Follow-up Headphone Question

[Joe Pack]

I posted a question on the general forum re: the necessity of a sound limiter on headphones. A couple of folks indicated that they needed the limiter on their brand machines, particularly those with high volumes and/or different tone I.D.s. One Tesoro owner said he didn't think a limiter was necessary on his Tesoro. My Tesoro Cortes does not have tone ID. It is a Christmas present (bought it myself, but my sweetheart will wrap it and I'm supposed to act surprised), so I have only played with it on the counter top for a few minutes to make sure it works.

My understanding is that the more the sensitivity is cranked up, the fainter the signal that can be heard. Sounds good, but I don't want to have my hearing blown away by a strong signal either. What do fellow Tesoro owners think...do you prefer/need a limiter on headphones with the Tesoro?

If you are getting loud , sharp signals , kiss your hearing good by..I am planning on buying earphones for my Vaquero, the Silver does not need them and would like to know what earphones have some sort of upper limit switch or control.on them..Cordially Nad

I've got 5 Tesoros and 2 whites and as long as I set the headphone volume at a comfortable level to begin with have never needed, nor wished for any kind of limiter. The only possible exception would be on the older umax series where the long tone indicating battery condition is very loud if the headphones are turned up full which only happens if the knob has been bumped or changed to full volume before I start up.

Joe,
The link has a general article about hearing loss and some information about sound level versus listening time. At the end of the article it has a lot of references, some of which will have a lot of detailed information.

Nad is right that if you hear a lot of loud sharp signals, you will hurt your hearing.

I worked on a project about 8 years ago that required a specific headset limiter. The problem was that the limiter was customer specified and external to the head set. The actual limited sound levels varied a lot depending on headset model used. To meet what the customer said was their intent, I had to specify a headset and calibrate each limiter to that headset model.

I did a google search for volume limited headphone and turned up not much really useful.

Many of the headsets available have volume adjust.

One thought:
Lay a soda can on the ground and set the volume level so you are comfortable hearing the detector beep and pinoint on the can, then don't increase it.

I would reccommend that you get a pair with a limiter switch such as Sunraypro golds , I got some killer B optima's with dual volume also some single cup stingers , and a pair of SunRaypro gold .....these headphones work great on all 3 of Tesoro detectors with the exception being the Tejon , the only pair that are suitable that give a nice comfortable lowest volume setting on the Tejon are Sunraypro golds with the limiter switch engaded , I dont know why but my Tejon has a more powerful volume than my other detectors..........and having phones with the limiter allows for a much lower adjustment in volume

Hay Joe,

It doesn't hurt. It may help.

I think tha most important thing

is to be able to change tha cord.

That's what I'm looking for if I buy

another set.

Joe, the Ratphones have built in limiters.

The Jimmy Sierras I had a few years ago had the limiters also, they are made by Detectorpro I have heard.

mea culpa. I shouldn't rely as much on google searches.

Sven taught me that there are a number of headsets designed for metal detecting that do have limiters.

From the Sunray web site I will add what they say about the the limiter on the Pro Golds: "Limiter results will vary from one detector model to another." I would think that applies to most designs.

As trueblue indicates is his experience, I have to turn the volume down when I take the headsets off any of my other detectors and put them on the Tejon.

I bought a Cortes during Christmas 2007 with headphones. The headphones sent with mine have a small rotary volume control on each earcup, (I'm unsure what your calling a "limiter").

The knobs always get bumped during transport but are easily adjusted and equalized for different hearing levels in each ear in about 5 seconds, (sirens take there toll over the years).

I keep the volume on my headphones as low as possible after finding it gives you a headache listening to the same tone at high levels all day, plus the earcups eliminate a lot of ambient sounds so you don't need a lot of volume. But always keep your eyes peeled, where I usually go is the older (da hood) areas of town, Old copper and silver to be extracted there.

When I first got the Cortes I thought it was biased towards only finding copper pennies (seriously), It seemed thats all I ever found, but not the case at all. "If its in the ground and you wave the coil over it, it will beep" and the display is usually pretty accurate also but can be fooled by some junk, I dig a lot of pulltabs for various reasons.

Get volume controls you'll be glad you did. I have 1 pair with full ear cups for cold weather or really noisy areas. The pair I use most are behind the neck type with small foam ear pads, much cooler, and you can hear whats going on around you.

Hi all,
Since I see what look like a couple of different interpretations;

Volume control does just that, adjusts volume level louder or softer but even at low setting can still have very loud peaks. May not save hearing.

Volume Limiter will try to keep the volume peaks from going above a certain level no matter what the volume control is set at. Hopes to save hearing.

I agree with Tabdog. Every set I ever had fail was due to the connection going bad where the cord connects to the earphone. Alot of stress on that area. Maybe the Grey Ghost NDT would prevent that?
