This is a 9-pin HDI Skimmer transducer from Lowrance that combines traditional 2D sonar with down-scanning imaging in a single unit.

• Hybrid Dual Imaging design pairs broadband 2D sonar with DownScan Imaging to show both fish targets and detailed structure
• Operates across 83, 200, 455, and 800 kHz frequencies for a mix of wider coverage and fine detail
• Down-scanning view renders structure and cover beneath the boat with picture-like clarity
• 9-pin connector and black housing

Available from Mirage Fish Finder, this HDI Skimmer brings 2D and down-scan sonar together for a fuller view below the hull.
