The document describes the DELPH Mag Locator tool, which allows for real-time magnetic anomaly mapping during marine magnetic surveys. It reduces infrastructure needs by using a single magnetometer and DELPH Mag Locator. The tool includes components for real-time and post-processing magnetic anomaly mapping. It performs automated filtering, georeferencing of magnetic data, and builds 3D maps in real-time. These maps can be overlaid with other sensor data and measured. The tool integrates with DELPH Sonar and RoadMap for multi-sensor correlation and export of maps and data.

Introduction
DELPH Mag Locator is a tool designed to boost your productivity while
completing your survey
It dramatically reduces the infrastructure required by a magnetic survey:
1 Magis + 1 Mag Locator = Real-Time Magnetic Anomaly Mapping
This unique See And Act concept offers the capability to interpret
information during survey and save ship time
