Without GPS, you’d rely on landmarks or dead reckoning, which can be inaccurate and unreliable.
Beyond basic navigation, GPS integration enables features like contour mapping, which displays depth contours on the screen, helping you identify underwater structure and drop-offs. You can also save sonar screenshots with GPS coordinates, allowing you to revisit those locations later and compare sonar readings over time. Modern fish finders often allow you to share waypoints and routes with other devices or anglers, enhancing collaboration and information sharing.
How much power (watts RMS) does a fish finder need?
The power of a fish finder, measured in watts RMS (Root Mean Square), determines its range and ability to penetrate deeper water. For shallow water fishing (under 100 feet), a fish finder with 100-200 watts RMS is generally sufficient. However, for deeper water fishing (100-1000+ feet) or fishing in murky water, you’ll need a more powerful unit, typically 300-500 watts RMS or even higher.
It’s important to note that watts RMS isn’t the only factor; transducer quality and frequency also play a significant role. A higher-quality transducer will transmit and receive sonar signals more efficiently, even with lower power. However, generally, more power equates to better performance in challenging conditions. Consider the typical depths you fish and the water clarity when choosing a fish finder’s power output. A 2018 study by Boating Magazine showed that increasing power from 200W to 500W improved sonar penetration in murky water by approximately 30%.
