Select" menu from 200kHz to 455kHz...??
Or are you talking about changing the "Digital Depth Source" menu from the DI beam to the 2d beam...??
I think both of these settings should be under the Sonar tab...

Its giving me a beam select option of 455 along with a di beam option of 455 or 800. My units came with the XNT 9 20 DI T. No WIDE listed in the pn. I was thinking the same thing on the fact there should be an 83khz option but there is not
I will be on the water all day today and I will snap a pic of the screen to post.
Your 500 series DI unit will not have the option of the 83kHz in any configuration...nor will it have the option of using the XTM 9 WIDE DI 20 T (these options are only available on the larger HB DI units)...Quote:

Is the above 455kHz 2d "Beam Select" setting the issue you mention that causes the 455kHz view to be blank...??
Are you referring to the Sonar Zoom view that shows a split view of the chosen 2d beam and it's zoomed twin in the same view...and 1 of these panes in the split is blank...?? (There are settings in this Sonar Zoom split view that could cause that pane to be blank)...
Rickie
If I flip to 455 I loose everything but di.
OK ....
According to the manual ... (pdf version) ... page 4 / DualBeam Plus Sonar ... it states that the 587ci HD has a 83/200kHz beam ... but it does state this is for "DualBeam Plus" models only, so that eliminates your unit, since yours is a 587ci HD DI model.
Then on the next page (pg5) Down Imaging Sonar ... it seems to indicate that it can produce a conical sonar ping using either the 455 or 200kHz setting, and shows the same graph that "rnvinc" posted.
I was not aware of any unit being able to use 455kHz in a 2d sonar. I stand corrected.
I'd get a hold of HB Greg and see what he says about this situation. It's obvious I'm out of my league, here, and I apologize for any confusion I may have caused.

Unfortunately, the manual for the 500 series units is an "all in one" manual that includes both the HB "2d sonar only" units (which have 83kHz-200kHz 2d beams)...and the HB DI units (which have 200kHz/455kHz 2d beams)...
This makes the manual very confusing...(I hope HB is listening)...

Are to talking about the 455kHz "Beam Select" setting or the 455kHz "Imaging Frequency" setting...??Quote:

Same thing I said when they first started putting the different sonar type units together like this.
Not sure why the 455kHz 2D sonar would not be working. If it were software related, all DI model unit owners would be posting about this. Hard to believe though that toofuss has two units or transducers with the same problem though.
History lesson of the day: Humminbird first used the 455kHz frequency as a conventional 2D sonar beam way back in 1988 in the TCR 101, TCR ID-1 and TCR Color 1 units then later in the Platinum 120. These had the option of the (standard) 16 degree beam or the wider 40 degree beam.
Ricky when I am selecting 455 it is listed as beam select. Then below that is the imaging frequency option.
Toofuss,my 597 has the 200/455 option for 2d.the 455 2d works on my unit while out on the water but doesn't show anything while in simaltor mold
I tried it again today on the water and I got a very weak return on bottom. Had to crank the sensitivity way up to get that
Toofuss,restore defaults and give it another tryQuote:

Look under the Sonar tab for a setting called "Digital Depth Source"...change that setting from what it is and try again....
If it still doesn't change the issue...try swapping the xducers and test....
So are you getting a good bottom return (in both of the split panes)...as long as the "Beam Select" menu is set to 200kHz..??
Rickie
No even when set to 200 that's all I'm getting. 455 is screwy no matter what settings I use
Ok...try swapping the xducers and test....Quote:

Done it. Identical units front and back. Both act the same. The bow setup has a newer ducer due to me pinching the cable. You actually have the original. What's worse is I don't know how long its been like this. I just started trying to play with different freq in 2d. I got these units early last summer. I've got a buddy with a 597 on the bow. Might try his unit on my ducers and vice versa to see what happens.
Thanks, I am learning as I read.
I hope we both learn something
Make that...I hope we all 3 learn something...!!Quote:

toofus...just for clarification...
Your issue of no bottom detail showing with 455kHz selected is while on the water live...correct...??
Rickie
Yes. On the water I get a very weak bottom signal but again I have to have the sensitivity way up like past 12 or so to even get that
Like you mentioned ...it would be a good idea to test someone else's unit on your xducers to see if it's a xducer(s) issue...Quote:
