User Experience 

Performance 

The CHIRP sonar on HDS-7 uses dual-beam frequency to give you a clear view of what’s under your fishing boat. With its 83 kHz frequency, you get a 60-degree conical coverage, covering a huge area in one sweep but with reduced accuracy. With the 200 kHz beam, you increase the fish finder’s accuracy while enjoying a 20-degree conical coverage. Going down to a depth of 750 feet, HDS-7 ensures that you do not miss any target with the CHIRP sonar. 

The StructureScan HD utilizes 455/800 kHz to offer picture-perfect clarity with its DownScan and Sidescan imaging. The 455 kHz works well for all available depths. However, if you are fishing in shallow waters, the 800 kHz frequency will be more ideal for you. 

Both the StructureScan HD and CHIRP transducers come with temperature probes. They constantly feed your main unit with data, allowing it to show variations on the implemented temperature graph. 

HDS-7 also offers flasher sonar, Bottom Lock, Split Zoom, and Fish ID. The flasher function is perfect for people who enjoy ice fishing, thanks to its circular layout. Fish ID utilizes suggestive icons to mark the results generated by the sonar. The Bottom Lock feature shows you a flattened bottom, providing an ideal view of fish targets while the Split Zoom allows a closer look at specific portions of your sonar view. 

Display and Resolution 

Lowrance HDS 7 fishfinder comes with a 7-inch display. With its TFT LCD screen, you get to enjoy a 16:9 aspect ratio and a resolution of 800 x 480. The display guarantees maximum clarity, helping you avoid confusing your targets with other underwater structures. 

The display on Lowrance HDS-7 Gen-3 has a LED backlight. This enables anglers to observe the imaging generated by the sonar without experiencing difficulties when exposed to direct sunlight. 

Navigation and Progress Tracking 

HDS 7 comes with a built-in GPS with a 10 Hz position update rate and WAAS/EGNOS correction. You can store 3,000 waypoints on the fish-finder, 100 trails with 10,000 points for each trail, and up to 100 routes. The device supports Broadband Radar, Class B AIS, SiriusXM, and autopilot systems such as SmartSteer, MotorGuide, PinpointGPS, and Lowrance Outboard Pilot.

HDS-7 Gen-3 comes pre-loaded with Insight USA charts for both inland and coastal waters. Its StructureMap feature works together with sonar to customize your maps instantly, increasing situational awareness. 

With its Trackback function, you can scroll through the sonar log and review various locations. All this shows that the fish finder is extremely versatile when it comes to both navigation and tracking the fishing progress. 

Durability 

Coming with a rugged build, Lowrance HDS-7 Gen-3 can handle the conditions in which it is used. With an IP-X7 waterproof rating, the fishing aid can’t handle rain and accidental water splashes. 

With its card door closed, the fish finder can handle submersion in waters of up to 3.3 feet for 30 minutes. This tells you that you won’t have to worry about water damage when you are out on your favorite fishing spot with HDS-7 Gen-3.
