Axiom not marking fish

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Jim,

The RealVision3D and DownVision features excel in locating and providing detailed images of structure. As with other products supporting High CHIRP (conical) / DownVision fishfinder sonar (ex. ax8/eSx8 MFDs, CP100), it is recommended that the HIGH CHIRP (conical) fishfinder sonar channel be used when seeking to mark fish. Are you using the HIGH CHIRP (conical) fishfinder sonar channel or have you been primarily using the RealVision3D fishfinder sonar when seeking to mark fish?

We haven't received any similar reported of the bottom loss and interference reported. I would recommend continuing to monitor the Axiom MFD's performance and also await the next Axiom MFD software update. This software update will include enhancements to the product's fishfinder features which may address the reported issue.
