Auto chart live two units .

Helix 10 chirp mega SI on console. Can I Auto chart on it and have it do the Helix 12 chirp mega SI on the bow at the same time ?
If so what all adapters/cables etc will be needed ?

You cannot share any mapping of any type with Helix units.

If you want a duplicate ACL of what you do on one unit, you have to copy the files from one Zero Line Card to another and have Zero Line Cards in both.

Thanks Wayne.

Can I put the trolling motor down and auto chart both units simultaneously while idling with the big motor?

[Wayne P.]

Technically yes, BUT you may get a screwed up map due to sonar cross-talk interrupting the depth readout. It takes Depth (sonar) and Location (GPS) to create and position the contour lines.

thanks again I'll try it and see what happens.
was going to spot chart some humps and ledges with my current lakemaster charts to fine tune them.
