Okay, so I've got a new Terrova on the way with IPilot Link and the built-in Mega Down Imaging Transducer

I will be ordering a Helix 7 G3N with the Mega DI and IPilot Link capability.

What do I need to buy in order to run the unit up front when spider rigging, and also be able to move the unit to the rear for use when trolling cranks?

Is there a "Y" cable that allows me to run a cord to the front and rear for the same transducer?
