Customer Questions

Does this unit have jigging mode where you can see your lure drop to the fish?

This unit does not have the jigging mode.

Does this have ipilot link

IPilot Link is a Minn Kota feature. It allows you to network the trolling motor to the Humminbird unit. In order to do so you will need to purchase a network capable Humminbird unit, which would be an "N" model. This unit is not network capable. Please click "here" to be redirected to the networkable version of this Helix 7.

What is different between this model (HUM 410950-1) and the (HUM 411080-1)? Please let me know so I could decide on what I am really looking for.

The 411080-1 has network capabilities, and the 410950-1 does not have any network capabilities.
