Navigator Bird

 

PRODUCT DETAILS

The Navigator streamer bird depth-control system provides new standards of efficiency for offshore marine streamer acquisition. The Navigator features very high lift force at low towing speeds, extremely low power consumption, and robust, modular mechanics for superior system reliability.

Features

  • By utilizing hydrostatic water pressure, trim is continuous and instantaneous
  • Battery is not regularly consumed for trimming
  • Minimum 10 months of battery life
  • 75 pounds of lift at 5 knots
  • Measures Earth’s magnetic field in addition to magnetic heading
  • Detection, reporting, and recording of magnetic anomalies possible
