Helix Mega SI Jigging mode?

What is it used for, or how is it used?

When jigging mode is turned on, it changes the ping sequence in the unit to favor higher priority to the 2D sonar. There should be an improved 2D image but theoretically the SI/DI will be somewhat degraded.

Thanks for the info. I can't imagine what possible use I'd have for that, but then ago I sure don't know much about these things.

It helped improve the 2D with previous models when that was important to people....with the Mega Chirp units it is probably not much of a factor.
