Humminbird users?

I bought a new 688 ci hd di last year. it will show the bottom but there is never any thing else on stick ups trees fish or any thing . I figure it is probably me any help sure would be great

Can you post pix of your xducer installation ...??

Have you tried Restore Defaults under the Setup tab ... ??

Rickie

I'll take a pic tomorrow and no I haven't restored defaults

Here is how I have it mounted

Make sure the xducer is level with the TM housing ...

Then try the Restore Defaults ...

Restore Defaults will put the unit settings back to factory settings which should give some kind of return ...

Then of course ... Test on the water ... Sonar doesnt work thru air ...

I have noticed that the ducer will move some no matter how tight the screw is. will that have affect on it?

The xducer not being level will have some effect ...but not to the point of your issue not showing any returns ...

If Restoring Defaults doesn't work ... We will have to troubleshoot further ...

I have noticed on the down imaging screens of my side imaging units, I need to run the sensitivity almost maxed out. Don't know if it will be the same on the dedicated side imaging units.

Thanks for the help guys

Took my boat out to try my fish finder after restore defaults. don't know what the pictures are but it did show something this time
