Tesoro sounds

[Lee66]

I've been using Tesoro detectors for several years and love them. But I have found it challenging to learn the tesoro language. It seemed to come pretty well with the silver uMax and compadre. Now I have a Tejon and a banditto II uMax. I'm down in my back and can't detect for a few days, wife's orders, so I've been playing with them with good and trash targets and I think it is starting to click. Just using the speaker, I can hear the harsh sound of trash targets. This is passing a good target over the coil followed immediately by a trash target. Okay here's the issue, plugged in my phones and I can't Hear the difference. I have quality jolly Rodgers phones and a cheap pair of whites. It makes no difference to my ears which pair I use. So question for the Tesoro gurus is what phones are best to hear the target nuances of the Tesoro language?

Thanks, Leeinsc

For the Tejon, I like a higher pitched tone so the iron and junk tend to crackle and the difference in tones are not noticeable.

I use Sunray Pro Golds. I have a Silver Sabre micromax. I found that with the limiter switch on it is easier to decipher good targets from bad targets. Softens the tone a little and is still loud enough to hear. If I have a coin under the coil I can tell.

Both the Sunray and the Killer B's use the same speaker, and both are super sensitive. They're made by the same guy, and either are what you want for a Tesoro.
I use the Killer B's Wasp and love 'em. ^_^

Thanks for the advice guys. Think I may have found part of the issue. The jolly ROGERS are only around 30 impedance. I've got an old set of jimmy sierras that have a short in the cord. Going to give them a try.

Any good set of metal detecting headphones, not music headphones, will enhance your detector. I use Grey Ghost originals on my Tejon. As for the Tesoro sounds, this article is a good place to start. It's made for Tesoro Tejon, but I noticed much of the sound descriptions in part 2 also work with my Tesoro Tigershark, a machine built on the Bandito platform.

Thanks. I downloaded that article when I bought my first Tesoro. Great one

and that is using what I consider to be "low end" headphones. I don't care who makes them, but almost all headphones used for detecting with a speaker impedance of 8 ohms, 16 ohms or 32 ohms [size=small](the latter of which are your Jolly Rogers which are 16 ohms nominally)[/size] to not have enough audio 'clarity' [size=small](at least for me)[/size] or sufficient distinction of what I like to her with little "on-the-edge" audio responses. They have a more 'muffled' sort of audio to them, and I have tried more headphones than most forks will ever handle.

Decades ago, after working with many different brands and models in an effort to evaluate what might be some of the better headphones for the several detectors in my personal arsenal [size=small](and that included at least three Tesoro models at the time)[/size], I found that those with a quality build design and being reasonably comfortable provided the best audio quality and clarity if they used a 100 ohm to 150 ohm speaker in each earpiece [size=small](thus 50-75 ohms nominally)[/size].

From that I settled on a few sets of headphones from Koss, to include the Optima Pro 90, if I recall the model name, that were made for the old Radio Shack, and similar headphones with a modification made for White's. These used a 100 ohm speaker and provided a little higher pitch and sharper or cleaner audio. I replace those in my carry headphones with the Killer B 'Wasp' which are basically the same style as the SunRay Pro Gold [size=small](same maker)[/size] and I usually had one or the other as a 'back-up' set of headphones.

Remember, too, that one of the problems some of us aging detector operators have is a hearing impairment, and that includes me. The USAF told me I was 'deaf' in '82 thru '87 when I applied for summer hire and took their hearing tests, and I will admit that I struggle to hear a lot of things. An on-the-job fall off a ladder injury in June of 2010 left me with a ruptured right eardrum [size=small](that used to be the better ear)[/size] and it healed with scar tissue on the ear canal and eardrum. Final treatment options were to:

1.. Cut me open, remove my eardrum and make a new eardrum and ear canal [size=small](I passed on that offer!)[/size].

2.. Fir me with a/one hearing aid because the job injury only damaged one ear [size=small](I took them up on that offer)[/size].

3.. Just get along every day without any surgery or using a hearing aid [size=small](which is what I have done, and do, the bulk of the time)[/size].

Thus, to hear detector responses better I have relied on using headphones since I started in early '65, and have been very selective and evaluated differed headphones along the way, especially since bout 1980. I have made some changes in recent years however, and still have my Killer B 'Wasp' as 'back-ups,' but have gone to more comfort. I found the 'tank-style' ear cup to have a better fit over-and-around the ears to help block out colder weather, but more importantly to block-out any ambient noise while hearing cleaner audio responses. My #1 headphones are the Killer B 'Hornet' which also use the 150 ohm speakers but fit much more comfortably.

The past several years I have also been using the White's Pro Star headphones because the also use the 'tank-style' ear cups and the audio quality works pretty well for almost every detector I use/have used them with. White's says the speakers are 50 ohm, but I haven't checked that out to know if the individual speaker is 50 ohm impedance, or if they are 100 ohm speakers, but 50 ohms nominally [size=small]( since the are used in mono and not stereo operation)[/size], but I do know they are comfortable and the audio quality is very good. I prefer the 'Hornet' as they are excellent and have the limiter option, but the Pro Star headphones are very good, work well, and I have a set I keep in use and one stored in my detector accessory bags as a back-up.

If you can get a good repair job on your Jimmy 'Sierra' headphones, I am sure they will help you hear the better audio qualities of the Tesoro 'language.'
