Lowrance Elite-4 HDI and Mark-4 HDI Fishfinders, Plotters and Combos
Lowrance’s Elite-4 HDI and Mark-4 HDI series bring compact, high-definition sonar and chartplotting technology to anglers and boaters who need reliable performance in a small package. Both models feature a 4.3-inch high-resolution display available in grayscale and color, offering approximately 36% more usable screen area compared with previous-generation units. The increased screen area improves readability and makes it easier to view sonar returns, maps, and navigation data at a glance.

The HDI line is designed around several key technologies and conveniences. A built-in GPS antenna gives instant position fixes for marking waypoints and navigating back to productive fishing spots. High-definition mapping options are supported, enabling more detailed chart and coastal information when paired with compatible maps. Hybrid Dual Imaging technology is a standout feature: it merges a broadband CHIRP-style sounder with down-scan imaging so users get both clear, traditional sonar arches and crisp photographic-like bottom and structure detail from beneath the boat.
Hybrid Dual Imaging effectively combines the strengths of two sonar approaches. The broadband sounder provides sensitive fish detection and improved target separation, while the down-scan imaging delivers a detailed view of structure, cover and bottom composition. Together this helps anglers more accurately identify fish holding areas, submerged timber, rock edges and other features that influence fishing success. On a 4.3-inch screen, the layout is optimized to present both sonar and map data clearly without overwhelming the display.
Installation and everyday use aim to be straightforward. The built-in GPS antenna reduces the need for external accessories, and the units are available in fishfinder, chartplotter and combo configurations to suit different preferences. Whether you choose a standalone sonar model or a combo with mapping capability, the HDI series is intended to offer a balance of feature set and affordability.
Pricing for the Elite-4 HDI and Mark-4 HDI models is positioned to be accessible, with a range from approximately $149 to $469 depending on configuration and included features. This makes the HDI series an attractive option for anglers who want advanced imaging technologies and charting support without moving up to larger, more expensive displays.
Lowrance has long been recognized for developing tools that help anglers find and catch fish more efficiently, and the Elite-4 HDI and Mark-4 HDI continue that tradition by packing hybrid sonar, GPS and mapping compatibility into compact units. The 4.3-inch high-resolution displays, enhanced usable screen area, and Hybrid Dual Imaging make these models a good fit for small to mid-sized boats where space is limited but performance is still a priority.
