Get on top of fish under the ice with Insight Genesis maps
“Insight Genesis is a great tool to help you locate and catch more fish during the hard-water season,” says leading walleye pro Scott Glorvigen. “We’ve got fish on the electronics here and we’ve been catching fish this morning.”
Scott and his twin brother, Marty, are filming a video segment for Wired2Fish on this day. Prior to putting fish on the ice, they spent some time scouting hot spots, driving around on a frozen northern Minnesota lake, studying a custom-made Insight Genesis fishing map on a Lowrance HDS Gen2 sonar/GPS unit mounted above the handlebars of an ATV.
“I’ve got my [Insight Genesis] mapping on that unit and go on the ice just like I would be on open water with my boat,” Scott explains.
Insight Genesis is GoFree’s innovative service that empowers anglers to make custom contour charts of un-mapped and poorly mapped bodies of water, as well as precisely determine, define, dial in, and dissect small spot-on-the-spot areas on well-mapped waters. The one-foot contours on custom Insight Genesis maps are much more detailed and accurate than the computer-estimated contour lines on many digital charts that come on off-the-shelf map chips.

Scott and Marty made their Insight Genesis map of the lake they are fishing on this cold winter day back in the late summer, simply by driving around in their boat and recording sonar data with their Lowrance HDS unit. By uploading that sonar data to an Insight Genesis account, they created a custom fishing map of the lake, complete with one-foot contours, a vegetation-location chart and a bottom-hardness transition chart. They’re using that one-of-a-kind map to find and catch fish today, having saved it to an SD card and loaded the card into the HDS unit mounted on their 4-wheeler.
Prior to making their Insight Genesis map of the lake – one they had fished many times prior – the Glorvigens thought they knew what the lake bottom looked like, Scott says. “But reality is there was a lot of really subtle changes we weren’t aware of,” he acknowledges.
As savvy anglers know, gamefish often congregate on subtle changes on the bottom – slight elevation breaks, isolated weed clumps, and transitions from a hard bottom to a soft bottom. Insight Genesis is the only DIY mapping program that empowers anglers to find, map and fish all three via a cloud-based program that allows you to also download other anglers’ shared maps of lakes you fish and keep all your map data secret and private, if you choose to.
The Insight Genesis bottom-hardness chart – an optional map layer that can be turned on or off while fishing – helps the Glorvigens find and catch many fish on this day on the ice. By locating the dark-orange-colored areas on their Insight Genesis bottom-hardness map, they can drive to, drill and drop baits at areas where the lake bottom transitions from a hard to soft bottom.
“Those areas are typically very key as fish-holding spots in the wintertime,” Scott explains. “A lot of times, that is where the zooplankton rises off the bottom and that’s where the panfish really congregate.”
The Insight Genesis bottom-hardness map also helps the Glorvigens develop and work a pattern. If, for example, they’ve been catching good fish off of a hard-bottom point that extends into deeper water, but that bite there shuts down, they can “simply look for that same type of transition and move to that area,” Scott explains. “Once I establish a pattern and the fish are set up on a particular spot, I can simply look at that custom map and duplicate the area I’m on.”
The Glorvigens use their 4-wheeler track to “draw” a trail in the snow along bottom-hardness transition lines. They then drill holes along those trails and walk them, dropping the transducer of a handheld fish-finder down each hole, looking for fish. Where they see fish on their screens, they drop baits and catch ‘em.
Insight Genesis Social Map
If, unlike the Glorvigens, you didn’t map your favorite ice-fishing lake this summer or fall, check Insight Genesis Social Map for a community-sourced custom chart you can download to an SD card and use on the ice in your Lowrance HDS or Elite sonar/GPS unit. Your favorite fishing hole might have already been mapped by other community minded anglers.
Insight Genesis Social Map is an online database of custom contour maps generated and shared by community-minded anglers and boaters in the Lowrance community. With Social Map, you can quickly and effortlessly get detailed contour maps of thousands of water bodies, including those close to home, across the country, and around the globe. Built on a base layer of existing Insight contour charts, Insight Genesis Social Map refreshes itself in near real-time with current sonar data shared by the Insight Genesis community, revealing new fishing holes for anglers in never-before-seen detail.
