I tested a number of PI machines when I was doing that for Kellyco.  Two issues I had and never got over with the PI:

1. No useable discrimination… no matter what the advertisements claim.

2. I got real tired real quick of digging 20 inch holes for a Bobbi pin!!😡

Thanks for good post. Yes.  A real drag digging trash.  I guess the point is that with my D2 testing on 2 gold rings and 1 silver ring down 10 inches  (all well spaced apart as a test in separate holes) on a beach with heavy black sands  using Beach Sens and Beach modes (Relativity and Sensitivity tweaked in the many was suggested here) the response was high chirp and then iron "grunt" on all three rings.  Previously another poster here mentioned the same thing so he notched out the high tone and the grunt tone.  Replies from others to this poster were both yay and nay.  So, what I learn from my test is that if I do not dig everything I would miss gold and silver rings.  So ... that was the reason for my post.  If you have to dig everything anyway because discrim on the D2 fails at 10 inches in beach with good degree of black sand then why not a PI?....  I am still new to the D2 and I am certainly not denying perhaps more experience might sort out the discrim on the D2 .  I am going to try this same test again perhaps using a different factory setting such as General.  Good hunting! 

First.. thanks for posting "strick".  I sold my TDI pro.  Hindsight is 20/20.  Good suggestion though.  Good hunting out there.   Cheers...

I have a D2.  I detect black sand beaches British Columbia ... similar to Washington coast I would think.  Beach mode Sens 92, Reactivity 2.  For a test I buried 2 gold rings 10 inches down and one silver, well spaced out.  On the ground gold IDs at 62, silver at 90.  Buried 10 inches down wet sand the D2 gives a high pitched response plus iron grunt for all three..  In other words dig everything it seems.  I tried out all the factory settings and Beach was "quietest" .  So my question is:  Why not just use a PI (if I am digging everything) as I understand this tech works well in black sands but goes off on everything.   I do point out that I only hunt beaches.  So would a PI be a best bet for me as opposed to the D2.  Thank you

Dig about 80% of that overburden off for as much of the length of those washes as you can manage first and then maybe you'll have a shot at finding something with a detector.

1m of overburden is quite the unrealistic depth to think of finding nuggets beneath, especially when you consider extra depth that crevices and unconformities in the bedrock present.

Digging beforehand will be 100% necessary with that kind of depth unless you discount the bottom of the wash and hunt the banks. Then get what you can afford, learn how to operate it, and if there's gold present, the detector will see it.

Gold ouck!

I have been thinking of that idea.  Finding the most logically (gravity) wash and removing overburden.  I do have an Anfibio Multi and have been surprised at the depth but perhaps this "Minelab GPX 5000 machine with Coiltek 22" would be the way to go.  Any other recommends appreciated.

I would imagine an OKM eXp 6000 should work?  But if a 7000 is too expensive then the OKM is way too much. On the other hand, 20 ounces of gold would pay it off. 
I would defer to others with more experience, as I have never actually used an OKM but their claims on the website and the few reviews do seem impressive. 
Another option is to give me the exact coordinates and I will report back on if there is any gold. 😁

Yikes!!!   And still there are 30,000 reviews of buyers

Sevatras:  Thanks for the post ... got a good laugh there.  Appreciate the replies ...what a knowledge base here!!  I will report back on this project as we move forward.

.....good luck out there

Thanks Neb.  That is good advice.  I have been using an Anfibio Multi over the years with good success but not for something this deep.  The difficulty with your suggestion is there is simply too many wash trap sites to make that practical.   If nothing can detect that deep even for large target then we will have to find some aspect of your advice that may work for us.  Thanks again.

Fall is arriving on Vancouver Island Canada with cooler weather and some rain.  The forests are increasingly resistant to fire and safe to enter.  Our mining claim is at the 4000-5000 foot level on the side of a heavily forested mountain.   After testing several washes with a long prob we were finding depth to be in the vicinity of 1 m / 3 feet.  I do have an Anfibio Multi which is not suited.  Looking for advice on buying a detector for this depth.  The washes we surmise hold decent cache of placer and we also suspect a small vein is nearby.  So, the washes to be investigated would contain decent sized targets not pickers or flour gold.   I have heard "Minelab GPX 5000 machine with Coiltek 22" DD Goldstalker coil" and "JW Pulse 8x" would be suitable.  I would appreciate your comments.  I also am aware of the Minelab 7000.  Although the price is high and we do not seek overkill or other uses except for this project the 7000 would have to be considered.  Good luck out there and thanks in advance for posting if you do.  

I just read "phrunt's" post.:  December 23, 2018 in Minelab Equinox Fan Club

...about black sands.  I did post on another forum about this and I hope I am not violating an etiquette but the topic is recent here and comments helpful.

I am newly using the Anfibio Multi but beginning to realize perhaps this detector was not the best choice and perhaps a PI better.  I liveaboard my boat on Vancouver Island pretty much year round voyaging the entire coast Vancouver to Alaska including islands. Today, first time using on the beach the AM could not settle down over regular looking sand interspersed with layers of black sand. Since most all of my detecting will be coastal coves, harbours and their beaches most all with black sands I am wondering what detector would be more suited. 

This was said by poster "phrunt" which was interesting with regard to making the "right" choice for my hunting grounds.

"I find the fine coatings of black sand to be the most difficult no matter if I use a multi frequency or a PI."

Thank you

Not getting such great reviews in Oz.

This youtube Oz review not so good either:  https://www.prospectingaustralia.com.au/forum/viewtopic.php?id=20924&p=9

.... Out again tomorrow on a copper claim Vancouver Island reportedly gold in the copper deposits.

Thanks.....  I had a multi unit plug into main plug which I removed and went direct charger to wall outlet... works fine.  

Testing phase of this new machine.  Tomorrow I will be going out to a copper claim on Vancouver Island.   Geology reports that some of the rock may contain gold.  I have not charged the battery since purchase.  Today I plugged the lithium ion battery into the wall charger in prep for tomorrow but did not see any light.  When I first un-boxed the unit I plugged the battery in and a red light came on.   The next day the light was green (fully charged).   This time no light.  Does this mean the battery is still at a high enough charge?  Does this battery require a full discharge before re-charge or should it be plugged in after every use even if just a few hours?   Many thanks for this...seems like not a very important question but I did not find any reference on ML site "search" function.   As far as the unit itself for my wee spot of the globe ... too early to tell.   It did find a few old coins in my lady's flower bed first go round.   Looking forward to testing it out tomorrow on this very large copper claim in the Port Alberni area.

Thank you Chuck.    My concern was related to the "construction" of the detector which looks flimsy particularly the battery "lid" compartment.  The only other detector I have used for the past 5 yrs or so has been a TDI Pro by Whites which is rugged to a fault in comparison.   I believe the guts of the 1000 are solid ML tech.

Just received my GM 1000:

(As posted on another forum)

First outing today for 2 hrs in a trashy garden. Picked up two 50 yr old Canadian coins (quarter and a penny) in deep all metal mode showing non ferrous.... ok so far. On the other hand this detector has a flimsy, cheap feel to it despite not expecting heavy duty at that price. The "lid" for the battery compartment I believe would embarrass even "made in China". However, time will tell. My previous detector was a Whites TDI... very tank like. Had I not had such a good offer ..would have kept it. My bro has a Fisher Gold Bug 2 and the GB pro. I am sensing a bit of regret I did not go the same way.
