C-MAP Genesis maps help college fishing winner Isaac Nesbitt find and catch bass

While practicing all day for his college bass fishing tournaments, Clemson’s Isaac Nesbitt records the sonar soundings made by his Lowrance unit’s transducer in order to create highly detailed, custom C-MAP Genesis fishing maps.

After getting off the water after practice, he uploads his sonar recordings — called “sonar logs” — to the C-MAP Genesis website. The upload process is similar to, and as easy as, uploading a photo to Facebook. After his sonar logs have uploaded (it takes an hour or so — long enough to get dinner in the interim), Nesbitt can view custom maps, with one-foot contours, of all the spots he graphed during practice.

Those one-of-a-kind maps showed him subtle, but important, details about the structure around the brush piles that were holding fish — details that do not exist on any other maps Nesbitt has seen of Lake Hartwell, a reservoir he has been fishing regularly for years.

“Other maps aren’t usually perfect, especially with the humps on a lake,” he says. “So you might know humps are there, but a lot of times, a hump on those other maps will just look like a circle — but that’s not really what the hump looks like.”

But because C-MAP Genesis creates custom maps from sonar signals sent out exactly in the places you idle over and/or fish, Nesbitt explains, your Insight Genesis maps will show, with pinpoint precision, the “key points and breaks of humps,” which hold more and bigger fish.

NOTE: “C-MAP Genesis” is now the name of the mapping service previously called “Insight Genesis”
