It is true sonar, GPS and now side image revolutionized the fishing industry. As a Professional Bass Angler I could not compete competitively without it. Knowing how to use and read the unit takes a little practice, but it has made my job 100% easier and allows me to stay in the “effective zone”.
I use the GPS portion coupled with a navionics mapping chip to ease navigation and find offshore structure. Having this information at my fingertips cuts my practice search time and provides additional opportunities to locate fish and piece together a productive pattern.
