Lowrance HDS-7 Review

The Lowrance HDS-7 multi-function display we tested was equipped with an internal broadband sounder and internal GPS sensor. The package shipped with an 83/200 kHz transom-mount transducer.

It also came preloaded with Lowrance Nautic Insight U.S. Coastal cartography. Other gear included is mounting bracket, operations manual, installation manual, quick start guide, and a combination NMEA0183 data/power cable.

The HDS-7 can be purchased as a standalone chartplotter or standalone fishfinder. The HDS-7 display unit measures 6.4-inches high by 8.8-inches wide and with a depth of 3.5-inches. A removable front bezel allows for flush panel mounting without any additional hardware needed, other than mounting screws.

Connectivity

When connected to the appropriate sensors the HDS-7 can also display radar data, Sirius weather and radio, and even engine gauges. It also works with the new Lowrance StructureScan system.

Lowrance HDS-7

A single cable that fastens to the case back with a twist lock connector supplies power and NMEA0183 data through individual branches.

Even though the MFD itself has a GPS sensor, the unit can still use an optional external GPS antenna if needed or desired. We used the internal antenna for this review.

NMEA0183 supports the high-speed data transfer rates of up to 38,400 baud that are needed to interface with most modern AIS units. This MFD can also interface with a NMEA2000 or Navico Ethernet network, each has its own connector on the unit back.

The Lowrance HDS-7 has a single chart card slot and can use a Navionics Platinum or Platinum+ chart card if desired.

Screen Size and Viewability

The HDS-7 displays data using a 5.1-inch wide by 3.8-inch high display screen. The screen measures 6.4-inches on the diagonal and carries 640 by 480 pixels of resolution.

The Lowrance HDS-7 is display screen is bright, sharp, and easy to read. When viewed straight-on the display screen maintains its brightness whether or not the user is wearing polarized sunglasses.

Even at steep side angles I noted no darkening or reduction in readability. No screen fogging was apparent in the display at anytime during my testing. I rated the Lowrance HDS-7 excellent for daylight viewability.

The HDS-7 has two color palettes, day and night. Night palette darkens onscreen numbers and letters for easier night viewing. When viewing the sounder page with night palette you’ll find colors invert.

Screen brightness levels can be set to one
