DO
I REALLY HEADPHONES?
It is a fact that all land based metal detectors produce an audio
signal when they pass over metal targets. It is also true that when
you first hear these signals, they seem to be shockingly loud. So,
it would naturally seem to follow that a metal detector's external
speaker should be totally sufficient. Why then do experienced detectorists
always use a set of very good headphones? Furthermore, what makes
a headphone "very good" in combination with a metal detector?
Let's explore some of the reasoning involved in headphone usage.
Imagine yourself lying back on a lounge, soaking up the sun in
a local park, or at the water's edge. Some one comes along, plunks
themselves down five feet away, and blasts a boom box at you during
the time that you had set aside to unwind. That would be downright
rude. All sports and hobbies have an etiquette as well as a code
of ethics and sense of fair play. Metal detecting is no different,
and it is highly discourteous and quite offensive to hover around
some one while your detector beeps away. Do this long enough and
you could provoke someone into summoning a person with the authority
to exclude you, your detector and other detectorists from the area.
On the other hand, let's assume that you are not an especially
socially conscientious person. Well, okay... what you really care
about is finding a lot of STUFF! So, now we come to one of the greatest
reasons to use a headphone. You will be able to better hear those
faint, deep signals, and more easily discern smaller items which
might be lying on edge. This will allow you to find more items.
Additionally, many distracting exterior sounds such as wind, waves
and wolves will be muted. Okay, If you insist upon hearing the wolves,
leave one earcup askew!
If you are fiscally oriented in the same direction as many detectorists,
then you have an economical streak in you and undoubtedly enjoy
getting something for nothing. Well, the use of a headphone will
save you money by allowing the batteries in your detector to last
longer. This is because the speaker in the detector is turned off
when the headphone is plugged in to it and so, no energy is required
to drive the detector's external speaker.
"But," you say "I already have a great set of headphones
for my stereo or multi-media system. Can I use them?" The answer
is "Maybe." If you can answer all of the following questions
with a yes, then you probably can.
Does your headphone have a volume control on each ear?
(Most detectors don’t have a volume control, and you don't want
your ears blasted.)
Does your headphone have moisture resistant mylar speakers?
(Paper cone speakers deteriorate from moisture and eventually mute
soft signals.)
Do you know if your detector has a stereo jack?
(If stereo headphones are used with a detector that has a mono jack
you will get sound in only one ear.) (Of course, you might want
to listen for wolves with the silent ear.)
The components, frequencies, and Ohms in metal detecting headphones
are specially selected to allow you to hear the best with most metal
detectors. Most headphones have a selector switch or adapter so
that you can use them with all of the detectors that you own. Some
specialty headphones can process the audio of metal detectors for
maximum depth as well as safeguard your hearing against overly loud
signals. These will automatically match your detector's preferential
Ohms.
