MicroEel Analog Seismic Solid Streamer

MicroEel
  • Available in 1 to 24 channel configurations
  • State-of-the-art, low noise, high sensitivity polymer hydrophones provide stable, accurate response
  • 12 inch (31cm) bend radius winds easily on small winches
  • Extremely lightweight, deploys easily by hand
  • Proprietary floatation survives abrasive environments, proven performance in polar regions
  • 1.25” (31 mm) diameter design makes for easy shipping, deployment and retrieval
  • Unique design isolates vibration and suppresses ship and towing related noise

Stable response under wide temperature and pressure environments. Easy balancing in a wide range of salinities. No hazardous and costly liquid floatation. Easy transport on commercial airlines without hazardous goods hassles. Geometrics solid streamers have the performance and reliability that allow you to stay out longer, have less down time and collect data where other streamers cannot go.

Geometrics solid streamers are backed by an unprecedented warranty and support from our world-wide repair network. Call us today to try one out on your next cruise.
