2D/360 chart speed, jigging mode, 999ci SI 7.650 software

Rickie, I have complained about the slow (below-setpoint) chart speed in 2D when I have 2D/360 screen up. I have "jigging mode" ON. I called HB and they said it was to minimize crosstalk, I don't understand how I would have that much from (2D) 200kHz to (360) 455kHz. But that's what the said. As soon as I turn 360 "off" chart speed is back to normal setpoint speed on the same page 2D/360. Any ideas on this? I have a 999ci HD SI running 7.650 software.


I wanted to move this from Fishing Electronics "Not showing fish" to "Side/Down Imaging" in hopes of getting more comments. I jumped the thread and it got off subject.

Rickie's Comment
That answer doesn't make sense to me either ... 200kHz and 455kHz wouldn't crosstalk ...

It seems I'm faintly remembering someone else posting about the Chart speed slowing down when 2d/360 is viewed ...

I'll see if I can did it up ...

Have you tried the different "Beam Select" menus (200kHz - 200kHz/83kHz) to see if the Chart speed reacted the same ...??

Rickie

I have the same issue i think. Chartspeed increases to an unusable level when i switch from 83kh to 200kh

Moved from "Not Showing Fish"
Rickie, I think I tried 200/83 with the same result, will test again.

Kosmo, I see what you mean. One thing I noticed is you are using 800kHz on your DI. With my 999ci if I turn 800kHz "ON" it blows the 360 to white all the way till 0-1 sensitivity. HB told me I can't use 800kHz with 360 and they are aware of this issue. I thought the 360 was probably set to max of 455kHz but it must be set by what you select (455 or 800) so if I want to use 800kHz I then have to go to menu and turn it off before turning my 360 on.

I'm getting so discouraged with HB and my 999ci SI - software 7.650 issues. It has bugs and problem all over the place. I keep sending my issues to HB but have no idea when they will be working on getting them fixed. I wish they would have at least got the "now discontinued" xxx9 core units software working correctly before they moved on to the Helix. They seem to have forgot about all the loyal HB customers that still own one of the core units.

Rickie's Comments: New ... Jigging Mode copied to this Thread

Jigging mode was a recent software update to address the HB 2d complaint of "over pixelation" (HB SI units only) ...

When HB released the 360 software (6.570) ...they also decided to make a change in the unit ping sequence to enhance imaging (DI/SI) ...

This was accomplished by having the unit transmit the SI signal more often in the ping sequence by decreasing the amount of 2d transmit pings ...

This decreased the amount of 2d info being obtained to plot into the 2d image ...

To keep the 2d image scrolling correctly (with less 2d data) the unit must copy vertical rows of pixels (double pixeling) as it is plotting the vertical rows on the 2d image ...

This causes a "blocky" look to the 2d image ... Which many 2d users did not like ...

Instead of abandoning the new ping sequence (with enhanced SI pinging) ... HB added a user selectable "Jigging Mode" which tells the transmitters to revert the ping sequence back to the ping sequence before 6.570 ...

So.....
"Jigging Mode On" is better 2d (with lessened SI pinging) ...
"Jigging Mode Off" is better SI (with lessened 2d pinging) ...

You may not see the difference in the SI image ... But you will see the difference in the 2d image ...

Rickie, are you saying that Jigging mode "ON" in new software is back to the original ping code?

HB:
*Jigging Mode - this is a selection in the 2D Sonar Express Menu. It allows the user to select the sonar ping pattern for use while vertical jigging. When turned ON the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, repeat. With this mode turned OFF the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, Left SI Beam, Right SI Beam, repeat. Basically this feature prioritizes the 2D beam over the SI beam.

Zippy, what HB unit, and what software version are you having the chart problem with?

You are correct.360 is 455khz only.I found out the same as you.If my 998 was set too 800khz,then when 360 was turned on the unit would ping the 360 on (what appears to be the 800khz).Acually,in some cases,this turned out to be better."software glitch".This doesn't happen on the onix.
On the onix,when 360 is pinging while the 455khz,si/di is pinging.There will be crosstalk ,interference on the 360 screen.This is easily fixed by either turning pinging off to si/di or changing si/di pinging to 800khz.

In this picture,using contour mold.You can see some missing data.I think that the ideal for changing the pinging priority to si/di,was to get extra pings to minimize the missing data, (helps the di) ....http://i826.photobucket.com/albums/z...syeczvksm.jpeg

This picture is from the 998.my boat is moving 0.3 mph.The slower 2d scroll makes the individual fish stand out,along with the structure. ...http://i826.photobucket.com/albums/z...pso17y7phq.PNG

I don't have 360 ... But I do notice the Chart speed increases when 200kHz only is selected in the "Beam Frequency" menu ...

I assume it's because the 83kHz is no longer in the ping sequence ...

Sometimes I set the Beam Frequency to 200kHz and then decrease the SI Chart speed 1 or 2 clicks below boat speed ...or until I see the individual pixels not "stretching" (which is basically the unit copying and repainting the same pixel data repeatedly) ...

I do not know yet if this the case with the 2d/360 view ... I'm still looking for similar discussions on the other forums ...

Rickie

Rickie, if the slow chart speed (2D) is needed as a result of the anchored to very slow speed the 360 was designed for to stop the pixels stretching, then I understand why they might have installed code to slow the chart speed down. I tried different sweep speeds on the 360 but that did not change chart speed, that I could tell. You can go to 10 chart speed and it does change the 2D chart speed a little in the 2D/360 view.

I normally like the 200kHz in 2D. I want a small cone angle to be more accurate concerning when the cover or structure start showing on the right side of the 2D screen the transducer is over it. Even with .35 X DOW with the 200kHz, 40 feet water depth the bottom coverage is 14ft diameter circle. If fish are holding tight to a 2 ft. diameter stump I still will have to work to put a jig on their nose. With 83/200kHz the coverage is 1.0 X DOW that will be a 40ft diameter circle.

Thanks you for any info you can find. Rickie
