Im a beginner and am hunting on the sand with my Vaquaro. With small pieces of rusty metal and with a coin i get a double sound .Have discrimination set a little below below pull tab. Tried the sensitivy on 10 as well as 6 no difference.I DID THE TEST FIRST WITH THE COIN THEN WITH METAL NOT TOGETHER. Thanks
 
I don't know about the Tesoro's but my experience with machines usually indicate a double crackle bleep as a nail, sometimes screwcaps, and also off the rust halo in the ground. Changing settings on the machine may or may not change the audio sound of the double bleep. Then I have machines that will give these targets as a single tone too. After awhile you'll figure what the machine is telling you. I normally discrim out the nail and a little into foil region - up to the tab region depending how each area I'm hunting is going. I've had wire do strange things also.
 
Hi, there are some variables you haven't mentioned. First- what type of coin. If its a corroded zinc penny your machine may be trying to disc it out. Also, is your machine GB'd correctly? I know my Cibola will do the double beep on a real shallow or surface coin, but not as deep as you stated. There are many situations to which a machine can act differently, so keep trying and testing and you'll figure out what its telling you!!!!
Good luck

Here is another possibility. While I'm not much of a beach hunter, I went to the beach yesterday with my Tejon because the ground is frozen everywhere else. I don't know about the sand you were in, but part of the beach I was on was black sand under the normal looking sand. Even though I constantly ground balanced and lowered the sens. it gave my detector fits. The rest of the beach wet or dry was fine as long as I GB the machine. Have you had the same problems in dirt? I don't. Just a thought.
 
William, this can also indicate two very shallow targets close
together.
Try this:
1.. Change your swing direction around to 90 degrees from your
double beep swing. This can better separate the signal of 2 items.
2.. And/Or, change the mode temporarily to all metal, lift the coil
a few inches higher over the signal while swinging. This can narrow
the response from 2 conflicting targets and the A.M. mode will
help to better define the targets as opposed to the disc. mode
trying to reject a strong signal while trying to accept another
nearby.
3.. If you have one, change to your smaller coil which is better
at target separation in trashy ground.
These have worked for me with similar indications and, this effect
can also occur with any detector, not just the Vaquero.
Happy Hunting!
