The latest generation of sonar imaging modules provides best-in-class range and resolution so you can see in picture-perfect detail what's beneath your boat for the ultimate fishfinding/navigational experience.

  • Highly detailed structure and fishfinding clarity
  • Vastly improved range and resolution compared with the original StructureScan®
  • Panoramic underwater imaging with SideScan and exclusive DownScan
  • Picture-perfect detail
  • Left, right and straight down coverage


The Simrad StructureScan® HD unit is a black box sonar imaging module designed to connect direct to Simrad NSS, NSE or NSO chartplotters / multifunction displays.

Following the success of the original StructureScan®, the latest HD generation delivers greater resolution and wider range for enhanced underwater images.

A crisp, clear view to the left, right and directly beneath the boat provides anglers with a superior fish-finding experience by offering a highly detailed view of ledges, channels, drop-offs and wrecks where fish conceal themselves.

It's not just a tool for fishing though… The picture-perfect images allow divers to seek out the best spots before they enter the water and also allow general boaters to explore what's beneath their boat and the perfect spot to drop anchor.
