Question about my detector and headphones:confused:

[Junkfinder 2000]

I hear people talk about and even in my manual about hearing "weak" signals that I've never heard. Ive used my detector for probally over a year now and I've never heard a weak tone out of my detector with or without my headphones. My detector is a lonestar and my headphones are the cheapy bh ones. Just curious if better headphones would allow me to hear the faint tone of the deep one or is something wrong with my detector? All the tones ive got outta my detector ring out at the same volume and I do have a test garden but the deep coins in there usually dont repeat well but they dont give off any faint tones that i can tell. Thanks guys and hh!

Hi, BH detectors have an audio boost so all signals, no matter how deep, will sound the same.

I wear headphones in order to concentrate on the tones a little better and seal off outside noises and distractions.

If you hunt in DISC you are not going to hear the "weak" (faint) signals because none are produced since the detector produces a "staccato" tone instead of a rising one. But if you hunt in ALL METALS and you're wearing headphones you'll hear the "weak" (faint) signal unless you're in a noisy area which may mask the just barely audible tone. The "weakness" occurs because in ALL METALS the detector starts sounding off faintly as you approach metal. A deep target will just about trigger the detector but the tone will not increase or increase a small increment when you're over the target. If the target is shallower, as your coil approaches it you'll hear the "weak" (faint) tone increase in strength until you're over it at which time the detector's tone will be at maximum.

I didn't want to ramble but I should add the following info so that "weak" or faint signals are understood.

As it is, the tone that most detectors make in ALL METALS are on the low frequency side. There is nothing more difficult than reproducing low frequency signals at low volume. This is why most audio speakers are made large to reproduce low bass tones in the 30Hz area such as pipe organs and synthesizers create. A small box produces adequate but no real low bass tones below 40 or so Hertz.

So when you combine low signals (ALL METALS) and headphones (small speakers) you might miss a deep target especially if it's a small coin such as a (silver) dime. My old TEKNETICS MARK I LTD (and others from TEK) had a TONE knob with which you could change the frequency of the threshhold from a low grumble to a high pitch. If you were hard of hearing and couldn't hear the low tones you could advance the knob until you were satisfied.

I'm not technically-trained but I understand a little of what happens in audio. It is my opinion that detector manufacturers should consider these valuable weak or faint signals and design the audio part of the detector so that as soon as the detector detects a deep target and produces a weak or faint signal it should automatically boost the signal a few decibels so that it becomes really audible. At the same time if the target is shallow and the sound increases as the coil nears the object, the detector should attenuate the sound of the increasingly louder signal so that your ears are not blasted by the normal maximum loudness. IOW, push and pull.

Anyone technically-minded agree with this and offer a better solution?

Personally, I want the weak signals to stay weak....And the strong to stay strong.....The strong side could have a limiting circuit so your ears don't get damaged by overly loud signals, but I want those weak ones to stay just as they are...this way I know it is a tiny, or DEEP target....

The Bounty Hunter Dectectors, except for the old Red Baron and such, all have amplifiers and limiters in the audio chain...all the sounds are the same strength...Now my White's Classic II SL will give those loud signals for stuff near the surface, or large targets, and those weak or whisper signals for the small or deep stuff...On the White's if the signal is broken or long, it is usually junk, and a short clean tone is a good target (or an older pulltab or screw cap when DISC is set low), but those weak fluttery signals are often deep dimes, or small deep targets...The turtle charm I dug the other day was a weak fluttery signal right under a swing...I dug it out at about 7 inches deep...the charm is about the diameter of a dime...
