    AT beam issue

    I have an issue with my AT that has just developed. I've had the unit (Carbon 12) and AT module/transducer for 9 months now and all worked great until recently.

    The issue is when I cast out my bait shows up around 10' deep on the screen right when it hits the water. The distance out seems correct but it's like the beam angle is incorrect. You can actually see a mirrored image of everything along a defined line angling from the boat out. There's also interference which looks like small fish/returns along the mirror line.

    I didn't get any actual pics but here's a simple sketch of the issue.

    Has anyone seen or heard of this before? I'm planning on calling Lowrance Monday.

    My guess is either your transducer is off by one-click up on the mount, stableview is on/off, or an angle offset has been entered in the setup screen.
