Dragonfly update v12.09 still locking on downrigger

[Chuck - Raymarine - Moderator]

Jim,

This is the first such report received in conjunction with Dragonfly displays which have been updated with v12.09 Dragonfly software. Raymarine has not yet announced any further software updates for the Dragonfly displays. That said, the Raymarine MFDs may very well report the depth of downrigger [censored], large concentrations of suspended organics, etc. which produce strong sonar returns. Should this occur and the Dragonfly display then automatically adjust the range to one matching that of the strong sonar return, then manual range adjustment will be required. However, after manually configuring the range to include to permit the bottom to be plotted or a more shallow depth, then the configured range should persist within the display's settings (i.e. the Dragonfly display should not revert to auto ranging). However, it is indeed possible that the Depth databox will report the depth of suspended organics, etc. which produce strong sonar returns.
