Lowrance HDS-12 Gen3 comes with a 12” LCD display with an LED backlight, which means you will have no problems observing your images even in direct sunlight. The resolution of the screen is 1280 x 800 in a 16:9 ratio, making the split-screen feature much easier to use. You can operate the screen using the keypad or touchscreen functionality.
The waterproof rating in IP-X7, so the unit should have no problems handling water splashes, heavy rain, and even complete immersion in 3.3ft of water for half an hour. On the other hand, the “X” in the rating means the manufacturer has not tested it against the entry of solid objects like dust and dirt. Note that you have to keep the microSD card door closed for the waterproof rating to apply.
Sonar & Transducer
As we already mentioned in this Lowrance HDS-12 Gen3 review, the unit does not come with a transducer. The manufacturer focused its entire effort on creating the ultimate fish finder – and it is actually good that it does not come with a transducer because it would raise its already high price tag. If you already have your favorite transducer installed in your fishing vessel or are looking to buy one of the best models (we definitely recommend going for a TotalScan transducer), this unit is ideal for you.
The unit utilizes the CHIRP technology as well as StructureScan, which provides users with an optimal overview of not just fish targets but underwater structures and landmarks underneath their vessels as well. Note that you have to pair the device with a StructureScan transducer in order to use this feature. The CHIRP sonar covers 83 and 200 kHz while StructureScan operates at 455/800 kHz.
The base version of Lowrance HDS-12 Gen3 comes with Insight USA maps, which show you the most common fishing locations in the coastal areas around the US. However, the unit is compatible with the top charting options on the market, so you can upgrade it with Navionics Gold/Platinum+/NAV+, C-MAP (MAX N and MAX N+) and others.
The unit comes with a built-in 10Hz GPS/GLONASS receiver (16 channels) that allows you to pinpoint your current location, measure the overall speed of your vessel, and much more. The chartplotting function allows you to create up to 3,000 waypoints with 100 routes and 100 trails (10,000 points per trails).
You can also view the locations in 2D when necessary with an overlay provided by the StructureScan feature. The Insight Genesis app also enables you to create personal maps of your favorite fishing hotspots and locations.
When it comes to connectivity options, Lowrance HDS-12 Gen3 features Ethernet ports, Bluetooth, a microSD card reader, and the NMEA 2000 port. The internal memory of the unit is 7.8GB with up to 32GB in two microSD card slots.

It provides you with exceptional sonar capabilities, unparalleled networking options, a high-precision GPS paired with a potent chartplotter, compatibility with all the premium mapping packages, and much more. The price of the device is rather high, but you definitely get what you paid for.
