DOES IT EXIST... A PI DETECTOR THAT GOES MORE THAN 1 METER DEEP????? :ban::ban::ban::ban::ban::detecting:

When you say 1 metre deep.....on what sized "treasure" target?
If you are trying to find typical coin/ring sized targets then 15" is really about the limit.
You will hear many "claims" of much deeper but I for one refuse to believe these.
15" is it for "clean" coin/ring sized targets....."clean" meaning no huge green crusty coins which will give deeper results until disturbed.
Just as I don't argue with my wife, I don't argue with the laws of physics
Hope this helps,
Tony.

PI's are better in highly mineralised ground....looking for gold nuggets or deep relics or beaches loaded with black sands. Some
Multifrequency VLF's will perform as well as PI's in typical beach conditions (free from black sands).
The advantage to PI's over VLF's diminishes as the ground becomes less mineralised.
It really comes down to what targets are you hunting for and what type of ground are you hunting on...you then have to decide what your best detector will be...?

Thanks TONY 
There's dozens, could be even as many as 30 at the moment that will exceeed 1 meter on a LARGE object if larger coil sizes are used (40"x40" or above).
Ones I have tried or seen working are the Proton 2, Goldstinger, Megapulse III, Ground Pioneer 4500, Detech SSP's, SDP 2014a ?, Lorenz, Stinger 2, Pulse Star II.
Some,like the Pulse Star, have ferrous discrimination that can be switched in or out thats based on size of the ferrous. Others (Detech for instance, have some coils with built in magnetometers).
There are now also a few machines coming on the market that try to bridge between conventional VLF machines and Pulse. The Grizzly "Twin" is one of these. It combines an Induction balance machine that can be switched to being a conventional P.I. by swapping to a 38cm coil or a hoard hunter by swapping to a 1m X 1m coil. Only problem with this is I can't find anyone whose used one and prior to this I didn't regard Grizzly as making innovative or top range detectors. Deepers came out with something similar a few years back. In the past the drawback with this sort of approach was that though they worked they never performed as well as a dedicated coin machine or a dedicated hoard hunter.

Brian, I looked at the Grizzly detector that you mentioned and it appears to be a high end looking machine.
Is this company known for making any other electronic type devices?
I'd sure like to see one in action as you stated in your post. The cost was about $1386. USD, which puts it up there in price with some
of the other known manufactures out there.
I suppose if it worked as advertised it could be a possible bargain even at that price point.
All the best!

The cheap machines sold under the Grizzly label in the past are I think China specials sold by other dealers as the MD 3009 and 3010 or Lander XD50 and XD100. So not to hot though they are at a low price point. Could be that an importer is buying machines and has decided on having his own brand of Grizzly and is now going high end. This new machine certainly looks o.k. but does it deliver ?
The Deepers attempt along these lines works so its not new ground.

Brian, Thanks
Hello Oscar,
Before say that .... test yourself , never the two box Geminis go to 6 meters ....
i made many test with two box in our test field ....it did not detect a 200 liters tank
at 3meters deep
and with a very fine adjust can catch a gallon tank at 3 feet !!!!
It is really easy to make a test take a shovel.... make a hole deep enough ...put your target and fill in again the hole
....but not many people make test!!!! to really check the penetration power of a metal detector....i do not know why???
And... for a PI detector with a 8 inch coil .... it is very easy to detect a gallon at one meter in mineralized soil !!!
in the photos with a 16 inch detection easy of the target the drum at 3 meters and see in the minilogger from Tim
Alexis.

Tony, I had to smile at your closing remark.
Like you I don't argue with the laws, but rather with those who often miss-interpret or wrongly apply their understanding of same.
This forum at least attracts those guys who have a technical curiosity or back ground knowledge sufficient for them to diplomatically discuss different perceptions on matters related to detecting.
How refreshing to share thoughts with Eric, whom I've been aware of for many years and wished that I may have had the opportunity to share, (tete-a-tete) concepts and theories.
Many have been the visit to Oxford to collect my daughter during 'Uni-breaks', and thinking to myself, ' Where's Eric's QTH?' Now she lives in Australia, and when I visit OZ, I jokingly threaten to head off into the bush and do a bit of gold searching........Ah well...I can dream.
We stayed in the old home of the guy who in the 1840 owned the gold mines outside of Launcestone (Beaconsfield?), for a week in 2008, during a tour around Tasmania.

The visit to the adjacent museum was a great day out.
Eric, I think you've done a bit of touring around Australia...ever been detecting for the odd nugget?
Best wishes to all the lads and lasses on the PI forum.....Matt.

Hi Matt,
Where are you now? I've moved around a bit, but Oxford is home at the moment. I hope to be back in Australia later in the year to do more testing in their highly mineralised ground. I haven't yet found anything to beat it for magnetic susceptibility or viscosity.

Hello Matt,
Yes, this forum is great. I'm not on here as much as I used to be but I do login every now and again.
I'm armed with only basic (but sound) knowledge of PI's.
I don't like to respond to simple questions unless I'm confident with the facts.
I have Eric's Goldquest SS, which I still use. I have a VLF detector as well as a TR machine for water hunting.
Back to the UK and USA this September.....I'm resisting the urge to get another PI from Eric, especially with the current exchange rate !
....Eric, are you still making any DS3's or similar ?????
Regards,
Tony

Evening Eric.....I live up north, in Cheshire.
Despite having Chester in the principality, it is a relatively poor area for detecting, compared to the Eastern side of England.
The 'best' land is either built on or owned by the unyielding Duke of Westminster. (Only joking Duke if you're reading the PI forum).
But we northerners are a stoic lot, and being raised on fish and chips, and rabbit stew and dumplings, makes us a contented tribe.
Even when we haven't found a 'penny for some chips' we will make do with just the free, left over 'fish-batter.'
Did you ever have fish-batter-bits from your local chippy, Eric?
If only I had a metal detector when I was a lad, (Weren't 'invented' then....) Now I have literally thousands of pennies in many plastic buckets, stowed away in the vast overgrown corners of my estate.
I've never sold a single item that I've detected, for they each represent priceless, irredeemable, happy times of enjoyment.
I did bury a 'hoard' of copper coins in an earthen ware flower pot, in my garden, many years ago. It is sitting at 2 feet six inches depth, and the pot is 5 inches tall.
So I can test every detector that passes through my hands.....but no ordinary ID or pulse has honestly located it yet.
I do have your 11 inch coil and Goldie, but the battery pack needs replacing and I also think it needs Eric's tender care, for it had been 'fiddled with' when I bought it second hand.
So if you ever 'come out of retirement' , I would love to ship it back to its place of birth.
Hopefully, it is refurbish-able.
An old customer of yours and passionate Foster Pulse owner, (Danny from North Wales), still prefers the the sea shore and your 'modified PI', where he can do some real detecting.
Time to close this post Eric, for the sun has set, and the ash is hiding the moon....not really.....but I'm wondering what is the permeability of that Icelandic 'talcum-powder'?
Good-night....Take care....Should we meet on the crowded quay at Sydney, I'm the good looking one, eating an Eccles cake and drinking cider.......Matt.
