Thread: New fish finder

Maybe this will help with imaging

Down Imaging vs. Side Imaging on Fish Finder (Plus Tips and Tricks)

I would get a MEGA DI unit which will also have SI. A SI unit will not have DI. You can alway call Brian at BBG Marine (Member Sponsor)l he is very knowledgeable and will answer your questions and concerns.

Might want to think bout the largest screen you can afford. My ole eyes needed a 10 inch screen.


Rickie aka rnvinc may chime in one here as we..

I know it is the wrong time of year but I would love to ride along and see how you use your electronics.

Great time of year for fishing or scouting if you can stand the cold

Think you have it backwards. Si has di. Do doesn't have so.

While it’s true that HELIX 7 SI does have DI - it’s not dedicated DI with a true “downward pointing” piezo ... all HELIX 7 SI units have a computer generated DI image generated from the data received from the “side pointing” SI piezoes ... (I can explain this further in a separate post or PM if anyone needs more clarification) ...

One would need to step up to the 8” units (or larger) to get true dedicated DI in the HB SI line ...
——-

Also ... any HELIX unit must have “N” in the model name to network (G3N or G4N) ... (HELIX 7 is also offered in G3 and G4 that does not Network - cost saving HB offer for those that don’t need networking ) ...

“Networking” (in the Humminbird speak) is generally focused toward “which Sonar technologies” can be shared thru Ethernet or “can waypoints be shared” thru Ethernet ...
——-

Minn Kota US2 built in xducer is not compatible with HELIX G3N or G4N because US2 is 83kHz/200kHz 2d Sonar and HELIX G3N and G4N utilize CHIRP HW Low Q 2d Sonar ...

Note: US2 only pertains to the built-in 2d xducer in the Minn Kota TM ... iLink is a completely separate feature offered that allows some TM control functions from the HB head unit thru Ethernet ...

Secret: This is possible because Johnson Outdoors owns both Humminbird and Minn Kota (and other brands) ...

Thanks for the replies!! Can I run two different head units off of one transducer with a splitter? Like a helix 5 and a helix 7 and if so do they have to be the same generation?

I want it for when we are side drifting my wife can watch the big one at the helm from the back of the boat and I can watch a smaller one in the front so I can keep an eye on the depth and fish.

Or can I run 2 different transducers at the same time? The trolling motor and the main one at the stern of the boat.

Sorry if I am confusing everyone because I am confusing myself. Lol

I’d go for 2 transducers if it were me.

Setting 2 head units to view data from one xducer is called “Networking” and is achieved with Ethernet capable units and Ethernet parts/cables ...

Unfortunately no HELIX 5 units are network-able for Ethernet ...

And only HELIX 7 units with “N” in the model name are Network-able for Ethernet ... (i.e. HELIX 7 G3N or HELIX G4N) ...
——-

NOTE: All HELIX 8” and larger are Network-able with Ethernet ...

There is no current configuration in HB that allows one head unit to view 2 separate xducers ... (except in the rare scenario that a user needs to separate a 2d signal from a SI xducer for high speed depth readings - or the rare scenario that a user needs to have a left SI on the port side of the transom and right SI on the starboard side of the transom) ...
——-

Now ... running 2 separate xducers on 2 separate head units is possible - with the caveat that “crosstalk” interference (between 2 separate xducers pinging the same frequency(s) at the same time) is possible...

“Crosstalk interference shows up as unusual dots/lines/bars/fuzziness —->> and can be verified as “crosstalk” interference by shutting off one head unit - if the interference goes away = its “crosstalk” and just an inherent artifact of pinging 2 “like” Sonar frequencies into the water at the same time ...
