Recording tones on my gt

[Jiminsandiego]

So what if a person was to somehow put an audio recorder microphone inside his headphones and record the sound of a target. Then after retrieving the target, put the same headphones into the recorder and play back the tones so that he can more easily remember what that particular target sounded like. He could say out loud what the target was and in a sense make a custom "training tape". Boop Boop =nickle...Beep Beep=dime and so on. Maybe it would even be possible to wire the microphone right into the headphones. In my (limited) experience, a target (especially if deep) sounds much different at first and changes during the recovery effort. This initial "sound" or "tone" is what I would like to duplicate (and record) as closely as possible. Did that little gold ring really sound just like foil? Anyhow, I know I can't be the first one to go down this road, so is there anybody out there that can tell me how to do this?
Thanks,
Jim

After a little research I'm thinking "biaurnal" microphones ($80) plugged into an affordable portable recorder, and placed inside my ear, under the headphone's ear cups, might just work. Just gatta find a recorder that has a head phone jack and an external microphone jack. Never knew there was such a thing as biaurnal microphones. Very interesting subject (to me anyway). Any guidance is, (as always) much appreciated.
Cheers,
Jim

We would be soooo grateful for your expirement and if you would share your recordings.

That would be very useful information and
I'm sure many of us new to the Sovergn could learn
something from it.

Thanks for your effort!

You could use a splitter, 2 outputs from 1 jack, one to the headphones and one directly to the line in/mike input on the recording device, that way no ambient sound is recorded that may be picked up by a microphone, see below you may have to use a adapter to get it to fit the detector and phones unless you can find a 1/4" version

While this may sound good to us, there is a inherent problem with your project.First off all machines have there very own sound, while very very close they are all different. Then the headphones that we all chose to wear makes all the difference in the world. You can try this at home just use a different set and you'll see. Makes you wonder why the guy walking down the beach with the 1000.00 dollar detector had dollars store headphones on? There is a reason why they tell you what ohms you should use in your headphones! It would work for each person to do but to send the tones to one another would only be a close resemblance to what we each hear.

As Buried Crap NJ has stated this might work, but only for each individual person making his own recordings and using the same equipment in the field after.

You'd want to use a jack splitter because recording the audio via a mic that the headphones is putting out would distort/degrade the audio to some extent. I'm working on a project similar to this and will post some info when complete.

Thanks for all the replies! Thought for sure someone would have the "recipe". I fully understand Buried and Outlew's point that it would be a "personal thing", and that each detectorist would have to record their own tape for their specific equipment and location. However the recorder could be passed out amongst friends and club members. (To be used with their personal headphones). Also thanks Kered and Ctitterhunter for the input. The biaurnal microphone might have some advantage over other options. They are designed to accurately reproduce sound as a human being would hear it. They would "take in account" for the noise of the surf, wind, children etc.as well as the position of the headphones over the ear, perhaps giving a more accurate rendition of the recorded sound.(Also it would be easier to build and share with others). A cleaner sound might not be as accurate as a duplicate. I picture a hip mounted recorder connected to a biaurnal microphone in each ear, with my headphones over the mics and split between the detector and the recorder. I could scan the target and then listen to the recording, (before and after recovery). This would be the true test ("is it real or is it memerorex?") Then I would have a recording of sounds followed by me saying what the target actually was. ( I could then listen to it in my Lazyboy) All I need is the cheapest biaurnal microphones I can find, a splitter and....a recorder. So, hey Critterhunter got any suggestions on recorders?
Thanks again folks for the help,
Jim

Talking about individual phones, and individual hearing , my old machine would sound completely different because I have my tone turned up to be a " higher tone " machine since I went in and turned up the tone pot inside the machine ..... Jim

Maybe for a first time Sovereign user recorded tones may help.There have been Sovereign tones recorded(already been done) and posted on other sites for nickles which are usually more difficult to learn than the higher conductivity coins.Field use is the place to learn the sound of tones working with actual ground conditions.A semi experience Sovereign user who needs a recording of tones should consider another detector perhaps a National Geographic or Famous Trails Model.

The tones i have heard on the recording are not the one i hear while detecting, maybe it is the headphones or what is used for recording, but not the same.
The way to learn the tones, how fast to go or anything with the Sovereign is learned in the field on actual hunting and digging, soon you can and will see why so many of us that have stayed with the Sovereigns over the years for our serious coin detecting.
Some like to change the tones to suit their hearing, I find with my bad hearing as I am total deaf in the very high tones the way they are set up at the factory I can tell the difference real easy on my nickles versus pultabs. Also my good coins versus trash too and those close my 180 meter will tell me the difference. Tried a used Sovereign with the tones set to max that was traded in as the guy said it was hard to tell the difference in the tones and he was right as they sounded very close to one another. This is all learned from actual hunting with the Sovereign and being prepared to learn something new each time out with the Sovereign.

The way the Sovereign's tones can be adjusted to suit the individuals hearing is a GREAT feature ......As Rick says , to learn the tones is to do it the old fashioned way , you SPEND TIME IN THE FIELD ......I adjusted my Soveriegn at least 5 different ways on the " Tone " adjustment on the board ....I kept taking it appart and adjusting until I was happy with the tonal differences .....Once I was dialed into my range, it was a night and day difference ..... I could now hear the actual nuances of each target ...... Silver SCREAMED !!......Nickels, Pull Tabs, and Gold , were in a range that was still a good range for my hearing ..... Once you find YOUR range , you just know it !!.... It actually makes more of a difference than what headhones you are using .....The difference is HUGE !!.....Jim

 

[Jiminsandiego]

Wow, very interesting replies. Thanks. Just thought it might be a way to augment the learning in the field. I used to play classical guitar and could tell C from C sharp but I'll be damned if I can tell a silver dime from clad.... but I'll keep trying. ( I'll bet Segovia would use a GT)
Cheers,
Jim

One of the things is that the copper penny, clad coins or silver coins read the same numbers with the same tones. With some experience some have seen where they can tell the difference in the penny/dimes from the quarters in many cases. When i was using mine more and with the Sun Ray DTI meters I notice if you calibrated it for 179-180 on a new dime or copper penny it seem like most all the clad coins and copper would read 179-180, but as it got deeper it would bounce more in the numbers and yet you still could get the 179-180 if you didn't swing the coil too far off the actual signal. Now on the silver it seem like it would run more 180 and not see as much 179 on the meter and by going with the size of the signal could tell me it was a bigger or smaller coin.
I have been trying to tell many that you need to spend the time in actual hunting and with the Experience you will get to know which are good signals and in many time tell what it is at least 60% of the time.
The Sovereigns are a great detector right out of the box and will out perform most detectors on the market and even cost less too, but unless you get to know the Sovereign extra coils and some of the mods or amps will do you no good at all.
