Es128 Chirp down vision issue

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Bill,

The symptoms which you have described are very odd indeed. A screen snapshot would indeed be helpful. Before taking the screen snapshot, I would recommend configuring the MFD to display two fishfinder panes (one configured to display 200kHz sonar from the DSM and the other to display DownVision). I recommend that screen snapshots be taken when operating of flat bottom and that another be taken when operating over structure. Please note that the vessel must be moving at trolling speed to display detailed DownVision imaging.
