Lowrance StructureScan 3D allows anglers to see fish, structure and bottom contour in a stunning three-dimensional view. StructureScan 3D imaging scans underwater terrain and fish-holding structure to create a high-resolution, 180-degree, three-dimensional view beneath your boat. With this unique imaging view, anglers gain a better understanding of where fish and structure are located in relation to their boat.

StructureScan 3D

StructureScan 3D is powered by a multi-beam sonar technology that produces revealing images with stunning detail by converting scans of underwater terrain and fish-holding structure into high-resolution, 180-degree, three-dimensional views.

Easy-to-Understand Sonar Images

View 3D images from any angle with ScanTrack pan-tilt-rotate control using on-screen touch commands and easy-to-use, preset viewing positions.

Find Key Fishing Areas Faster

StructureScan 3D allows anglers to more easily understand where fish and fish-holding structure are located in relation to their boat. By slowly idling over a potential fishing area with the wide, 180-degree scanning range, anglers can quickly search for key areas and cover – such as abrupt depth changes, points, ditches, rockpiles, brushpiles, weedbeds standing timber, wrecks and more.

Unrivaled SideScan Image Clarity

To ensure the clearest possible SideScan views, the StructureScan 3D transducer design has been enhanced with an increased number of sensors for greater imaging performance.

High Definition (HD) and Super-Wide 3D Scanning

The contours below the water’s surface can be shown to the sides of the boat – up to 600 feet port and starboard – with incredibly detailed, high-definition views. StructureScan 3D provides multiple views, including two-dimensional DownScan Imaging and StructureScan HD, and the new, realistic three-dimensional views. Using preset virtual point-of-view angles or ScanTrack pan-tilt-rotate control mode, you can adjust the view and perspective beneath your boat. Combine custom HD and 3D views to increase your understanding of how fish relate to cover and to search fishing areas more effectively.

Leading Edge Scanning Reference

The Leading Edge scanning reference provides a clear graphical illustration of sonar beams as they intersect with bottom contours. The depth and range of the most recently scanned area are shown as red fan-shaped markers directly under the boat. Leading Edge also includes a depth scale that shows greater depth detail as you zoom in, giving you a better sense of target depth.

Waypoint Overlay

Revisiting fishing areas, structure and other underwater features is easy with the Waypoint Overlay feature. Use the waypoint keypad to save a waypoint at the boat location, or switch to cursor mode, and save a waypoint over specific targets, baitfish or cover.

Automatic 3D Image Settings

Fine-tuned 3D image settings are set by your HDS Gen 3 default configuration and StructureScan 3D Module. Adjustments can be made to Surface Clarity and Contrast settings using the on-screen slider-bar. Surface Clarity reduces on-screen surface clutter, by decreasing the sensitivity of the receiver near the surface. Contrast lightens/darkens the color palette to make fish and structure easier to see.

Ethernet Connectivity

Ethernet ports allow connectivity for up to three networked devices.
