When you need world-class performance, you want the world’s best gear. The new Lowrance HDS-7 Generation 2 multifunction displays are a cutting-edge fishfinding and navigation innovation. The HDS family was created for power users who want state-of-the-art technology in a simple to install, use, and get the results they desire.

The newly implemented operating system has simplified the user interface, allowing you to access your preferred features with a single touch of a button. A boat with an HDS unit as its centerpiece is truly “modern” and “fully equipped.”

See sonar data like never before on the crystal clear LCD screen with a 6.2-inch display that supports split-screen views. With 250 Watts of power and a twin frequencies of 83kHz and 200kHz or 50 kHz and 200 kHz, this equipment can see as far as 600 feet at 83 kHz, and 250 feet at 200kHz, revealing structure, temperature changes, baitfish, and predator fish in great detail.

You may even integrate several units together to share data from just one receiver (whether it’s a transducer, radar, or weather).

  • 83/200/455/800 kHz Transducer
  • 50/200/455/800 kHz Transducer, US/Canada Coastal, Great Lakes, Major Canadian Lakes Charts
  •  83/200/455/800 kHz Transducer, US/Canada Coastal, Great Lakes, Major Canadian Lakes Charts


StructureScan is a powerful tool to examine the underwater environment. StructureScan(also known as LSS-2) fires three sonar beams – yes, three – one high-power (455 kHz or 800 kHz) DownScan imaging, and two SideScan beams to give you both images at once! With the enormous screen sizes, split screen may be used to view data from all SONAR beams at once!

Because you can pick and choose what frequency range to view, it’s possible to have one area that displays 83 kHz, another that displays 200 kHz, a third that shows DownScan, and yet another one that shows SideScan at the same time. There’s nothing better than this in terms of fishing!


All Lowery-series HDS-7 units are fully compatible with all Navionics chart cards, Platinum+, Platinum, Platinum HotMaps with satellite imagery, aerial photographs, and 3D views.


Through an affordable and integrated smart antenna/module bundle, the Lowrance HDS-7 unit will link with SIRIUS satellite high-res NOWRad weather radar and radio services. In addition to Coastal coverage (subscription required), the first SIRIUS Inland weather service will be available.


Combine data from the chart with underwater structure data (requires an additional StructureScan Module) for a more lifelike experience on your display.

When linked to your display, the external radar dome may be used for sensors and can also be networked, allowing you to add radar functionality to it, making it a vital safety tool in poor weather and limited light.

My name is Shane Baker and when I am not with my family or working here I am out fishing! I caught my first fish when I was 6 – it was a trout at a stocked pond here in TX. Ever since fishing has been a passion of mine!
