Thread: HUmminbird 777c2

Greg,
This week I loaded the old software version onto unit, powered up and switchfire was not on there. So I went out placed on boat powered up for a little bit, came back in and then loaded the newest switchfire version, and it seemed to have loaded correctly.
I went out on local lake today powered up and then switched to using my transom transducer (the one that came with the unit) and NOTHING BUT THE SAME STUFF. same issues I have been having remain despite trying 2 different transducers.Only other thing is the toggle switch that connects the 2 to the unit, but surely the toggle switch wouldnt do it.
I am going to go ahead and by a new transducer for the trolling motor, a dual beam 200/83 instead of using the quad beam sonar as a dual beam, but is there anything I can do to check the unit itself. I am thinking its the unit. can I send it off, anything????????
Please help, im growing frustrated. Im kinda miffed because this thing hasn't been working right the whole time Ive had it..........
I have pics and settings in the other thread "humminbird greg and tommyboyrn"

Tom,
The best way to know for sure where the problem is would be to test your unit on someone else’s boat that has a Humminbird transducer. This can be any of the DualBeam, QuadraBeam or even a Side Imaging unit (but not the 981/987 units).

If you cannot test on someone else’s boat than you should remove the Transducer Switch and plug one of the transducers directly into the unit and test it again to see if you get the same results just to eliminate the switch as a possible source of the problem. If there is a connection issue in the switch it could lead to what looks like reduced sensitivity.

As a last resort you could call the Humminbird Customer Resource folks at 1-800-633-1468 and set it all up to send in your unit and transducers to be tested; but it would be best to try and eliminate what works correctly on your end first if possible.

Thanks greg for your information and time. Im gonna try to do that this weekend.

I took some more pictures with my 778C today. These are dropping a 1/8 oz jig and 1 picture of a 1/2 oz sinker hopping on the bottom. I bumped the sensitivity up to 20 to see the jig.

that looks good shellback!

I purchased a new trolling motor transducer instead of the quad beam. I am gonn put it on without toggle switch then head to lake and snap some pics and will have an update tonight hopefully.

Good luck! Looking forward to the pics.

Ok, well I took the quad-beam sonar off and installed the brand new "out of the box" dual beam trolling motor sonar today. Went to the lake and away I went.........
Settings:
Sensitivity: 17-20
Chart Speed: 9
Lower range: 10-19ft changing as I went to account for different depths
Beam select: 200/83kHz
Maximum water depth: 100ft
83kHz sensitivity:5
Noise filter: medium to high
Surface Clutter: 1
and NO TOGGLE SWITCH

Here are some pics:

So now I am convinced its with the unit, what do you guys think? Send it to humminbird?
Greg, what do I need to tell them about all the things we have tried so far as well as using a completely new transducer?
