SeaSPY

Workhorse System

A reliable high sensitivity magnetometer with unmatched absolute accuracy. It’s also the only longitudinal gradiometer on the market. Side Scan integration is also available, as are horizontal transverse gradiometers.

Applications:

Ideal for cable and pipeline survey

Deployments:

Boat TowSide Scan

Gradiometry Systematized

Rigid frame gradiometers are best suited for short-baseline applications where relative positional accuracy is key.

Eliminate geological and diurnal interference to detect small ferrous targets in real time.

Track cables or pipelines from relatively high towing altitudes.

Start recovery efforts while the survey’s still in progress.

Build Quality

Specialization matters

Time Synced Precision

Short Baseline Eliminate geological and diurnal interference, and emphasize near-surface objects in real-time so that recovery efforts can be started while the survey is in progress.

Fold and Go

Anodized composite frame Reduces drag by a factor of 10. It’s lighter to carry on land but actually stronger. New!

Maintain Control

Sleek stable Design Resists snags and minimizes impacts. The polyurethane coated tail with molded fins acts as a bumper, while creating a stable towing platform.

Integrated Tracking

Unmatched Absolute Accuracy 0.01 nT accuracy and unmatched repeatability between sensors ensures best possible data.

Build Quality 5

Quick Glance Diagnostics Automatic power supply cutoff, and leak detection give you plenty of time to pull the mag before damage.

Build Quality 6

Works Instantly on Power-up Data collected at –40°C will be identical to data collected at +60°C even without warmup.

Make SeaSPY2 H-Grad a perfect fit for your application.
