MicroEel Analog Seismic Solid Streamer

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 flotation survives abrasive environments, proven performance in polar regions
1.1” (28mm) 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. Each hydrophone is calibrated individually, so you can prove to your client, and yourself, that there is no better way to collect data and get the job done.

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.
