GS5 POWERLINE GOLD

[Eric Foster]

Here is a picture of some nuggets recently found in Australia on a site with overhead power lines.

The finders comments are - Photo of 6dwt of gold found with the beast (GS5B) under power lines using a Minelab 11 inch mono coil. The BB's signals were very very faint and 4 inches wide. The gold was sharper. I dug very little ferrous scrap.

Here are more finds from the GS5 user in Oz, with his comments.

Had another bash at my noisy and trashy site for 10 pieces totalling 9 dwt. It was quite prolific from a relatively small area below the crest of a deep alluvial run along a ridge. By the number of discarded 9 volt batteries it had been detected in the VLF days. But certainly not detected by SD/GP because of interference from power lines, Telecom and road traffic on a nearby main highway.

With the GS5 there are no false hot ground sounds. If there is a faint murmur it

And like you I dug very little iron with the GS5. It truly is one of the best on the market today.

Hi Buttondigger,

It's not me finding the gold. I'm just passing on comments and pictures from a very recent customer in Australia, who is doing very well in noisy and trashy areas. For obvious reasons, he wishes to protect his identity and hunting location at this point in time, so I am doing proxy posting.

Awesome pics Eric. Thanks for sharing the results. Looks like the GS5 is one hot machine!

"If there is a faint murmur its a target"...

How interesting.. I wonder what Range Control setting our Aussie mate is using??

My experience using my "old fashioned" GS5 is to have the Range Control set at almost maximum with the threshold on the cusp of silence, which gives me tremendous sensitivity to nuggets as small as 2.1 grains as well as finding #4 lead bird shot and the somewhat larger iron shot as deep as 3 inches...

Good sharp signals on the above by the way.. It almost feels like I'm back to using the old VLF on those bird shots.. I still would like to know his RC and Threshold settings if possible. That shouldn't be giving away too much I think..

Cheers, - Jim -

Sabra Jim,
Our Aussie prospector is using the following settings on his GS5,

Range control =full on
Volume control = 80%
Threshold = just on to minimum
He is however targetting areas with some or all of the following
Noisy mineralised ground
Interference present ie powerlines, telephone cables and' or the presence of a lot of ferrous/non ferrous scrap, all factors which maximise his advantage coupled with many years of experience esp with regard to areas where there is gold known to occur.
In the Australian Goldfields,all the small towns have powerlines and comms cables running right through the adjacent goldfields, leaving many areas, difficult to detect thoroughly, because of the resulting interference.(he is doing something right)

G'day jackg,

Thanks so much mate for the info.. It looks like I'm not too far from those settings when using my unit, which gives me more confidence.

Yes powerlines and interference areas are "duck soup" for the GS5/5B and there are many more of those areas in OZ compared to N. Nevada where I mostly hunt..

I sure wish I would have had a GS5B when I was in the Leonora/Laverton and points north area in 2000.. If you will PM me, I'm sure I can put you on some serious gold using the GS5B..

Thanks again mate,

Jim,
I have sent you a PM in response to your last post in this thread.

Hi All,

A further report from this prospector -

Tried along a too heavily grassed serpentinite/dolerite/slate contact yesterday for a 0.8 gram piece with the GS5 using a minelab 11 in mono. I had previously missed this and other targets with the 3500. I was surprised at the number of non ferrous targets I found in areas gone over carefully with the 3500 & 11 in DD coil in mono.

Ground signal changes in such a situation would be very severe, when going from slate, which has a sedimentary origin, to dolerite, which is a coarse grained basaltic rock, and then to serpentinite, which is a metamorphosed olivine rich rock. The prospector reported that the GB had to be adjusted more frequently when passing over basalt/dolerite boulders, but he did not encounter any false signals from such ground.

Eric.
