For over ten years Armada Technologies has been developing and fielding electronic underground locators. These products have represented continuous improvement in the capability and value for users in a variety of industries. The Pro900 is the latest in that line with features that make it useful in many fields: irrigation, outdoor lighting, cable services, telephone, facility maintenance and others. The availability of two connectionless tracking modes means simpler, safer tracing of buried wires and pipes, and the use of two selectable direct tracking frequencies makes the Pro900 suitable for a wide range of wire depths and distances.
