First off your finder has to be compatible, my lower model sonar phone doesn't have the capability, but the one with a transducer that mounts to my boat does do this. I have to pull up the Navionics ap and use it (needs to be active while your scanning the area) and the fish finder ap on it and it sends all the data to the main data base. You don't have to do anything special besides that... But to get good data, you need to crisscross an area, so you get accurate depths to pass back to the mapping software... I used this in the top end of Hyrum and it mapped out the old river channel coming into the reservoir and so on the ice I was able to go sit on the tops of the old channel banks and it was really a very active spot... Wish I could show you how it works, it's easier to see than explain... Later Jeff
