Chart Manual Mode??

[BobT]

I found a feature on my Lowrance X67c. From the sonar menu I scroll down to select "Sonar Features." There's a "Chart Manual Mode" checkbox in there that I don't understand and there's nothing in the manual about it. I can turn off Auto Sensitivity and Auto Depth Range and manually set these without checking the "Chart Manual Mode" option. So what's the difference? 

 

Anyone have a good explanation for this and how it can be beneficial?

It's been a few years but I think it's when someone wants to only see a part of the water column like if they are fishing in deeper water looking for suspended fish at a certain depth zone or fishing just on the top or just all the bottom and don't want to keep seeing the screen and depth range numbers keep jump back and forth on Auto?

I am able to shut off the auto depth range and manually set it to whatever maximum depth I want. It'll stay that way until I reactivate auto depth range. For example, if I manually set the depth range to 60' it will lock the scale to 60' regardless of the actual depth. I can do this without checking the "Chart Manual Mode" box. 

 

I found plenty of examples in an online search where it is recommended to check the "Chart Manual Mode" box but not one explanation why this is to be done or how this checkbox changes things. I sent the question to Lowrance yesterday but still waiting for reply.

Ya, I was saying more of you can set a zone of either, bottom, middle or top of water more like a Zoom. Not the whole depth zone top to bottom.

Hmmm. Will have to experiment. I don't know if I've ever found a way to do that except with the zoom bar feature.

For anyone else that may have wondered about this I did get an answer from Lowrance. Essentially, it disables auto depth range, auto sensitivity, and fish ID all at once leaving these things in full control of the user.
