G-882 Marine Magnetometer | Geometrics

Features and Benefits:
Cesium Vapor High Performance: Highest detection range and high probability of detecting all sized ferrous targets.
Streamlined Design for Tow Safety: Low probability of fouling in fishing lines or rocks. Rugged fiber-wound fiberglass housing.
Sample at up to 20Hz: Unparalleled data density while also covering larger areas per day.
Sensor can be Rotated for Optimal Signal: Can be used worldwide.
Easy Portability and Handling: No winch required. Built-in easy-carry handle. Operable by a single man; only 44 lb. with 200 ft. cable.
Internal CM-221 Mini-Counter: This little counter provides multi-sensor sync and data concatenation, allowing the user to combine multiple systems for increased coverage.
Export Version Available: Use anywhere in the world without need for an export license (except embargoed countries). See specifications.

Technical Specifications:
