Humminbird Helix 5 dual display screens

Hi all, I tried to run a search without any luck.
My boat has a helix 5 SI GPS unit installed and I'd like to run another display screen to the front of the boat for when I'm casting off the front deck. I can spin the head unit on the side console but I'd rather just have a 2nd screen. Is there a way to do this, do I need another finder, how do I go about it??? I've seen boats set up with screens both up front and back, I'm just not sure how to go about it, cheers

the helix 5si is a non networkable unit. so to have one up the front would just mean installing a totally seperate system. if you have an electric trolling motor often people install transducers onto the motor housing to get a sonar reading closer to where they are casting.

Thanks for the reply, I guess I'll go that way then, cheers
