Is navionics sonar charts compatible with hummingbird units?  It lists a few lowrance sonar units but no hummingbirds that I saw.  Looks like a great way to make accurate, detailed maps.

Yes

 

Sonar Charts Live is not. That is a new feature added to some current Lowrance units.

 

Humminbirds will read the Sonar Charts maps on a map card.

Thanks for the reply's.  

So the hummingbirds can't create the hi definition maps?

Yes they can.

Humminbird has the Auto Chart Live feature with some models. I have three units that do that. The created maps function like Lakemaster maps.

 

To create Sonar Charts maps, you can record sonar logs and upload them to the Navionics Sonar Charts server, Navionics processes the data to create the Sonar Charts HD maps, then you download them to you Navionics map card. I have been doing that since the Sonar Charts program was activated in the U.S.

 

Lowrance just started with the Sonar Charts Live so they could have a real time mapping function like Humminbird and Garmin has.

 

The colored areas here is Auto Chart Live overlayed on a Sonar Charts map I collected data for:

 

This is a pond dam with Auto Chart Live that I did when testing a new unit. It is overlayed on the Humminbird base map Uni-map.

The model I would be using (I don't own it, but I'm doing some research for a family member) is the older model of the helix 7 si/di GPS, and I don't think that model has the live sonar charts I believe.  Thanks for the reply's.

That model does not have a real time HD mapping feature.

The first generation Helix models of Helix 9, Helix 10 and Helix 12 have Auto Chart Live.

 

The G2 and G2N versions of all Helix units have Auto Chart Live. The pond dam above was done with the Helix 7 CHIRP SI GPS G2.

 

With that unit you can record sonar logs (RECORD function) and have Navionics create the HD maps.

BUT for accurate contour maps you must have a GPS antenna where the sonar transducer is.

Contours are created from the depth readout and are positioned by GPS.

Thank you, he was mostly looking at the navionics for the auto charts function, so I think it might be money better spent on saving up for a helix g2.
