I thought I saw a portable unit that had a feature that allowed for map generation of uncharted waters. I see the FishHunter has this function but the resolution quality looked poor. The Insight Genesis software looks great but maybe not useful with portable units -esp with smartphone use?

What's out there? Anything?

As far as for use with a smartphone, navionics has sonar chart live, but you still need the locator to get the info from if I understand correctly. Humminbird Onix is able to create live charts on it's own.

The Vexilar Sonarphone is a wireless transducer that gets its display via WiFi to a smartphone or tablet. There are three Sonarphone versions. One is a castable bobber transducer T100, and the other two are boat mounted with power supplied either by the boat T200 or its own battery T300. Only the boat mounted versions will do the mobile device pairing for Sonar Charts Live. 

Navionics paired with Vexilar to have Sonar Charts Live on the mobile device. The system creates depth contours in real time that are written and stored in the mobile devices memory. Additionally when the device is in a WiFi area, that data is automatically uploaded to the Navionics server to be added to the Navionics Sonar Charts shared mapping after processing that can be viewed on their Web App, downloaded to a Navionics maps card with Sonar Charts capability, and is also added to the Navionics Mobile App maps.

The Sonar Charts Live sonar source can be via WiFi from a Lowrance unit, and a couple of other sonar unit brands. Still viewed and processed by the Navionics Mobile App.

I use the Vexilar Sonarphone/Navionics Sonar Charts Live setup.

I also use the Humminbird Lakemaster Auto Charts Live with my ONIX. The new Humminbird Helix models in the 9, 10, and 12 series have the built-in Auto Charts Live feature too.

OK, thanks guys.

These two maps are the same lake that I had done via the Navionics Sonar Charts program using sonar logs from my core Humminbird units.
