FishHawk X4D hinky display reading ?

Hello guys, last year no issues whatsoever. First time in the water this year fishing deep 90-110 fow all functions working correctly except inaccurate probe depth readings. Rigger down 90 -105 fow probe is reading only 14 or 17 feet down??? Tried new batteries and increasing the gain but no change!

Could it be electrical interference from you main motor or kicker ?

Would b strange since it operated flawlessly last year. Only variable that changed was we were out in deep water.

Did it work when the probe was shallower?

 

You may need to turn up the gain.  I think the factory setting is 7.  I run at 15 to get good probe performance when fishing deport than 100’.

I tried that but probe depth was still inaccurate. I called FishHawk and the suggested boosting the gain also. If that fails, fill out work order and send probe in for testing.

  Did you change the frequency on your fishfinder to a lower setting for deeper water ? I know my old FishHawk didn't work well with a Humminbird ff the frequencies were to close and gave inaccurate readings. I see the X4D runs on 70kHz ?

Hmmmmmm good point I’ll try that thanks. That would be odd consideration both units worked as they should have last year.
