I have a brand new 859ci hd di and the depth readings bounciness all over the place.  All other readings are right (temp, speed, gps, etc).  Was fishing in 150-200' of h2o, and the depth would vary from greater than 200' to merely a few feet, most of the fourth dimension information technology displayed a few feet.  Also had 'bands' across the screen display making information technology pretty much useless.

This is my second HB, so I'thou pretty sure the unit of measurement is installed correctly and all wiring and connections are secure (I've double and triple checked everything).  Battery voltage is about 12.2 volts, and voltage at the unit is the same.  All settings accept been reset to manufacturing plant default.  The latest software update is installed.

Called Humminbird and they suggested I gear up the max depth to x% more than the depth where I'm line-fishing.  Didn't work.  They and then went on and on about interference, shape of the gunkhole, connections, etc, all of which seemed like excuses to me.  I've had other units without a problem.

I gotta believe the transducer is faulty?  Whatsoever other ideas?  I very nearly threw the whole thing in the water.

Welcome to the Humminbird Side Imaging Forums JohnT.

Just a estimate here but your unit is a DI model unit and by the default setting information technology should be using the DI sonar to make up one's mind water depth.  150+ feet may be all that it is capable of where you lot were at and then try setting the Digital Depth Source menu to the �2D Chemical element� setting.

What type of water were you in?
Did you try irresolute the Surface Clutter menu setting?
Did this depth reading problem only happen when the boat was moving to a higher place a sure speed?
Did this depth reading problem just happen when something else on the gunkhole was running?
Practise you lot have a Screen Snapshot of what the display looked like when it was doing this?
Do y'all know of anyone else who has a Humminbird DI model unit that you could cross-examination with on the same torso of water?

[EDIT: Added "Digital Depth Source" to opening statement.]

All good questions, here'southward my best shot with answers:
I was primarily using a split screen displaying both standard sonar + DI.  Peradventure that caused the trouble?  However I did attempt just the standard sonar with same results.
Freshwater, very articulate.  Depth wasn't an outcome with my previous unit which had DI.
Yes, I played with the surface ataxia settings with no comeback.
Problem occurred in both moving and still in deep water.
No other electrical items were running.  I was running the kicker motor that is on the opposite side of the boat.
No, I did not capture a Screen Snapshot � didn't know I could do that?
No, I don't know anyone else who has a HB DI model.  HB isn't real common around here.

�Depth wasn't an consequence with my previous unit which had DI�
What was your previous DI unit of measurement?
Is this using the aforementioned transducer or is this the transducer that came with your 859ci HD DI unit?
Where is the transducer mounted, off the transom or within-the-hull?
Is this the aforementioned location as the previous DI transducer?
Exercise you still accept the previous DI transducer that y'all could use to test with?

Screen Snapshots are not hard.  Just install an SD or SDHC memory card, set the Screen Snapshot carte (found under the Accessories menu tab) to �On�.  When yous desire to make a screen snapshot just press the MENU button (also marks a waypoint) and the resulting *.PNG file volition be sent to the memory card.

I had a 597ci hard disk drive di
I installed the new transducer.  FYI, I replaced the transducer twice on this unit of measurement due to the similar problems.
The transducer is mounted off the transom, port side.  Verbal same location as before (same subclass).
Yes, I accept the old unit and can utilise it to test with � it's just a hassle to rewire, but I'll exercise information technology.

I will try to get on the water one evening this calendar week to obtain a screen shot + examination the other unit.  I will also try various other settings (standard depth finder only, DI merely, surface ataxia, various speeds, moving vs stopped, etc).

I realize electronics can be a hassle (I deal with computers all day in my business organisation) � but this seems like a lot of effort for something that should work out of the box.  Regardless, I'll keep you posted.

Thanks again.

Thank you JohnT.  I but want to make sure information technology is a unit problem (and it is sounding more and more like it is) before you transport in in to exist serviced.

A friend and I spent an hour this evening going over everything: factory default settings, adjusting settings, standard sonar, DI, dual screen, main motor, kicker motor, electric motor, fast, slow, deep water, shallow water, connections, battery charge, etc, etc, etc.

We were looking for some commonality, something obvious that triggers the problem - simply there was nothing consequent.  It would work for a few minutes, and then go bad, then good, and so bad.  Information technology's pretty much useless.

Regrettably I don't have screen shots.  I idea I had captured a few, simply apparently not ... my fault.

And so, to make a long story curt --- I just got off the phone with Cabela's and will render it for a full refund.  I gotta acknowledge I'k pretty disappointed.  For $700 I want something that works out of the box, not 1 that is repaired.

i seem to have the same problem with my 859ci hd di  depth readings .i never noticed information technology till i put my eleven nine 20 transducer on information technology for water ice fishing but may have been there on my gunkhole but did non do also much shallow open up water fishing with it.i have the latest 7.020 software and tried all different settings to clear up the problem of bad readings under 10 ft of water depth .i take set the lower range depth range to the need depth to see the bottom and did not fix it.might get out and get a snapshot today. whatsoever ideas out there

bradleyten,
When you used the XI-9-20 Water ice Ducer with your 859ci Hard disk drive DI unit of measurement; what did you take the Connected Transducer carte set to?
Did you brand this modify before or after connecting up the Xi-ix-twenty Ice Ducer?
Is the DI sonar on your unit of measurement working now?

i pretty certain i tried both the di 200/83 and dual beam settings and sure i tried it earlier and later only non 100% sure due to fact   that i was trying everything i could retrieve of.i did take a snap shot when it was doing it and i notice if i set the depth on the max depth it seem to not bound effectually .i as well brought along my xpth 9 di t that i have and with all setting the same information technology seems to work ok information technology just a little beefy to water ice fish with and also will not stay on my lure due it wont stay level under the ice.allow me know if think of anything to attempt . i fastened the snapshot

bradleyten,
My questions were because of a business that y'all may have damaged the DI circuitry in your 859ci HD DI unit by using a non-DI transducer without first changing the Continued transducer carte du jour.  If the Di is working okay now with the DI transducer y'all should be okay.

When using a non-DI transducer, like the Ice Ducer, yous will need to set the Digital Depth Source carte to the �2D element� card setting.  Effort that and see if information technology works better for yous.

well i know i changed to 2d element per the didactics that came with the eleven nine twenty .exercise non know if i ever change it off of that setting only maybe when i was using it could have gotten alter for just a infinitesimal only it was all the same on second chemical element when i looked at it this evening.   at present i am worried  broke the di  i took it out to a local river with my xpth ix di t and dragged it along the shore line and tried to take a snapshot and did not look skillful .but may not have been moving fast plenty too.i simply wish i would take know it was that sensitive to causing impairment to the unit i would take been allot more than careful or gone a unlike road for ice fishing.just wanted to get the nigh use out of such a nice unit and summers are short here  .what can exist done at this point since information technology simply 6 months old

Glad to finally hear that other people are having the aforementioned problem. I called Humminbird for the aforementioned trouble  and all they told me was to reset the devices. I take 2 859's and they both did that to me towards the latter part of the flavor. I hope somebody comes up with a fix real soon. I would hate to have wasted 1400 dollars on these.

One event with the HB transducers is the critical placement of the transducer with respect to the h2o line. Any aeration around the transducer will cause it to lose signal returns. Sonar does non work in air.
So erratic depths tin be related to the location of the transducer both sitting withal and peculiarly when on running plane.  In that location are a couple of other issues but I would check the location with respect to the speed y'all are running...And ensure that the transducer is not coming out of the water or that another part of the gunkhole is introducing "bubbling" around the transducer...

My transducers are fine as far as placement. This trouble occurs even when continuing all the same in the water.

As long equally the transducer is remaining in the water and not bouncing to a higher place due to waves then your placement might be ok.   Chuck

To add to the list, I accept a 959 that I only bought.  It replaced a 958 so I could use the 360.  I take noticed and emailed HB most is information technology loosing depth in less than xv' of water, it starts jumping all over the place.  Tried all the standard stuff, reset to defaults....  Using the TD that came with the 959.  I am wondering if this is a software issue?  I take max depth fix to 130' which is 10' deeper than my home lake.

well i know i changed to 2d element per the instruction that came with the 11 ix 20 .do not know if i ever change it off of that setting merely maybe when i was using it could have gotten change for just a minute but information technology was still on 2d element when i looked at it tonight.   now i am worried  broke the di  i took it out to a local river with my xpth 9 di t and dragged information technology forth the shore line and tried to accept a snapshot and did not look good .but may not have been moving fast plenty as well.i just wish i would have know it was that sensitive to causing damage to the unit i would have been allot more careful or gone a different route for water ice fishing.just wanted to go the about utilise out of such a nice unit and summers are short hither  .what tin be done at this point since it only 6 months onetime

bradleyten,
Like I stated before: if your DI sonar is working you lot did non impairment anything.  It is not a guaranteed thing that y'all can damage the DI sonar circuitry by using a not-DI transducer without get-go setting the Connected Transducer bill of fare but the possibility of information technology does be and it is something that needs to exist eliminated every bit a possible cause of the erratic depth problems.

Not much to do at this signal if y'all cannot become back out on the water as dragging the transducer forth the shoreline will not produce good tests results.
