[CA] Axiom 9 RV seeing down-rigger weight

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum 1851DC,

It's quite unusual to receive a report from a Dragonfly customer who was unable to see sonar imaging which included downriggers (assuming that they were deep enough to be within the cone of the CHIRP conical or DownVision sonar). In contrast to this report, one of our most common complaints with early Dragonfly software was that the Dragonfly display's auto ranging feature was locking up downrigger [censored]. I would be more inclined to suspect that the lack of sensitivity was indicative an incorrect configuration setting (i.e. not operating in Auto and then reducing the sensitivity levels) or of a problem with the Dragonfly display or its transducer. You may want to consider trying to set the sensitivity settings to auto or increasing the sensitivity settings of your Dragonfly display to address this issue.

That said, one should quite readily expect that an Axiom RV MFD or Axiom Pro RVX MFD with a RV transducer will detect downrigger [censored] if they are within the cone angle of the selected sonar source.
