Use with headphones
The TX-850 is equipped with ¼” headphone jack. Any headphones with a stereo plug will
work. Headphones with a mono plug will not work. Using headphones extends battery
life, also prevents the sound from bothering bystanders. In also allows you to hear
subtle changes in the sound more clearly, particularly if searching in a noisy location.
Gold nuggets are often very small; se closely monitoring changes in sound using
headphones will improve your gold prospecting results. For safety reasons, do not use
headphones near traffic or where other dangers, like rattlesnakes, are present. This
device is to be used with interconnecting cables/headphone cables shorter than three
meters.
The basic of metal detecting
A hobby metal detector is intended for locating buried metal objects. When searching
for metals, underground or on the surface, you have the following challenges and
objectives:
•
Ignoring signals caused ground minerals.
•
Ignoring signals caused by metal objects that you do not want to find, like pull-
tabs.
•
Identifying a buried metal object before you dig it up.
•
Estimating the size and depth of objects to facilitate digging them up.
•
Eliminating the effects of electromagnetic interference from other electronic
devices.
Your TX-850 metal detector is designed with these things in mind.
1) Ground Minerals
All soil contain minerals. Signals form ground mineral can interfere with the signals from
metal objects you want to find. All soils differ, and can differ greatly, in the type and
amount of ground minerals present. You therefore want to calibrate the detector to the
specific ground conditions where you are hunting. The detector incorporates both
automated and manual ground balancing features which will eliminate false signals
from most types of soil. To maximize the detector’s target identification accuracy and
depth of detection, use the GROUD GRAB ® (GG) function to calibrate the detector to
the ground where you are searching. See the section on GROUND BALANCING for
details.
