Overview of the Products
The Lowrance Eagle Eye 9 Live Sonar FishFinder/Chartplotter is priced at $999.00, while the Lowrance HDS PRO 12 FishFinder/Chartplotter costs $3,099.00, making the Eagle Eye 9 about 67% cheaper. Both products are designed for fishing enthusiasts, but they cater to different needs and budgets. While the Eagle Eye 9 is an accessible option for anglers seeking live sonar capabilities, the HDS PRO 12 offers advanced features and larger display for serious fishing expeditions.
Display Quality
The Lowrance HDS PRO 12 boasts a 12-inch SolarMAX HD touchscreen, delivering crisp visuals and superior clarity in various lighting conditions. This display is designed to be viewable at extreme angles, making it ideal for bright sunny days on the water. On the other hand, the Eagle Eye 9 features a 9-inch IPS display, which, while clear and sunlight-friendly, does not match the size or advanced technology of the HDS PRO 12. Thus, if a larger display with enhanced visibility is crucial for your fishing experience, the HDS PRO 12 is the clear winner here.
Sonar Capabilities
In terms of sonar technology, the Eagle Eye 9 offers a versatile four-sonar mode system, including Live Forward, Live Down, CHIRP Sonar, and DownScan Imaging. This allows anglers to gain real-time insights into fish behavior and underwater structures. Conversely, the HDS PRO 12 is equipped with the ActiveImaging HD transducer, which supports ultra-high-definition CHIRP, SideScan, and DownScan Imaging. The addition of ActiveTarget 2 Live Sonar readiness further elevates the HDS PRO 12's capabilities, enabling anglers to observe fish reactions to lures in real time. Therefore, for those prioritizing advanced sonar features, the HDS PRO 12 is the more powerful choice.
Chart Options
Both models come with preloaded charts, but their coverage and detail differ significantly. The Eagle Eye 9 includes C-MAP Inland charts covering over 17,000 U.S. lakes and offers the innovative Genesis Live feature for custom contour mapping. In contrast, the HDS PRO 12 is preloaded with C-MAP DISCOVER OnBoard charts that provide 1-foot contours on over 19,000 U.S. lakes and 9,400 Canadian lakes. This greater detail in mapping makes the HDS PRO 12 a superior option for anglers needing precise navigation and fishing spots identification.
Installation and Usability
The Eagle Eye 9 is designed with a reliable twist-lock connector system, making installation straightforward and hassle-free. It is marketed as highly accessible, appealing to anglers looking for a user-friendly experience. The HDS PRO 12, while also user-friendly, offers extensive integration options through built-in NMEA 2000, wireless, and Bluetooth connectivity. This allows seamless integration with various fishing technologies, but it may involve a more complex installation process. For those who prefer simplicity, the Eagle Eye 9 might be more appealing.
Price Comparison
With the Eagle Eye 9 priced at $999.00 and the HDS PRO 12 at $3,099.00, the price difference is significant. The HDS PRO 12 costs more than three times that of the Eagle Eye 9. This substantial price tag reflects the additional features and advanced technology offered in the HDS PRO 12, making it a better fit for serious anglers with a higher budget. However, for recreational users or those starting in the fishing world, the Eagle Eye 9 provides excellent value without compromising essential functionalities.
Sales Rankings
Sales rank can be an indicator of popularity and consumer preference. The Eagle Eye 9 has a sales rank of 10,007, while the HDS PRO 12 ranks at 19,756. This indicates that the Eagle Eye 9 is more popular among consumers, likely due to its lower price point and comprehensive features. If popularity and consumer trust are important factors in your decision-making, the Eagle Eye 9 stands out as the favored choice.
Which should you buy?
Choosing between the Lowrance Eagle Eye 9 and the Lowrance HDS PRO 12 ultimately depends on your specific needs and budget. If you're looking for an accessible, budget-friendly option with solid live sonar capabilities, the Eagle Eye 9 at $999.00 is an excellent choice. However, if you're a serious angler seeking advanced features, superior display quality, and intricate mapping capabilities, the HDS PRO 12, despite its higher price of $3,099.00, offers significant advantages worth the investment.
