Fish Finder issue

[pikeguy]

I'm having problems withe my sonar, Its a humminbird 565 dual beam. When i'm trolling it jumps around in the depth it will go from 28 fow to .8 and stay there sometimes if i reach down and put my hand under the traducer and it comes back. Other times it wont and it stays at .8 fow even if i'm in deep water.

 

I followed the instructions on were to place the transducer

 

Any help on this or if someone else had this problem or still does.

I was having that problem on my 587ci so i reset to factory specs, and the problem seemed to disappear.It may be because i played around too much with the settings, and it put it out of wack.

Generally an air bubble under the transducer does that G. Try lowering it a tad... or clicking it down a notch on the angle adjust.

i have tried that Wane tried down and tried up and still did nothing for me.

 

I' m hopping to get a few ideas to try this weekend. hopping the weather is on my side that is

Does it happen all the time or only when you are going a decent speed??

Sounds like a faulty transducer,

can you check your head unit on a buddy's boat with the same setup?

Its a humminbird

 

there's your problem

 

if it has a setting for reducing surface clutter, try that.

Minor adjustment is all thats needed...
