Light Weight Telex Earphones
Order Number 1417 - Telex Earphones with Diode Suppression
Order Number 3377 - Standard Telex Earphones without Diode Suppression
We have been selling these earphones for the past 17 years or more and they have become a must have for the vast majority of professional prospectors on the Victorian goldfields.
Fitted with "diode suppression" (a term coined by Finders to identify our modification) they are unsurpassed for prospecting in areas where outside background noise is not a problem such as the remote bush regions found on the Australian goldfields.
Finders was the pioneer of using "diode suppressed" headphones for detecting and even today many are not aware of the benefits to be had from this method of signal limiting.
One of the important features of these earphones is that they are worn under the chin stethoscope style which allows a wide brimmed hat to worn in the hot weather.
Another feature is the efficiency of the transducer which has the ability to lift the weaker target signals out of the background noises.
The most important feature of all is the high impedance of 500 ohms which allows them to be effectively fitted with clipping diodes ("diode suppressed") (clipping diodes are not effective on low impedance headphones). Unlike a volume control which attenuates weak signals into the background and thus negates any benefits of using headphones "diode suppression" has no loss effect on weak or soft signals but limits the volume to a comfortable level on large and loud targets.
