Lord of the Rings! WoW! I have a question for ya, where you write " ground balace out a nail" is to have one under the coil while performing the GB? Thanks JohnE, great tips

 

[John-Edmonton]

Yeserie!

 

[Hank68]

Thanks!

Yeserie!

Just curious, why wouldn't you just "Iron Disc" the nails out and, depending on what targets your focusing on, set the GB to be optimized for either high or low conductors?

 

[John-Edmonton]

Yes, you can disc out the iron, thereby removing the audio, however, by retuniing the detector, you are even making it more sensitive to other targets other then iron. Unfortunately, by doing so, your are changing the accuracy of the discrimination settings.

I see what your saying. So this would be for extreme situations where there's little or no ground that's not affected by nails, is that correct?

 

[ToadWhisperer]

After going back over your original post I see that you were referring to extreme situations.

 

[John-Edmonton]

That's correct. I have hunted homes where the ground around the house was just littered with roofing nails. This might be a place to consider ground balancing them out.

great tips ! happy hunting

Hi,

Ground balancing out iron targets has been my credo for years.

It is a very helpful technique indeed on "iron carpets".

It has, however, two side-effects.

It can first disc ou (I should write "balance out") thin gold.

And it can make steel cored coins (canadians, eurocents, e.o.) reading as high as common, normal "clad".

This last can be a blessing in disguise as far as coin spills are concerned, as those pesky steel coins can mask an entire spill.

Chances are, if you are discing out the iron, you are probably searching for older silver/copper coins. And you will probably miss the gold too.

So, if my goal is nuggets I would be better hearing all iron targets? Would there be any problems in discing out targets in the low twenties and below and then use the "iron audio"?

 

[ToadWhisperer]

Sorry, didn't realize you were still discussing heavy nail areas. Ignore my last post.

 

[John-Edmonton]

When searching for gold, I would manually adjust my VDI numbers higher, to increase my sensitivity to a lower conductor. I would then hunt using my iron audio on or off depending on how much iron there is.

[size=large]Manually tweaking the ground balance can in fact get you a little more depth. After ground balancing the detector, if you lower the VDI numbers, you should get increased performance on higher conductors like copper and silver. If you raise the numbers, you should get improved performance with lower conductors, like gold, lead and some small iron.[/size]

Good luck! A lot of these tips aren't found in manuals. They are learned in the field and should be shared with other Garrett users.

 

[Hank68]

I personally thank the ones who has shared your knowledge cause it doesn't come cheap to buy the machines and learn it! Double thumbs up!

 

[John-Edmonton]

It should shorten the learning curve and hopefully prevent people from getting into the which detector is deeper. As I have mentioned many times, which detector really can't be answered, as it just depends.

 

[Hank68]

I had a short hunt @ my inlaws yard, and I lowered the GB # like JohnE shared here, and I was killing the coins and the zincers were popping out dimes were loud, and my sniper coil was great spot on! It has shortened my learning curve to run it at peak performance!
