The Geospace Navigator bird is a streamer depth control device, used with a high-resolution seismic system to regulate and record the depth of the streamer.
The Geospace Navigator bird is a streamer depth control device that can be used to regulate and record the depth of the streamer. They have a depth accuracy of +/- 0.15 m and are used with a bird float.
Specifications
