Pines Mapping Question

I have a Lowrance HDS 12 Carbon unit and would like to get a mapping chip that has the main channel marked. I was told by a guy that the older Navionics chips had the channel marked but the newer ones don't. Is this true?

Are there any chips I can buy that have the channel marked correctly?

It depends on what you mean by marked. The depth of the channel is good on the newer Navionics Platinum chips. They have an overlay option that makes a good 3-D view of the deeper channels and you can trace from there. But, if you are looking for a line down the middle I can't help you, I haven't seen that in a while.

Yeah, that's probably what the OP "Needs" You went to navigation, I went to finding fishing spots.

OP: if you do use Navionics for the main river channel, don't expect you can run it, even if it is mapped the way you want it to be.

I'm just wanting one that shows me where the channel is accurately for fishing purposes. Whatever is on my unit now isn't close. Thanks.

This is correct, I'm running Carbon 12 with the new navionics u.s. south platinum card and the overlay option is pretty accurate.

Keep in mind that the channel of a 60+ year old lake can be silted in in places.
