Using Fishfinders to Find Swarms of Walleye
The first decision to make is whether you will be using a side pointing model, one that points downward, or a fish finder that offers both with multiple devices on one system.
Side pointed models do not show the bottom structure of the water, and only fish and underwater structures which are off the bottom will appear. many professionals suggest using a fish finder which offers a liquid crystal display unit, instead of the older cathode ray tube models.
LCD displays offer smaller display units and better graphics. Before using the fishfinder to fish with, spend a day on the water without fishing at all. Get comfortable with the fish finder you have purchased, and map out spots where you see good fish activity.
Resolution and contrast are also important, because these will determine how clearly the fish are marked on the display.
Choose a model that offers high pixel numbers both vertically and per square inch. This will allow you to locate fish even when they are grouped close together or located next to underwater structure or the bottom.
Digital displays will allow you to determine the exact depth of the fish, so that you have a good understanding of the depth needed when fishing to get right on the Walleye.
Using a fish finder that has the ability to display the water temperature can also be a great way to locate the Walleye.
These fish prefer cooler waters, and the temperature display will allow you to determine where water temperature is ideal for the Walleye.
This can improve your success rate significantly, just by alerting you to water that may seem ideal for Walleye, but that in reality is too warm in the current conditions.
This feature can have a big impact on locating and catching the Walleye.
It will also help you catch more fish in the future when you log the temperature in your fishing log.
These pieces of equipment can be an important weapon in the arsenal of any Walleye angler, but they do not work very well in shallow waters. This means that fishing along the shore where the water is not deep, such as when the Walleye are spawning, is not the best time to get the most out of a fish finder.
Side pointing models are better than bottom pointing devices in this situation though, because the side pointing units may show the fish suspended in the shallow waters while bottom pointing units will normally not show these fish.
A fish finder will not help you catch more Walleye, but it can help you locate them so that you are more productive and successful while fishing because you are guided right to where the Walleye are.
