GPS Inserts are cards of data that show a detailed mapping of an area of water

Gps Inserts Help Anglers Find Fish

GPS Inserts is a technological match made in Walleye fishing paradise thumbnail-size data cards including the depth contours of the water you are fishing that may be added into GPS units. Similar in size as well as layout to the memory chips for digital cameras, the multimedia cards show the lake’s bottom in your GPS plotter screen. Such onboard info lets you troll with precise precision over and about the critical humps, points, and turns where Walleyes congregate.

Drawing upon exceptionally exact National Oceanic and Atmospheric Administration source data, depth processors with hydrographic contours make for safe navigation in addition to exact trolling. Picture an onscreen map rather than a paper chart, with your boat’s location revealed in regard to what is underwater as well as its location in the world. That makes it possible to take evasive maneuvers around a stone stack and to keep the boat along with your lines just where you would like them.

Nipping and Zooming Where you go for a troll on large water ought to be a function of the elements revealed on a hydrographic map. Likely holding places for Walleye are readily identifiable in the type of stone stacks, points, and submerged contours the fish travel like highways. The edge of electronic mapping, however, is that with it you can head right for such places rather than roaming about looking for them, attempting to fit what you see in your depth finder with the contours on a paper map.

Since Great Lakes walleyes hold off the border of distinctive humps and lumps instead of directly atop them, a great plan would be to set up a troll that nips off the borders and covers the gaps between submerged promontories, where the fish hang to feed on baitfish.

Another approach will be to maintain the boat trolling in a specified depth say, 25 feet and follow the twists and turns of the contour line on a pass up to a number of miles long. When you get a fish, zoom in to pay attention to any points on the contour, then zoom back out to see what is forward and whether any similar places at exactly the same depth are on an identical contour, even if they are miles away.

But not all the humps and points are clear. When the prevalent depth stays similar, possibly at 30 feet, every once in awhile you will notice a small change indicated not with the contour line but with amounts 27 feet, as an example. Although the small rise isn’t sufficient to justify a full fledged hump on the electronic map, the minimal change in depth is worth a deviation in your trolling pass to pull across it.

Who Makes GPS Inserts

Bottom Line, Humminbird, and Sitex are among the GPS brands that choose cards produced by Cmap. Some processors include broad swaths of water, including much of the Great Lakes. The cards price from $99 to $199.

One of the alternatives on Navionics processors are NOAA graphs of parts of the Great Lakes and some linking waters enriched with an organization database that enables you to zoom without overlapping text and falling upon blank spaces. Additionally available are electronic versions of fishing hotspot maps, called HotMaps, for 14 areas ($129 each), including a wide selection of waters. It’s possible for you to see in case your favourite lake is one of them on the Navionics site. Their maps might be utilized with Furuno, Lowrance, Raymarine, Sitex, and other units.

Fish Finders GPS Inserts

Based on tech support at Lowrance, establish the update speed of the GPS unit at its most rapid, once per second, to give the most regular info from the satellites. When trolling, you need to reach the closest thing to immediate upgrade to be able to get the most precise readings of your situation and also make corrections without delay. The technology hasn’t been so great, along with the walleyes have not been so nervous.

Discover Fish Quickly

Fish locators with integrated mapping abilities are revolutionizing fishing strategy. Case in point: the Lowrance X-104C fish locator, with its tremendous display (10.4 diagonal inches) and its ability to run in split screen mode, with GPS mapping on one side, fishfinder on the other. It’s possible for you to organize a trolling pass on a contour line while simultaneously observing the locator for fish.

With the colour readout, the most spectacular improvement is the capability to see orange and reddish hooks of hanging fish at high running speeds (25-30 miles per hour) in open water that will otherwise go undetected in black-and-white surface clutter. Turn “ping” speed and graph speed to max, get on airplane, punch in a waypoint when you find fish, and go back and mop up.
