? Humminbird Greg

[Shellback]

My buddy just picked up a new 788C, but his boat is laid up for winter. I told him to bring it along on our next fishing trip and we can plug it into my 778C mount to try it out. The 788C has an external GPS antenna, which he won't be bringing along. I have my 778C linked to my Garmin 498C with the Humminbird cable. Would there be any harm to the 788C by getting input from the Garmin, rather than the H/B external antenna? Or should I shut off the NEMA output on the Garmin before powering up the 788C?

No there should not be a problem with this Shellback.
However he could just bring his GPS Receiver along and lay it on the deck if he wants to test it out too.

Shellback~If you all don't mind please post on how this unit works. I have the 788ci and still trying to get the kinks out.
Thanks!
Losing the bottom reading off and on. Have tried numerous settings and ended up pointing the transducer ahead a bit just to keep a depth reading.

Hopefully we will get out on Thursday and I'll let you know how it works.
