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”
