Steve,
I (and apparently others) distinctly remember those ads stating the SD (whichever one) would detect "match-head sized gold nuggets at up to 3 feet deep" or some such nonsense. Those ads were within the context of Minelab advertising slicks (copyright advertising materials)..... there was no doubt about that.
Is it possible those Minelab ad slicks were, shall we say, "enhanced" by one of their authorized dealers or distributors ? I guess that's always a possibility, but I know what I saw with my own two eyes. That ad was floated around the internet prospecting forums several years ago. I may still have it in my files somewhere, and if I run across it, I will be sure to post an image of it here. But it does (did) exist.
Regards,
Ralph

yes Ralph I know there`s more to it than battery size but to get that battery life and to claim that it has the performance of an SD/GP it must be a very effecient unit wonder what current it draws.

Hi Ralph
Looks as if my reply on the finders forum disappeared into the ether. What I said was that a mob in the <IMG SRC="/forums/images/flag.jpg" BORDER=0 ALT="USA"> called Accurate Locators put the adv on their web page. At the time they were selling witchcraft machines such as long range locators and other questionable technologies. It now appears as if they are selling legitimate products that work. This company has absolutely no connection with Minelab other than that they were selling Minelab detectors. Here in Australia we have legislation that protects consumers from stupid or untrue advertising and there is no possibility that Minelab or any other company could get away with making ridiculous claims about their products. It is not possible to sell long range locators here in Australia because of this legislation.
Cheers
Steve D

Now there is something we agree on Steve ! 8^) Long-range locators are mostly hype, black magic, and a truck load of wishful thinking. I've seen a couple of guys "using" those things out in the Arizona mountains, and just had to smile at how they really believed they were going to find a big gold strike with those piles of parts and plastic. In every attempt at a "demonstration" I've ever seen of LRLs, with a good sized chunk of gold previously buried nearby, all the operator could do was make excuses of why this and why that, but they never found a thing. Not even a kilo of gold buried within a few feet. There is a certain company here in the states that still sells that junk, and only hurt their own reputation in the process.

You have got to be dreaming,with a post like that stating that minelab SD/GP will only find 2.5dwt or larger is a joke,here in Australia there finding small peices down to 0.1 gram.

No offence but re-read the last two posts. We are talking about ground conditions.

The Goldquest SS draws 70mA from a 12V AA battery pack, but its range and sensitivity is not that far short of an SD2100/2200, using the same size coil. This is from tests done by Reg Sniff on using the Goldquest as a nugget detector. The Goldquest does not use energy recovery but is just a different design concept for the transmitter/coil circuit.

The SD/GP will find gold on quite or hot ground,makes no difference,that was the reason that prospectors waited for many weeks to buy them when they were released in Aust .

You can`t beat an SD/GP in highly mineralized ground no hot rocks ext..but the GMT and Goldbug will find much smaller gold in quite ground.

Garrett couldn't find a pig in a poke!
Sorry folks, but I think they're getting desperate for sales, either that or they're using the same ad agency as Minelab!
96 Frequencies...BULL! Garrett don't have the know how. Anyways the harmonics content of the signal transmitted by a PI extends to 1000's of frequencies. Trouble is, as you reach the higher orders, the amplitude isn't worth spit.
If you start with a 15V peak-peak square wave, by the time you get to the 20th harmonic, you're down to something like 10mV, that wouldn't even penetrate a piece of cardboard.
So don't be taken in by another load of manufacturers hype. NO ONE has YET produced a TRUE MF machine, and NO_ONE will for at least two years due to the costs involved.

Just one other point to note.
If Garrett are claiming 96 frequencies and the fundamental is 600 pulses per second, then at a spacing of 600Hz, the third harmonic would be 1800Hz, then 3000Hz etc...Do the maths with an ODD multiplication factor each time.
As the FINAL harmonic comes out at something like 172,800Hz (600*3*96).
Now as the capable Robert Hoolko would point out from his project on the Geotechnology Tech forum, to get the sort of angular resolution and depth required to meet the claims for the "Infinuim", the engineers would have to use 24 Bit Analogue to digital convertors.
Since the Nyquist of 172,800Hz is 345,600Hz, and since a convertor to "do the job" hadn't been made by ANYONE at the time Garrett started their design, I think I prove my point.
Of course, they could be using high amplification, with a lower resolution convertor, or "laddered" FLASH convertors, but somehow this would appear to make the machine too expensive to produce.
One final approach would be to "bounce" between two convertors, this would give the effect of doubling the sample rate, and also oversampling techniques might squeeze a bit more performance in the signal to noise ratio depertment.
