I have recently purchased a Humminbird 788ci and then bought the Navionics chip for it. It does show tides for the delta, but only in a few places. You have to look for a "T" inside a diamond shape, move the cursor to that symbol, and then just press the info button. Using the "left" and "right" cursor keys, you can also move forward and back a day at a time. I have attached a couple of screen shots from my 'bird. I have not seen any tide info for the lakes that I have checked out, but then I didn't really expect any.
I was wondering if the Navionics chips will display the tides for the Delta on lake and rivers or is that only on the salt water chips. Thanks for any info.
