Mile-high mapper finds what’s missing on many map chips

Kooser Side-by-Side
Which map would YOU rather use for fishing? These images are from maps of the same spot on the same lake. Insight Genesis created the great map on the right.

Many fishing maps for off-the-beaten-path lakes merely mimic old USGS topo maps and lack detail – a challenge that used to frustrate Dave Kooser, who fishes for walleye and bass in Colorado, a state known more for ski slopes than fishing holes.

“Map detail is even less accurate if the body of water has been around for many years, as topo maps were less accurate in the early years and things change underwater through time,” says Kooser, a Colorado TBF member and former Colorado Walleye Association President.

But Kooser isn’t wasting time waiting for a survey crew to stumble upon his favorite lake, he’s mapping it himself with Insight Genesis, the cloud-based service exclusive to the Lowrance community. And he’s finding great fish-holding structure that’s missing on many of the off-the-shelf map chips.

What Kooser has learned with Insight Genesis will likely shatter some anglers’ perceptions of the usefulness of many off-the-shelf map chips – especially for lakes not actually surveyed with sonar.

“Insight Genesis has confirmed that perception is not reality,” Kooser says. “Factory-loaded maps are perception, Insight Genesis provides reality.” (To learn more about why many of your fishing maps are not as good as you think they are, read the article at this link.)

Check out the screenshots below to see for yourself. The first is a “Before” picture of a section of an off-the-shelf chip map of Kooser’s favorite lake in Colorado. The “After” photo below shows the same section of the same lake, as mapped by Insight Genesis.Kooser BEFORE image

I can also find other areas like this that I have never fished before and give those a shot. “Try doing that with the “Before” maps in most of our units.”

The maps on many chips are just not much help to anglers looking for a specific depth, weedline edge or bottom composition, Kooser says. “Sure, you can launch your boat and hunt and peck for what you are looking for, but staying on the necessary depth or weedline edge gets to be a challenge if your boat moves,” he says. But with a custom-made Insight Genesis map loaded onto his Lowrance unit, Kooser can drive right to a potential hot spot, cutting way down on scouting time and greatly increasing fishing time. His Genesis map helps him learn from his success as well.

“The map can now be overlaid on top of previous waypoints, giving some explanation as to why the fish might have been in that location,” he explains.

Better maps. Better fishing. It’s that simple.

Better get Insight Genesis.
