Musical Tuner

I have have read a article about a person who like myself cant distinquish the different tones
that my explorer makes when detecting.
In this atricle the guy SAYS he hooked up a Guitar tuner where the headphone jack is, then ran that into the tuner, then on the out jack on the tuner pluged his head phones in there
The the writer in this article says that the tuner then gives out a musical note instead if the regular Explorer tones which were much more easy to distinquise If anyone has done this I would greatly apreceate information on which tuner you use Thanks Dave
 
Hi Dave. I tryed it found out the meter reads voltage from coil & The volage must be going threw A osilator to make the higher pitch & tone.The higher the return voltage the higher the squeal.So a meater on volage is better than A tuner for pitch.
The y jack is A handy thing to have iff hunting with someone with exp. who knows what to listen to. Just plug your haedphones in & listen to what they hear.I can find nickels now it's A lower pitch. So iff ya can't hear it get A better set of headphones.
Right now i'm cramming a set of cd player power speakers @ $5 into a old pair of headphone hearing protectors( witch I should of been using last 20 years at work) & can hear real good at volume of 2.HH J

Russ,
You realy feel these are louder than the Timberwolfs?? Have you tried the Timberwolfs yet with the limiter turned off?? The Timberwolfs have a higher Impedence also.
I had a guy that had a set of the Sennheiser I beleive or something like that for a name as he said they were very loud, but when I tried them the Timberwolfs were louder for me.

Hi Dave .. i made a post about the same thing over a month ago and didnt have much luck. we probably read the same thing. i wrote the guy (several times) that originally wrote about it and never heard back from him. its my understanding that a regular guitar tuner wont work. it needs to be a differant kind. i havnt had the time to check into it yet, been to busy digging up coins ..lol .. but if i do find one i will let you know. once i got a good pair of headphones i didnt have that hard of a time telling the differance. good luck and HH ...
 
The HD 25 by Sennheiser are able to be very painfull if played too loudly.With 1 milliwatt they will be 120 dbl.Most headphones would be between 100 and 108********(compare to Table B.1: Ballpark figures for the dB-SPL level of common sounds.

Warshofsky, and the Editors of Time-Life Books, Sound and Hearing <http://www-ccrma.stanford.edu/CCRMA/Courses/152/hearing.html>, Life Science Library, Time-Life Books, Alexandria, VA, 1965, p. 173.

Human breathing (at 3m) 10

Sensitivity (loudness): A measure of headphone efficiency in dBs SPL per milliwatt of input. A low number means that the headphones need more power to sound as loud as those which have a higher sensitivity. Headphones for portables need to be fairly sensitive because of the lower power output of portable stereos. Modern dynamic headphones have sensitivity ratings of 90 dB or more. When shopping for portable headphones, look for a sensitivity rating of 100 dB or greater.
Impedance: A measure of headphone load on an amplifier and stated in ohms. This factor is less important with solid state amplifiers, which can drive most headphone impedances, but can be significant with tube amplifiers, which are more sensitive to load impedances. Both consumer and professional headphones generally have impedances of less than 100 ohms. There are professional models rated at 200 ohms or more to minimize loading effects on distribution amplifiers which are often drive a whole bank of headphones at one time. Be aware that very high impedance phones may require more power - on the order of Watts instead of milliWatts.
 
I see several sets on E Bay and will have to try a set and see how loud they are and let you know if they are louder than Timberwolfs.
