OK.........Here's the Humminbird description of what Jigging Mode does in the new 7.460 software for SI units:

On the SI unit Jiggin Mode is a selection in the 2D Sonar Express Menu. It allows the user to select the sonar ping pattern for use while vertical jigging. When turned ON the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, repeat. With this mode turned OFF the ping pattern will be: 200 kHz, Left SI Beam, Right SI Beam, 83 kHz, Left SI Beam, Right SI Beam, repeat. Basically this feature prioritizes the 2D beam over the SI beam.

Here's my summary and some other info from Doug V:


Me....With the Jigging Mode on and HDSI transducer selected, the 2D is given equal priority to SI in the ping sequence.......When Jigging Mode is off and HDSI transducer is selected, the SI is pinged 2 times for every cycle and the 2D is pinged once, giving SI top priority........If Dual Beam is selected, the 2D is the ONLY thing pinged, so 2D is given top priority.


Doug...In Jigging mode it will return the sequence back to the Pre6.6xx performance.


Me.....If anyone has the new software installed please post us some 2D pics with jigging mode on.......Robert got a bunch before his water got hard, but we need to see shots from others to determine if the 2D problems have been resolved.
