Humminbird mega questions

[bigbasshunter]

Im a lowrance guy but this new mega chirp si, is looking very nice. Looking at getting a pair of Helix 10s to sit side by side at the console. How does transducer sharing work? Can I use one mega SI ducer and have the units share it, I want the left unit to show only left SI and the right unit to show only right SI? Do both units need to be mega g2n? Any and all help is greatly appreciated

I'm no expert, but I think that the answer is that if you have the right ethernet wiring connecting the units you can share the transducer and then select the view separately for each unit.  

 

Just a guess, but you rob banks for a living, right?

Anyone know where Wayne went?  I hope he just moved and didn't have other problems.  I learned more from him than from Humminbird.

No expert, but here's what I know.  You need to use a y cable at the end of your transducer cable and plug each end into your units. Both units need to be mega. A regular helix will not read off the mega transducer.

I've seen him on another forum so everything's ok from what I can tell.

I have a mega Helix 9 at the helm and a Helix 7 at the front.  The 7 is not a mega.  It reads the mega transducer, but not at the high resolution that the 9 mega does.  They are connected with an ethernet cable.  I don't think it is a "Y" cable.  The communication is done through the ethernet cable.

I "think" the Y-cable is used if you want to use 2 transducers like a thru hull transducer.

Humminbird recommends a Y cable and a second transducer when users have trouble getting the mega transducer to properly display depth at speeds over about 5 mph.  Supposedly the unit uses the mega transducer signal at low speeds and the other transducer signal when the speeds are higher.  I don't know how that happens, and don't even know that it does, but Humm says so.  The mega can be properly placed, depth and angle, to read properly at all speeds, but it is not easy to accomplish.  I'm talking attached transducers, not through the hull.  More detail can be found on Humm customer service, search for depth at speed or some term using speed.

If you network them ,

Ethernet hub you can share. I can see my troller transducer or the 360 on either unit . I have 2 ,12 mega units on my boat

Both units don't need to be MEGA.  I can see SI on my DI front unit.

 

Both units need to be G2N.

 

I don't understand the reason for spending 2x to set one unit to right and the other to left...and then trying to save money by only hanging one transducer.

 

There is plenty of detail on one 12" Helix screen. ..or one 15" Solix screen @ 1.2 MHz...

 

...but if I wanted to do this, the best way, no question about it, would be to place one transducer on each side of the outboard motor.
