Headphones-
The headphone jack on the MXT Pro is located on the
control box above the battery compartment. There is a dust
cover on the headphone jack that needs to be removed
before the stereo plug from the headphone is inserted. Re-
place this cover when headphones are not being used. Most
users prefer high quality stereo headphones so White’s has
chosen to wire the headphone jack for stereo. If you have a
mono headphone, you can purchase an adapter that will al-
low sound in both ear pieces. Some headphones come with
a switch for stereo or mono jacks.
In choosing headphones, make sure they have a VOLUME
CONTROL, as there is no target volume control on the MXT
Pro. This is an important comfort issue. Remember that you
want the faintest THRESHOLD “hum” possible but a strong
comfortable target signal. With headphones you will be able
to work with a lower THRESHOLD “hum”, hear fainter target
signals, avoid bothering others with a “beeping” box, and
save on battery life. Many high quality headphones from
full ear enclosure to lightweight summer models that offer a
bit more safety in snake and bear country are available on
the market. Higher impedance headphones (60 Ohms or
greater) give the most sensitivity and are better for hearing
the tiny targets most likely to be heard while prospecting.
Properly balanced impedance is important as well as low
distortion.
