Humminbird 899

Every once and a while my 899 depth will be very wrong. It will say I'm in several hundred feet of water when it's not nearly that deep. I have attached a picture to show what I mean. Any ideas on what's goin on here?

I get that when I am too shallow for it to work properly? How deep of water were you in?

It does it even when I'm out deeper in like 20 feet. Not just when I'm shallow. I was prob in 6-8 feet during this picture

Do you have another Humminbird on the boat? Sometimes two units running on the same or a very similar frequency will interfere with each other, causing incorrect depth readings.

Ya. I have an 859 up front. However. If the frequencies cause interferences wouldnt I have the same problem up front?? Because the front unit has never done this. Except in very shallow water.

Not necessarily. Try turning the front unit off for a while and see if you still experience the same problems.
Right now this is a process of elimination. So try one thing at a time to see if you get any results.

Yep I was going to mention that too, I have to keep my front and back set to different frequencies just for that reason.

I didn't know the frequency could be changed.
@JackJ how do you change the frequency?

On my Elite 5, I can chose between 50khz, 83khz and 200khz, and the downscan works at 455khz.
On my HDS 7 I can chose even more, but I usually leave it on sideimaging most of the time anyways which works at 800khz.
In the menu you chose, sonar> then Frequency, then just change it there.
Surely you can do this on the humminbird also.
