Could someone familiar with the Humminbird 797C2 SI Fishfinder GPS Combo tell me if this side imaging is as good as reported?

The included Navionics Gold and HotMaps Premium--is that inland waterways or does it include marine charts as well? I cannot tell from the description or from the Navionics web site.

Any help would be appreciated.

I found this information about Side Imaging to be interesting:

Seems quite interesting for sure.
Wish they explained what was included with the "Gold" and "Premium" software.
It's an extra $2000

NMEA 2000 compliance would be a nice addition.

Correction: $200

I had a particular target for this sort of unit, but we finally
managed to relocate it without high tech help. I think that
for what I do, I'd go with a multibeam unit so I can see
what's under the boat: Humminbird Matrix 47 3D or 967 3D.
I've got a six-beam Humminbird, and there's a bad connection
somewhere (it shuts off every time the boat comes down hard),
and 11 beams would be nice.

Now, if you want to identify what that structure down there
is, the side scan would be the way to go.

The side imaging works very well down to close to 130 feet or even 150 feet. The newer unit has a slightly larger screen and a movie clip mode rather than just the snap shot mode. There is also optional built in Navionics maps for an extra price that sounds like a great deal for the traveling boater.

It will not provide crystal clear perfect picutres. Some conditions produce better images than others--the bottom line is that the machine works as advertized and as a diver it is very useful for locating and exploring for dive sites, huge map area with Navionics charts loaded, lots of features.

There is also an improved transducer shape I think as well though I can hold bottom lock in the excellent standard sonar mode to well over 35 MPH but it does kick up some spray.

I go mine on an early close out, good price, the new unit has some solid improvements, nothing major but still improvements.

My wife has been able to image me diving below the boat at about 30 feet.
