I recently upgraded my transducer to the HD transducer and it made a huge difference but I was having some issues with the unit not returning a signal for the bottom past 13' for some reason.  So on the water today I reset all factor settings and everything was great except i could no longer use my cursor while on any of the DI/SI/Sonar screens.  It worked fine on the settings, menu etc...but not when viewing the images.  It worked prior to my reset so I am assuming there is some setting i messed up when i was setting up which screens i wanted to see etc...

This is mounted on a kayak as well if that matters.

Is your battery fully charged?

Do another Restore Defaults.

Yeah just charged it last night and everything looked good.  I'll try another factory reset when i go out tomorrow.
