So I have 4 fish finders, 3 of which have been collected over the years. I decided to upgrade to a new Helix 5 (DI/GPS) unit and now need help making decisions on where to mount them all.

 

Currently, I have a old Lowrance L series (came with boat) and a Humminbird 581i on the console with a Humminbird Piranha on the bow. I also have a mount to move the 581i to the bow, which I have done a few times to mark waypoints while on the trolling motor.

 

My original idea was to take off the Lowrance and mount the new Helix on a swivel mount (i.e. Ram Mount) at the console and move the 581i to the bow permanently. This would allow me to sell the Piranha and Lowrance for some extra cash. Now I am thinking of just using the Helix and getting rid of everything else. Thoughts? I never really grew found of the 581i is that makes a difference.

 

I wonder about interference from pings between them

Why do you need them all?  I have one on the bow, and one at the console.

That is what I was planning on doing but wasn't sure if I should mount the Helix at the bow since that is where I spend most of my time.

Since none of them are linkable to share a transducer, you cannot run all of them at the same time.

 

You can use the 581i for GPS only by turning Sonar OFF and don't have to connect a transducer to it.

Put that beside the Helix and you can have GPS full screen and sonar full screen on the Helix.

 

 Lots use a dual unit setup at the console and bow for the above.
