As a tournament angler, I’m always looking for ways to utilize my time on the water in the most effective way possible. When prefishing, this means covering the most amount of water as quickly and effectively as possible.
With the technology that is available now, both tournament anglers and weekend warriors can conduct extensive research prior to even leaving the house!
Using online maps, such as Google Earth can provide valuable insight on a specific lake or river. But if you are looking to really dive in a little deeper I would suggest a mapping program that shows the lakes/rivers depth contour lines and other important information—I love Humminbird Contour Elite.
