I have a big Foot for my MXT. Everybody knows that the Big Foot is only good for a few inches, guess they never tried it on an MXT. Silly depth.

I was planning to sell the Bigfoot, but now the Arrow has spoiled the premium market...but now I don't care, with the MXT it is amazing.

Wonders of AI...notice how it mentions NOTHING about actual alluvial gold..

so, I tried again...

Notwithstanding Steve's having told me years ago that alluvial gold in Greenland is probably scarce due to glacial activity...I keep look around to find encouragement.

Google's new Bard, AI assisted search engine is fun to play with, so I had some fun just now.

So I asked..

is there any notice in the last 3 years of finds of alluvial gold in greenland

Yes, there have been a few reports of alluvial gold finds in Greenland in the last 3 years. In 2020, a team of prospectors from Canada discovered a large deposit of gold in the Kangerlussuaq region. The deposit is estimated to contain over 100,000 ounces of gold, and it is the largest gold find in Greenland in over 50 years. In 2021, another team of prospectors discovered a smaller deposit of gold in the Isortoq region. This deposit is estimated to contain over 10,000 ounces of gold. These discoveries have renewed interest in gold mining in Greenland, and several companies are now exploring the possibility of developing these deposits.

Here are some of the details of the recent gold finds in Greenland:

• 2020: A team of prospectors from Canada discovered a large deposit of gold in the Kangerlussuaq region. The deposit is estimated to contain over 100,000 ounces of gold, and it is the largest gold find in Greenland in over 50 years. The discovery was made by a team of prospectors from the company True North Gems. The team was using a helicopter to explore the Kangerlussuaq region when they spotted a large area of bedrock that was exposed by erosion. The team landed and collected samples from the bedrock, which were later assayed and found to contain high levels of gold.
• 2021: Another team of prospectors discovered a smaller deposit of gold in the Isortoq region. This deposit is estimated to contain over 10,000 ounces of gold. The discovery was made by a team of prospectors from the company Veritas Gold. The team was using a ground-based exploration method called induced polarization (IP) to search for gold when they identified a strong IP anomaly in the Isortoq region. The team then drilled a series of test holes, which confirmed the presence of gold in the area.

These discoveries have renewed interest in gold mining in Greenland. Several companies are now exploring the possibility of developing these deposits. However, it is important to note that these discoveries are still in the early stages, and it is not yet clear if they will be commercially viable.

If the cover is missing or the plugs which fasten it are missing or broken, you can make a simple panel with appropriate holes to line ump with the holes on the case. Then you can get some of these - Amazon has them. I also have them because I needed two of them and they come in a bag of 20!

Problem solved. make a simple panel to cover the opening, drill holes to match the holes in the case, insert 2 of these.

It lost its battery door somewhere on the way. I will send a silver dollar to anyone who can supply me with one. I suspect all the large plastic box underarm Tesoro's used the same box and battery door.

Thanks, it looks so silly with scotch tape over the opening.

We are off to Norway in July for two months. I will have a couple of (I hope) well chosen detectors for the usual run of field, meadow, park stuff.

One thing though. there are things older and deeper than my VLF's will find. I detected in Norway a lot in the 90's and found nice stuff, but I didn't have anything which could go to depth on any metal targets which existed.

One interesting thing (sadly) in Norway's history is that th eBlack death hit Norway very hard. about 65% of the population died. Unlike more settled village and town settlement patterns in Europe which helps recovery, the Norwegian population was largely rural on individual farm sites.

the place names all over Norway are sprinkled with places, now often in the forest - Called ødegård - old abandoned farm.

Having a detector which could double VLF depth in all metal could be a really interesting exploratory tool. Mind you, any objects dating from the mid 1600's are National treasure, but I am not looking to supplement my vacation budget and I would fully comply with the rules about that.

I am thinking a ML PI with a more modern battery arrangement which I could manage to legally get on the plane. I don't care about small gold - there isn't any - Would an SD be fine, or is there a reason to go to the GP or GPX range. light is better and old lead acid or other bulky batteries are not good for air transport or my old bones.

Your thoughts.

Tom, I have a modified IDX Pro and the correct Bigfoot. I plan to sell it, are you interested?

mine is the original. I have no idea if there would be any difference between the various ones.

I claim to be shocked and surprised.

One big caveat. I haven't tried it in the dirt.

One other thing, I live in a tightly built development, there are dozens of wifi routers around, they make most coils nuts with noise.

The Bigfoot is deaf to all that, quiet as a mouse

I just got a perfect closet queen MXT. Absolutely like new. On a whim, I decided to try it with my Bigfoot for DFX/MXT.

air test only, coil lying on a table.

MXT in relic mode with full boost....shock.

ID on a dime at 7"+, nicely audible threshold break at 9"+.

Whatwhatwhat???

OK, so I try the 14" elliptical DD. 2 to 3 inches less...

So I power up my OK DFX in its deepest mode - prospecting...with the same Bigfoot.

a bit less than the 14" ...

I have searched the forums a bit for experience with the Bigfoot and the MXT. I have found no such results.

Need to get in the dirt with it.

Skål og godt nyttår, James. 

Greetings from Arizona. We will be in Norway in July and August, (same procedure as last year) where are you located?

I have made an offer on the Lobo Super Trac

thanks for everybody's interest...and yes...I am showing off.

Some may have noticed my long absence from the forums. Thankfully it was not that I was deceased or even seriously ill.

Some things interfered with my enjoyment of the whole scene a few years ago and now, I am over it.

Just bought the 1236X2, a Perfect early MXT, and planning my battery to attack Norway for two months this summer...details of the machines to be revealed later!

excellent condition, coils various condition as in pics.

here's the "in between one"

Cal,

My Pantera is now in the Classifieds

my uncle Harold, long deceased was a sonar man on a USN escort vessel in the North Atlantic in 1943-1944. The accomplishment of their mission to protect convoys and their own survival depended on the audio intelligence that the ears and brains of Harold and his shipmates could derive from analogue audio signals.

Audio is a rich and sometimes undervalued source of intelligence, just ask a whale!

I am busy archiving lots of his posts other places, no website is forever...

here is a concrete example of what I am talking about...Keith at his finest...

"What's funny on analog audio only machine especially the Tejon once you get hours on them and know them like the back of you hand at least to the operator in control of it .A coin of high conductance has a different ring to it vs a nickle ..they both sound tight and round but you know its higher the way the signal snaps.The edges f the signal the rise and fall of the target is very telling on conductance of a target on a single tone unit.Nickles hit's later and stops shorter in the instance of peak hit like a rise and and fall but round Vs a coin that hits sooner and ends later with a sharp rise and fall though round and tight too. Low conductors like to start off sort of laggy before the sharp peak where as high conductors like to snap to peak almost instantly..You may not know it or even sense it at first it takes awhile and alot of holes dug to paint a picture that one day your 6th sense takes over when your swinging and you can start to sense TIMING of hits that are round.I'm talking nano seconds delay but after awhile you get a feel for it.If you try to notice it you may never in a learning environ. but after awhile even years of analog no Visual ID on same unit use day in day out your doing it and dont know your doing it.Even foil etc can become wavy and weird sounding..NON ROUND.Subtle waves in report.

Analog audio has tiny minute audio traces that a digital machine can not convey.Digital is getting better but there's still a place for audio aficionado hunting".

A concert of information vs a number...lovely!

My esteemed pal Keith Southern is a virtuoso of metal detector audio. Not only is he a highly accomplished and respected detectorist and hunter, but he deeply understands and appreciates the audio languages that they speak. I once was so inspired by his insight that I began to link it up with some very limited knowledge of information theory, dim remnants of the "Observe, Orient, Decide, Act" air combat theory as defined by John Boyd which us dumbass USAF Pilot Trainees struggled to grasp, and a couple of glasses of wine and came up with this...

The purpose of a metal detectors user interface is two-fold. 

The first purpose is to allow user control of operating parameters. These include all the well known things like sensitivity, ground balance, discrimination, audio characteristics and visual display characteristics. 

The second purpose is to inform the user of what the detector is extracting from the target signal. The extremely faint electric currents induced in the target are processed in the detector and presented to the user by audio or visual means. This target feedback information - through the operator’s ears and eyes has one purpose - to cause a “Change of State” of the operator. 

There is no observation unless there is a change in state of the observer.  The energy to change that state comes from the phenomenon being observed.  The energy supplied by the phenomenon to change the state of the observer is no longer part of the phenomenon that was being observed.  

Keith reported that he had good results in specific circumstances with this detector due to its rich audio feedback. The energy given off by in ground targets was analyzed by the detector and presented as a complex audio signal through the headphones. The result was a “change of state” of the operator - Keith. This caused him to either dig or not dig various targets. He was pleased with the results based on his decades of experience hunting similar targets under similar circumstances. 

There is nothing to suggest that the largely analog single frequency circuitry resulted in inferior performance to more “advanced” machines utilizing digital signal processing instead of analog hardware signal processing. The absence of any visual user information doesn’t really have any relevance as long as the audio information is “conclusive” - that it caused the correct “change of state” of the operator. In the case of a metal detector it would mean desired targets dug, undesirable targets ID as unlikely to be worth digging. 

To better understand where Keith is coming from in his love of a complex audio interface have a look at his post from December 2016 titled “The Future of detector design will be Sonically aimed”
