Using The Detector; Searchcoil - Fisher F44 Owner's Manual

THE BASICS OF METAL DETECTING
The searchcoil produces a magnetic field and then detects changes in that
5. EMI (Electromagnetic Interference)
magnetic field caused by the presence of metal objects. This magnetic field
the detector creates is also susceptible to the electromagnetic energy
produced by other electronic devices. Electric fences, cell phones, cell phone
towers, power lines, microwave ovens, lighting fixtures, TVs, computers,
motors, etc., all produce EMI which can interfere with the detector and cause
it to beep erratically.
The SENSITIVITY control lets you reduce the strength of this magnetic field
and therefore lessen its susceptibility to EMI. You may want to operate at
maximum strength, but the presence of EMI may make this impossible. If you
experience erratic behavior or "false" signals, reduce the sensitivity.

USING THE DETECTOR

Sweep the detector side-to-side over
Sweep Method
the ground.
Keep the searchcoil parallel to the
ground as you sweep; do not lift the
searchcoil at the ends of your sweeps.
Searchcoil motion is required for target
detection.
11" WATERPROOF SEARCHCOIL
This detector is equipped with an 11" triangulated elliptical concentric
waterproof searchcoil. This lightweight, ruggedly constructed searchcoil
can be fully submerged into water. The bottom portion of the pole assembly
can also be submerged, but the control housing and the searchcoil cable
plug connection into the housing must not be submerged.
weatherproofing on the F44 was designed to allow hunting in inclement
weather but it was not designed to withstand submersion in water.
Accessory searchcoils are also available for purchase; see back cover or
visit www.fisherlab.com. A smaller searchcoil offers more precision and fits
into tight spaces. Larger searchcoils provide for more ground coverage on
each sweep and penetrate deeper into the ground. Biaxial searchcoils
provide better penetration in mineralized soils.
