Post  Argus Tuft on Sat Aug 15, 2015 12:21 pm

Greetings all,

Is it possible to successfully detect for gold under high tension power lines? If so, with what type of detector/coil combination?

I have been researching the question myself on the internet the past few weeks and found little firm information indicating the possibility or otherwise aside few chance remarks along the lines of, "Yeah the GPZ worked right underneath them" or "They blew the capacitors in my GPX from 50 yards away."

I do have a location in mind - it is moderately mineralised, shallow and comprised of weathered shale/schist (typical for ground HT power lines follow).

Any advice would be appreciated.

Welcome to the forum Argus Tuft Smile

Without knowing what/if you have a detector, i offer the following.

It CAN be done with a GPX (unsure of GPZ myself) using a Nugget Finder XP coil and adjusting settings to suit. I won't go into details as i'm unsure of your knowledge and don't wish to confuse you, however if you get a chance to look at Johnathon Porter's dvd of the GPX series (the one for the GPX 4000) it will give more details.

IIRC the 'blowing of capacitors" was on a GPX 5000 using a mono coil, but i am open to be corrected on this matter, as i have personally detected under power lines with my GPX4000.

Good luck in your hunt for the color.

Thank you for the information GGA.

I am not an experienced detectorist GGA. I would like to be able to detect under HT power lines and so that is a prime consideration in choosing a detector/coil. The current deal on the GPX4500 is tempting particularly given your note regarding success with the 4000.

I'll certainly look at the DVD you recommended and perhaps we could talk further regarding timings etc.

Kindest Regards,
Argus (Tuft)

The recent 4500 deal is terrific and if cashed up, i'd be all over it. That's cheaper than i got into my 4K for and a step up at the same time.

Settings & timings will vary from ground to ground and even down to the o/head lines and their emi output in different areas.

If you go down this path with the 4500, read the manual, then read it again, then read it a 3rd time and get to 'know' your detector, before you even go looking for gold. Find an area without targets and put a range of various different metals out to 'practice' with. By doing this, you will become familiar with various settings and save yourself a LOT of walking without a result. Additionally, until you become competent with the detector, you will NOT be walking over or away from ACTUAL Gold, and in the long run be further ahead of the game.

Happy to help where possible, but the difference in the two models is enough that only 'some' of what i can offer will be of use, and you will need to draw on 4500 operators to assist with certain timings that the 4K doesn't have.

Good luck with your journey.

Hi Argus and welcome.

For detecting under power lines just use a DD coil in cancel mode on a GPX machine.
I can't speak for how a GPZ works under power lines as we don't have power lines out here sorry.

Hi GGA,

Thought I'd ask a few questions on both your replies if you don't mind?

firstly, what does IIRC mean? and I've never heard of working near power lines damaging some ones detector so could you please elaborate?
For those of us who wish to be confused could you possibly go into detail regarding the settings?

On to your 2nd reply,
wouldn't it be better to test your machine in an area WITH undug targets? (obviously in a gold producing area) because then your comment "By doing this, you will become familiar with various settings and save yourself a LOT of walking without a result." would hold true as an area WITHOUT targets WILL produce no results. Who knows, he could possibly find a nugget or two while learning his machine.

Also, while learning we are always walking over and away from gold, even when proficient we still do, I know I do.

IIRC = If I Remember Correctly

As to damaged detectors, i was only referring to Argus Tuft's mention of it, i have no personal experience but the grey cells seem to recall a poster on a thread somewhere about it and those were the details i'm able to recall, sorry not to have any specific item i can link to. (In the end it may very well only have been coincidental to be aroung HV's at the time and was in reality a different issue????)


Which settings would you be after? 4K or 4500???
My settings are based on an XP coil and NO cancel, which is slightly different to how you suggest to set up under power lines, so of little use to those who use DD and Cancel.

On to your 2nd reply,
wouldn't it be better to test your machine in an area WITH undug targets? (obviously in a gold producing area) because then your comment "By doing this, you will become familiar with various settings and save yourself a LOT of walking without a result." would hold true as an area WITHOUT targets WILL produce no results.

Also, while learning we are always walking over and away from gold, even when proficient we still do, I know I do.

My advice was given with a newb in mind who can "practice" in his backyard on learning how his 1ST PI machine works and what different target responses will sound like. By 'without targets' , i meant where he was sweeping the coil and he could have his own selection of targets to try. Sorry that was too brief an explanation, but the OP is/was free to query if he felt he needed further info. regarding this.

Dug or undug, suit yourself, i was just trying to save the guy some walking....but we both know you are being contrary for contraries sake don't we Laughing

Lol...there ya go again, being presumptuous and contrary.  Tuna... we ALL do things different, and YOUR way isn't the ONLY way, do what you like, but no need to down on how others do their thing as long as their having FUN. It's only a "hobby" for most of us.....ymmv as a full time operator. But don't forget where you came from.... we all started from knowing FA and if fortunate, got "help" from those in the know. Rolling Eyes

I didn't realize this little thread was meant to be an A-Z of detecting.... Embarassed

Don't know what your issue with me is, but i'm done here. OP if you'd like feel free to PM for my thoughts. Wink

GGA  I apologize if my offering another suggestion has upset you, that was not the intent. And yes, the more suggestions however different the better. Then you choose what works for you.

Geez!



edit... when someone offers a different opinion than yours all they are doing is doing exactly what you're doing, offering an opinion. Nothing more nothing less.
It doesn't mean you're wrong and I'm right or visa versa, after all it's just an opinion, another way of doing something that works for the opinion holder.

If someone asks for clarification of your opinion it's probably just because they don't understand fully and would like to. I had no idea what IIRC meant.

It doesn't mean they are being contrary, I still don't fully understand what you mean by that (now I'm afraid to ask)

Don't read into something what isn't there!




2nd edit... I don't have an issue with you, I don't know you. Not positive but I think this is probably the 1st time we've typed at each other.

3rd edit...what does ymmv mean please? and it's far easier to find gold than it is to find an XP coil now a days! Very Happy

Addendum to above...apology accepted in the vein it is offered. I don't know if the OP is in suburbia or how close to goldfields he is, but i would hate to think he has to travel 100's of k's to get there..... without at least trying his machine to see that it at least works. I wasn't suggesting he become 100% proficient in his backyard, just a "teething" test before getting on "good" ground.

If needed for more concise or specific info.,... i am only too happy to give it, yet at the same time not to overload a newb with too much at once.

Forums are a bad/good place for info., but without writing a mini book, some subjects, to be understood clearly, need more than a two line thread response post.

I too apologize for taking your intent the wrong way and reacting as i did. (yeah, i get too precious at times.....sorry).

All good in the house..... afro  lol!

Mate the sdc2300 is a true "turn on and start detecting" detector and it`s not deep punching like the GPX or the GPZ but it works fine under powerlines

Nahhh, not my style. If i was to come for ya, it would be in your face and you'd know it, not cowardly or in an obtuse way. Glad that's not the case here though.

Gotta laugh, cos i went through the same symptoms when i first encountered it a cpl (oops, couple) of years ago on an RC (radio control) site and it has worked it's way into my keyboard habit. I'll work on K.I.S.S. (keeping it simple ...stupid(me) ).

Thanks GGA, Phoenix, madtuna, et al for your advice/contribution.

I have understood the acronyms as I have had someone younger handy to explain them as necessary.

It seems detecting under HT power lines, is not the near-impossibility my (admittedly scant) research had lead me to conclude.

There's not much sub 10g gold in the very shallow ground of the location I intend to detect - however I may venture to chase the same gold into deeper ground and so should afford some preference to a detector that will handle that transition competently.

Am I correct in my understanding The SDC will begin to struggle finding larger targets as the depth increases?

Is the Garret able to match the penetration I understand the ML 4500 achieves?

The 5000 and 7000 seem an overkill given the above. Right?

Hi again Argus,

 as some have rightly pointed out the SDC is a highly capable machine. It does however have its limitations on deeper stuff.

My experiences with the ATX is limited but I found it ungainly, not very user friendly and sadly wanting when testing it besides a 5000 on undug targets. How it performs under power lines I can't tell you sorry.

While the 5000 is no way over kill, the current deal on the 4500 is hard to beat. 

Cheers,

steve

+2 on the 4500 package deal currently available as based on MAP costings, it's a more versatile unit at about 5-800$ cheaper than a new SDC.

Good luck with your choice and the hunt, hope ya find heaps of color.

+1 SDC 2300.
Have found gold with it under power lines. Had to lower the sensitivity from my standard setting, and it has an annoying warble/wail to it, but once you got used to its rythm, it was ok to hear targets.

VLFs should be even more stable.
