The Simrad GO7 is a unique, and in some circumstances, superior choice to the typical fish finders on the market. It’s designed as a navigation system first, and it currently blows everything else out of the water. Luckily, it has sonar functionality tacked on. Is it the best on the market? Not even close. It’s comparable to some of the more simpler models, and can compete in the mid to high range with additional sensors. For this reason, we highly recommend it if navigation is important. It would also make a fantastic addition to your existing fish finder system. But if you’re not too concerned about navigation, then you might not find as much value in the system.
