Topic: Scratches on the Transducer

[offroad]

Do they affect the unit ?  They are not deep, just a few across the bottom. Why do l ask ? Well my 898 is having trouble reading the water depth. Its constantly changing.   The screen contines to change.Now before you ask...l have changed nothing. This happens on all the Sonar screens .Yes  including SI......The only thing is the scratches

If you are in shallow water (less than 5 ft)....then your depth reading problem is shared by many HB users....

This seems to be a software problem that HB is working on..

Hopefully HB will have a software fix for this soon...

rnvinc is correct.  I too have the same problem with shallow water depth on my 898.  I run the dual ducers as well.

I hope Humminbird can come up with a fix on this and maybe even a deal to brighten the screens just a tad.

Over...love, love the unit.

Guys
        Thankyou for your replys but alas its in any depth of water.  The setting that l have it on is Auto

Hi,

It's probably not the scratches. I have lots of scratches on the transducer I use with my towfish. I have pulled the transducer over mud, gravel and even rocks and got some nasty scars, but no effect on the image. The auto setting of depth can sometimes jump up and down because of many reasons. I have seen my unit lock on the thermocline, layers of algea and dense clouds of baitfish. The unit does it's best, but the reality down there can, sometimes, fool the smartest depth finding algorithm. A way out is to set depth range manually and read depth from the image (and hope you are smarter than the unit), not the figures.

            Thankyou for your reply. That seems to take that out of the equation its just that the unit was working fine last week .Maybe its a case of different water conditions. l will try and use the manual settings .Stay tuned !
