COMPACT, STREAMLINED 4-KW DOME RADAR

Features may include:
  • If your boat has limited space for radar placement, this compact dome is for you.
  • It packs the power and echo definition you need, at all ranges.
  • When weather and sea conditions shift, the gain and sea filter do too — automatically.
