Lowrance HDS-10 Review

Updated August 2026: The HDS-10 reviewed here is an older Lowrance generation. If you’re shopping for a similar current 10-inch system, see our Lowrance HDS PRO 10 review. We’ve kept the original review below for owners, comparisons, and used-market research.

The Lowrance HDS-10 tested here is a big screen multi-function marine GPS chartplotter and Broadband Sounder ™ combo. It was loaded with Lowrance Nautic Insight ™ U.S. Coastal cartography.

The HDS-10 package ships with the display unit, mounting bracket, dual-frequency transom-mount transducer, operations manual, installation manual, quick start guide, and a combination NMEA0183 data/power cable.

The HDS-10 display can also be purchased as a standalone chartplotter or standalone fishfinder. The display unit measures 8.9-inches high by 12.3-inches wide and 3.6-inches deep.

We used the accompanying gimbal bracket to mount the Lowrance HDS-10 to our test rig. A removable front bezel allows for panel mounting without any additional hardware other than mounting screws.

The Lowrance HDS-10 has a two chart card slots and can use Navionics Platinum and Platinum+ charts as well as any Navionics inland lakes cards.

Lowrance HDS-10

Connectivity

When connected to the appropriate optional sensors the Lowrance HDS-10 can also display radar data, Sirius marine weather and radio, broadband side scanning sonar, or engine gauges. A single cable with a twist lock connector attaches to the case back and supplies power and NMEA 0183 data through individual legs.

The display contains an internal 16-channel GPS sensor, alternatively the unit can use an optional external GPS sensor if needed or desired. I used the internal antenna for this review. supports data transfer rates of up to 38,400 baud. This unit can also interface with NMEA 0183 devices, a NMEA 2000 or Navico Ethernet network.

Screen Size and Viewability

The Lowrance HDS-10 is equipped with an 8.5-inch wide by 6.4-inch high display screen. The high contrast screen measures 10.4-inches on the diagonal and sports a very respectable 800 by 600 pixels of resolution.

I found the Lowrance HDS-10 display screen to be clear, bright and easy to read. Only the smallest detail requires a close examination of the screen, but this is expected today with the enormous amount of fine detail shown for most areas.

When viewed from straight out front the HDS-10 display maintains excellent screen brightness even when wearing polarized sunglasses. At steep side angles I noted a small amount of screen darkening but little reduction in readability.

I rated this Lowrance chartplotter sounder excellent for daylight viewability. No screen fogging was apparent in the display at anytime.

The Lowrance HDS-10 has both a day and night color palette. The night palette changes numbers and letters onscreen to a darker color for easier night viewing. Other than that it has little to no effect on the radar or chart pages while o
