Distinguishing between Lowrance HDS GEN2 and GEN3 units primarily comes down to advancements in screen technology and sonar capabilities. The GEN3 series introduced significant upgrades, including an enhanced display and integrated CHIRP sonar, making it a more powerful and user-friendly system for anglers.
Here's a breakdown of the key differences:
| Feature | Lowrance HDS GEN2 / GEN2 Touch | Lowrance HDS GEN3 |
|---|---|---|
| Screen Quality | Standard display, often described as good for its time. | Better screen with improved clarity, brightness, and viewing angles. |
| Screen Material | Plastic glued to plastic construction, which could be prone to fogging or yellowing over time. | Glass glued to plastic construction, offering enhanced durability and a premium feel. |
| Sonar Capability | Primarily features 2D-sonar with traditional broadband sounder capabilities. | Features built-in single band CHIRP sonar in addition to the 2D-sonar, providing superior target separation and clarity. |
| User Interface | Navigating with buttons and touch (on Touch models). | Often includes a more intuitive, modern user interface, supporting multi-touch gestures. |
| Networking | Standard networking options (Ethernet, NMEA 2000). | Enhanced networking capabilities, often with integrated wireless connectivity (Wi-Fi, Bluetooth). |
Detailed Differences Explained
Screen Technology and Construction
One of the most noticeable upgrades in the GEN3 HDS units is the display. The GEN3 boasts a better screen compared to its GEN2 predecessors. This typically translates to higher resolution, brighter images, and better visibility in various light conditions, including direct sunlight.
Beyond the visual quality, the physical construction of the screen also differs significantly. GEN2 and GEN2 Touch models utilized a plastic glued to plastic method for their display assembly. In contrast, the GEN3 models feature a more robust glass glued to plastic construction. This change not only contributes to the improved clarity and touch responsiveness but also enhances the unit's durability, making it less susceptible to scratching and environmental wear over time.
Advanced Sonar Capabilities
A major leap in fishfinding technology is evident in the GEN3 series. While GEN2 models were equipped with capable 2D-sonar, the HDS GEN3 units elevate the game with built-in single band CHIRP sonar.
- CHIRP Sonar: This technology transmits a continuous sweep of frequencies (chirps) instead of a single frequency burst. The result is superior target separation, clearer returns of baitfish and game fish, and better depth penetration. This integration means you get a more detailed and accurate view of the underwater world directly from your unit, enhancing your ability to locate fish and structure.
User Experience and Connectivity
While not explicitly detailed in the reference, the generational shift often includes improvements in the overall user interface and connectivity. GEN3 units typically offer a more streamlined, modern interface with multi-touch gestures (on touch models), making navigation more intuitive. Furthermore, GEN3 systems often come with integrated wireless connectivity (like Wi-Fi and Bluetooth), allowing for easier software updates, GoFree cloud access, and integration with other marine electronics and mobile devices.
Understanding these key distinctions will help you identify and appreciate the advancements brought by the HDS GEN3 series over its GEN2 counterparts.
