Picture-Perfect Fishfinding

  • Thermoclines Exposed – clearly see the boundary layer between the lower cooler water and, upper warmer, oxygen-rich zone where fish hang
  • Fish Truly Revealed – Mark-5x DSI imaging leaves nothing to the imagination, clearly showing predator fish and baitfish schools
  • Bottoms Uncovered – you easily distinguish between hard and soft bottoms, as well as fish and structure on/near the bottom
  • Structure Disclosed – with photo-like views you can recognize all manner of structure at a glance, like bridge pilings, laydowns, ledges, drop-offs, vegetation, wrecks; no interpretation needed
