Listening for the right noise xterra705

[LC76]

So i was hoping someone might be able to help me out.

I have got about 60 odd hours on the X-Terra 705 now but all i seem to find is bullets.

Today was frustrating to say the least....this is from today.

This is in the whipstick near Eaglehawk.

So question is am i listening for the right sounds or am i doing this wrong?

Those bullets are copper coated to i think .......Full metal jackets? Army?

Best thing to do is get a few various targets - gold ring - silver coin - copper coin - bullet - pull tab - bottle top - and bury them all.

Get the detector and listen to each sound - dig a bit but not enough to uncover the target and listen again - note the numbers for each target type and away you go ...

Those are massive slugs too!

Are you digging particular sounds or all targets?

You need to dig all targets if you want my opinion.

 

[Nugget]

My advice is to buy a few various sized gold nuggets off eBay and run them past your coil at various depths / distances. Doing this will give you a basic understanding of where certain sized gold (nugget) targets might sit on the TID scale as well as what they sound like.

I haven't used a 705 but in the example of the Garrett AT Gold, small gold nuggets register quite low on the TID scale, so to a coin and relic hunter this would generally signify a trash target and could possibly be overlooked. A few test pieces will take out a bit of the initial guess work.

Theres no taking short cuts unfortunately.

You got to be careful if working off the digital screen
As well. Targets at different depths will give different
readings and will also sound different depending if
They are buried shallow or deep.

Dig all targets and your bound to find some goodies.

Sometimes the target you think you should not dig
And ending up digging will surprise you.

Hope this helps.

Thanks for the advice guys.

Also sorry forgot to point out its the gold pack X-Terra 10" x 5" 18.75 coil.

Yeah i have been listening for the high pitch trill kinda sound.....same sound lead makes and same sound that my Fiancs gold ring makes.

But also did some panning in a dam and got three tiny specs.
I waved them under the coil and didn't get a sound until i turned up the sensitivity to max(30) but even then it was barely audible.

So should i be listening for the really quiet sounds and not the high pitch squeals?

Gold rings don't sound the same as gold nuggets. As Wolfau said, it's best to dig everything when gold detecting.

Dig all targets is my opinion.

Not sure how the 705 works in reference to khz.

Generally the higher the khz the more sensitive to small
Gold and the more shallow it will detect.

So if you want your machine to zap zap on those Tiny
nuggets you need a coil about half the size of your
Current one running the same khz which is around
18khz.

The question you need to ask yourself is what size
nuggets do you want to target?

If its the tiny ones you need a smaller coil running at
High frequency. Not sure though if one is available.

Sorry Nugget, did not mean to reply over yours,
Just trying to help.

Here is what you need if you want to hear the small
Nuggets like you have in your photo more clearer.

Not sure though how hard the 705 hits on very
Small nuggets.

http://www.minelab.com/aus/products/consumer/accessories/coils/6-double-d-18-75-khz-coil

If you want to search for silver coins then go with a low
Khz coil because they hit harder on silver eg around
2.5khz to 3khz.

Just remember to dig, dig, dig.

 

[LC76]

Ok looks like its time to harden up and dig dig dig lol.
I might need a lighter pick lol.
Mine is home made and a bit heavy....nah i'll just grow stronger....a huge left arm lol.

Thanks again guys i appreciate it.

Are you running in Prospecting Mode when looking for gold? The coin mode is much less sensitive, even if you're in All-Metal.
Most gold will give quite a soft response until it gets quite close to the coil. Definitely need good headphones.

Yeah prospecting mode usually at "10 - 15" sensitivity, with headphones threshold at "4", factory discrimination "5"
And cheapish headphones.

So sounds like i need to listen for the softer sounds not the shrill high pitch ones.

This depends on the machine though.

My old tesoro used to zap zap over a .2 grammer.

The same goes with the GMT.

Just a question though. If a 1 ounce nugget is buried at
An inch? Will the 705 still give a soft response?

I would be digging everything because targets are deep
And shallow and these all sound different. This is my
Experience using a few different machines anyway.

 

[Goldtarget]

Just to emphasis what nugget wrote the the id on nuggets will be alot lower than a gold ring as such. If your digging lead you're in the ballpark. The rest is a combination of luck putting the coil over something large enough and shallow enough to register, and refining those few things you can control as the guys above have mentioned. Hang in there mate it will come.

LC76,

I have the 705 and 3 coils, the concentric 9" - 7.5kHz coil is intended for coin and treasure. The 10x5 elliptical 18.75 kHz coil is intended for use in prospecting mode and more suite to finding gold in the Whipstick. That's not to say the 9" won't find gold, but horses for courses eh......

I am yet to use it for prospecting as I normally use the 5000. I also have the 6" 18.75kHz for the small stuff. The 18.75kHZ coils are DD.

I was talking specifically on the 70/705. Yes of course the big one's will scream, but how many 1 oz'ers are sitting at an inch?
Yes most of the US units have the zip zip sound, the Minelab's use the Vco style or modulated audio.

 

[Guest]

Thanks for replying Nenad.

Thats the point though.

If someone is looking for a mellow tone And there
is a larger nugget and it makes a different Noise it
will be missed hence why i say dig all targets.

A day or so ago a 2.5 gram nugget was found by a
Vlf only buried at 3" so nuggets are still about.

I personally love the zap zap over target and its why
I only have used US made machines besides the 3500.
