Introduction

The state-of-the-art DML2000-XR Magnetic Locator packs all of its sophisticated electronics

into a nicely balanced, water resistant package weighing less than 2 pounds. O-rings are used

to shock mount the sensors and thus ensure proper instrument operation. The electronics'

housing is water resistant and unaffected by rain and snow; the sensor tube is waterproof and

can be submerged in shallow water up to 3 feet.

The unit has six sensitivity settings for better control. Normal locates are performed on setting

two or three. Lower settings may be used for large, relatively shallow targets; higher settings

work best for weak or deep targets. The instrument audio output idles at a nominal 20 Hz when

no magnetic objects are present and increases whenever the DML2000-XR approaches a

magnetized object.*

The DML2000-XR Magnetic Locator is the ideal instrument for locating survey markers, septic

tanks, buried iron or steel pipes, water valves, water meters and any other ferrous objects

covered by dirt, pavement, water, snow or ice. The capabilities of this instrument are unlimited,

and an experienced operator will find many uses for the DML2000.

The separate Power/Volume and Sensitivity controls allow the operator to leave the Sensitivity

control in a favorite or preset position, deactivate the instrument and later resume operation

with this setting unchanged.

There is no need to worry about the instrument battery level. A built-in Low Battery indicator

begins flashing whenever the operator has 2 to 3 hours of normal operation remaining.

Typically the DML2000-XR will provide over 60 hours of operation from a set of 4-AA, alkaline

batteries. Using lithium batteries can increase this to over 100 hours of operation.

*BEWARE! A strong warble output from the instrument means you are probably over an

energized power line; a weak warble output often indicates the presence of a telephone or

communications cable.
