Compadre - single beep vs double beeps vs scratchy

[pkrska]

I would like to know what the difference is when hearing a double beep compared to a single beep when using the Tesoro Compadre? Sometime I get a double beep but it's not repeatable. I found foil and pennies with the double beeps.

If a coin is on it's side compared to lying flat, what kind of different beeps would I expected if any?

I am trying real hard to see if it's a short beep or a long one but sometimes I can't tell. If I go slow it just beeps, and if I go faster, then the beeps are faster but I am still trying hard to tell the difference of short and long beeps. Doesn't seem to be.

I also heard that scratchy sound. Kinda happens at the end of the swing. Solid beep in the middle and scratchy kind at the end. What's the scratch suppose to mean? Can it hit on a gold ring and be scratchy?

I have had dimes double beep alot at surface to 1 inch level, quarters on the other hand have never double beeped on surface for me but again we all detect different soil conditions so to say my example should be the same for you would be wrong to say.

It really depends where the discriminator is set. The Compadre is razor sharp. So if at iron nail disc., steel bottlecaps will break up as well as larger iron because it is so close to the set point. Right in front of the "foil" will rid you of teeny pieces of foil but accept larger pieces and you will hear that little scratch on the end of the signal. For me, using the sizing technique of the signal ALONG WITH any discrepancies is more accurate. So a quick, short signal would be something like canslaw or a small piece of foil, but a coin, as well as a tab, would sound-well like a coin! Using it will tell you more than anyone can explain. And don't forget location. If I'm in a tot lot where diggin's just a matter of kicking back the pebbles or chip barks, EVERYTHING gets dug. A fine gold chain sounds just like a small piece of foil. That's why I went from trying to predict my finds to "beep-dig". You will find posts, if you look long enough, that go like this: "I was going to pass the target up BUT SOMETHING just told me to dig .....and I'm glad I did"

What is the configuration of the signal coming off the coil.

I have a picture of 2 coils. Would the signal coming off the coil be like A or B or other?

 

[digitaltim]

I've seen double beeps on shallow targets.. A beep for each edge

Scratchy- could be trash.... Could be a good target next to trash

As slingshot already stated: if you can get a solid, repeatable beep its a good idea to just dig. Then you'll know why it sounded that way

 

[Topo]

as slingshot said, it depends the discrimination you are using and it will depends the levels of mineralization in your area

at the places I use to go I always run mine bellow foil, I remember I once heard a scratchy sound that I almost missed, it was a 16 century coin at 5in depth, after that episode I always dig, dig and dig

A single or double - or even a multiple - beep can come from several causes. It can also depend upon the Discriminate acceptance level.

First, if a coin or similar target it positioned too close to the search coil, you can get a double or multiple response. Most Operators Manuals suggest searching with the coil held 1"-2" off the ground. There are several reasons to do that, and one is that it can help eliminate surface-target response disturbances.

Second, if the Compadre has the Discrimination set at the minimum setting (which is a true ED-180 or all metal accept setting) and you sweep over an elongated target, such as an iron nail, you can get a double-beep if you sweep over it lengthwise, but a single-beep if you sweep across the elongated target.

So, coil-to-target closeness can be one reason, and another can be target shape and position, such as the elongated iron nail.

If a coin is on it's side compared to lying flat, what kind of different beeps would I expected if any?

If the coin is stuck in the ground so that the 'edge' is pointed front-and-read as you face it and you sweep across it, you will get a double beep (usually, depending upon distance from the search coil). If you turn 90

Neither of your sketchings are correct. Not Fig. A, with a familiar 'V' shaped suggestion, or Fig. B with the varying lines going vertically down from the coil.

For years, decades, actually, we read so many people mentioning the" 'V'-shaped electromagnetic field" or the " 'V'-shaped signal" and then we see some manufacturers tease the readers with an assortment of arrows that point downward from the search coil. All of those are incorrect and Do NOT describe the electromagnetic field that flows around the Transmit coil winding.

We won't get into Double-D coils at this time, but I will say that if you use your imagination a little, and you are looking at a side-view of a round-shaped concentric coil, the Fig. A shape is not exact, but is sort of similar-to the functional portion of the generated EMF.

Not the shape of the transmitted field, but a close example of the portion of the much larger field that is going around the Tx windings, and is having a reaction on the Rx coil and circuitry interpretation of the responsive portion of the search field that was generated. That is, the smaller and weaker targets, or those that are deeper, are going to have a smaller and narrower reaction area at a greater distance from the axis of the center of the search coil. Shallower targets will seem to have a larger response area due to the size and tight line of force of the EMF that is closer to the search coil.

Heck, it's only a simple, 1-knob Compadre. Just set the Discrimination level to barely reject an iron nail on top of the ground, then go hunt. Don't fret over all the science part of detector design, just go use them. As you move up to more sophisticated makes and models, learn the basic adjustments and features they provide.

Have Fun!

The reason I asked about the coil so that I know what I am up against when I hear a beep. Sometime the beep sounds like it came from the front or side of the coil, other times it sounds. like it's from the middle of the coil.

Without me know how the coil actually works, I am going in blind and guessing everything. There are times when I dig and find nothing eventhough I was getting beeps. (ya, ya, I know, get pin pointer)

Try raising the coil till the signal's at it's weakest. lt should then be in the center of the coil

Wow thanks to all for sharing . This info is great.

Todd, I hope you don't mind me butting in and I'm sure Monte will add. Even the sweep speed depends on the soil makeup. The best way I've found is to go to the roughest soil you know and when you get a short, quick signal slow the sweep down and find the best speed to get a good signal. Then you'll always know for yourself the best sweep. In tot lots with bark chips and hardly any mineralization, I can FLY with that little thing and it goes DEEPER with a faster sweep speed. It's only when I get in the mineralized ground I notice the "almost" signals.

slingshot........Don't mind at all, in fact I encourage others to jump in !

Don't get me wrong, I do appreciate all tips, even when described in general terms, but prefer detailed instructions whenever possible. For example, what steps do you take to determine if the soil is "rough" as you put it ? I assume by rough you are speaking of high mineralization soil which conducts electricity well, but due to the resultant low matrix to target conductivity ratio, makes target detection difficult. On the other hand, when the soil has low mineralization and low conductivity, the conductivity of any metal target stands out in comparison and is easy to detect. Of course, "easy" depends on what detector settings are used for Sensitivity and Discrimination.

Thanks and I look forward to your reply.

I have a good idea , try video taping 10 or so diggs and the sounds the machine makes , then watch them back. This will train you on what sounds to expect with a coin and trash?

Their somtimes is no good way to determine what you may have until you dig. But then you dig a scratchy tone and its a gold chain! Then your smiling!

One Mississippi .. Two Mississippi to cover about a 30" side sweep, and add maybe an extra breath after that to cover a 4 foot path. It might also depend on how slow or fast we can say Mississippi.

As I often state, in very favorable conditions, such as many playgrounds with 8" to 12" of loose wood-chips, you can often use a faster sweep speed. In ground, and especially in a more dense mineralized environment, the 2-filter models just need to have a slower sweep speed used. The secret for anyone is to learn the particular detector, with the search coil that is mounted, and in a variety of ground mineral challenges.

Locate an already lost and buried target. One that is about 3", at least, and especially 4"-5" deep. Sweep across it at an 'average' sweep speed. Then, once pinpointed, work over and across that targets at a slower sweep speed and note any performance changes. Then, use a faster to very brisk sweep speed. Odds are the faster sweep will not be so impressive, if it is too fast.

Yeah-mineralized soil. And if you decide to try Monte's method, whatever you do don't say M-i-crooked letter, crooked letter, i, crooked letter, crooked letter, i- humpback,humpback, i.

 

[slingshot]

Sorry, I got carried away with a little humor (yeah, I know. Very little) You just have to observe your signals-especially the partial signals and see how they react at a slower sweep. Man, don't let me take away your fun-and the fun is learning by doing things yourself-once you have the general idea. I'm still learning and that's why I read everyone of Monte's posts I can find. But, in general, the slower you have to sweep the higher the mineralization on GOOD targets. You'll always get partial signals on some trash or target masking. Best of luck Thanks for reading.

Monte,

Thanks for the reply. That gives me a method to follow !

With reference to your statement I high-lighted above, I'm curious........how do you tell if a detector is a 2-filter model ? Does that have anything to do with the coil having two windings, i.e. a TR (Transmit/Receive) unit ?

Would I be correct to assume that the Tesoro Compadre is a 2-filter unit ?

U-da-Man Mr. Berry !
