Weird , my gnd level ( GND LVL ) shows nothing  ...  ?!?

Did you pump coil more times on that soil?

What is your ground mineralization level in your area ? I mean the G.ID displayed on the D2 RC main detection screen ? Mine is 79 ,  Thanks ...

Similar phase, between 74 and 79. But with a high strength, with bars of the graphic full..

Have been using D1 since 8 years now and with D2 principal options are familiar. But in my opinion it’s a very different machine starting from the fact that it’s much more stable than D1...no chattering and much more depth for example. Leaving out the fact that there is no escape if it starts to rain. And VDI is much more reliable even in depth and on mineralized soils as well..

Thanks for your nice report. In my area, central Italy, on high mineralized hematite best program for relic hunting, I’m talking about little targets like the 2g coin not bronze but mixture one,  is number 2 which is better than 1...excluding Goldfield.

Hunting around obvious iron targets is very different than silent masking where a machine might not be capable of reporting an iron target and instead just masks out the targets around and below.

Find a piece of rusty sheet metal, doesn't have to be big and you will see a good example of what happens.

Was forgetting to say that V6 was with discrimination on 4, nails were totally cut out..

This was the test. Nails driven into the wall of the 6” hole were 5, from 2 inches to 4 inches. With 1 nail next to the coin in the bottom. Unfortunately video is in Italian language..

Same test but with 10 euro cent coin in the bottom of a 6” hole with 4 big rusty nails driven into the wall of the hole. Lost picture of the hole. It’s in italian language.

Here using D1. Italian language, sorry. Anyway here with a 50 euro cent coin, reactivity 5, silencer -1 and full tones. 4 big rusty nails. Same test as V6 above.

I’m sorry for these short videos which are in Italian but I had to do a V6 review...6 years have passed. I was younger!

Sorry if I resurrected this thread, it’s absolutely interesting because   exhaustively illustrates an important topic such as iron masking.

Years ago I organized an extreme iron masking situation with 20 euro cent coin in the bottom of a 6” hole. Very hot soil near a seaside town in south Italy. Hole with 6 big and rusty nails: 5 driven into the wall of the hole and one next to the coin, in the bottom. I was testing one of the best machines I’ve ever used: Blisstool V6, in this case with a 7x9” SEF, little great coil. Machine managed to detect the coin, however with a slow and carefull sweep.

I'm real worried about the chatter. I finally had to sell both of D1's because they just plane sucked for too much chatter. I tried everything and never could settle it down no matter where I was detecting. Watching all these D2 videos it does seem much better so I HOPE so or I'll be selling it pretty quickly. Is it much quieter than the D1 ya'll???

Yes, is much quieter. I’m sorry about that because I like D1 chatter. Anyway I agree with abenson, D2 seems to be much deeper. I’d like to do an extreme depth test on mild soil..

Well done abenson, great finds!

Sensitive is my favourite program. I have my own program which is based on prog.2 but with pitch tone and variable reactivity depending on the iron in the field. Sensitive prog is good on mineralized soils as well. Prog 3, Sensi FT, would be my favourite because of full tones but full tones on mineralized soils are not as performing as prog 2. Crotal bell is really nice!

I usually pinpoint swinging and using the back of the coil and then turning 90 degrees. Learned with a Blisstool which doesn’t have a pinpoint mode. 11” coil is quite accurate but a 9” is obviously more precise. Anyway in my opinion 11” is the right size for relic hunting in open field..

Nice reading with a particularly beautiful second photo. Thanks

May I ask is the coil 9" or 11" ? Thanks

It’s the 11” one..

Just come back from a mineralized field. Tested Focus 1 prog on a 6” low conductor target covered with scotch tape. Scotch to make target larger therefore to find it more easily. Soil is really high mineralized and also pinpointer screams. Thanks for watching and bye for now.

With D2 there are no differences between iron volume 0 and 5. Anyway  I have to say that on mineralized soil is much better than D1. Bye guys!

Back where I park the car for the same test but with a smaller coin, 10 euro cent coin. Prog.2 with Iron volume 0, disc 6.8, reactivity 2.5 and 4. Silencer 0 as well. It’s the smaller sister of the 20 and 50 euro cent coins. It’s 19,75mm in diameter and 1,93mm thick.

I noticed about this behavior on Deus 1. I’ll try with D2. Next time I’ll go out with detector I have to test also a program and see how it reacts to mineralized soils. Let’s see. Bye for now

Hi all. Program 2 with disc by default (6.8), Iron Volume 0 to cut totally out nails: I think that with nails cut out this test is more difficult because of iron masking obstacle. Coin is 20 euro cent coin, similar to 1 nickel talking about dimensions. It’s a 89% copper coin.

Thank you very very much for this qualified and exhaustive answer. I’ve searched some verbs in the web because my english is little and I think american language is even more complex. Anyway I understood everything. I’d like to make a quick video about iron volume but I have to come back on the red dirt and it’s not just around the corner. Thank you again for you answer, I appreciated it very much.

Years ago I had a test garden on low mineralized soil with 3 coins buried in 12, 14 and 20 inches hole. That coins, 50 euro cent coins, have been in the bottom of that holes for years. But unfortunately, land owner plowed the part of the field where I had arranged the little test garden. Now have to make another one..

If you are talking a mixed ferrous signal or target, if depth is affecting the ferrous component, I.e., driving a signal from mixed to full ferrous as the target is moved further from the coil, then with iron volume off (0) you of course are no longer going to hear the target at some point whereas you will continue to hear the target if you have iron volume on as it transitions to a full ferrous signal at depth.  That would give the false perception that iron volume affects depth.  It should have no effect if your target remains fully ferrous or fully non-ferrous during the depth excursion regardless of the iron volume setting.

I’m predominantly talking about these iron volume effects on mineralized grounds. For example, a coin with similar dimensions to a neckle put in the bottom of a 8” hole for a depth test: no signal with iron volume 0, mixed signal with iron volume 5..not a totally ferrous signal but a mixed one. And  with iron volume set to 0, there were no signals. I know this can be seen like a weird behavior and it’s weird for me too. I’ll try to make a video about this. Thank you for your kindness and see you soon.

In italian we talk about “drift towards ferrous”, specially on mineralized grounds. And with iron volume 5 vs 0, it seems that this “obstacle” can be overcome..

You might be confusing another setting, perhaps?  I haven’t experienced any depth loss resulting from where I set iron volume on D1.  It should have zero impact on depth.

I agree when you say it should have no impact on depth. With D1 there was some differences between iron volume set on 0 and set on 5. I’ll try with D2 as well. Thanks for your answer.

Iron volume is not a filter at all.  Iron volume merely let's you hear discriminated iron tones with a coarse volume adjustment.  Discrimination is the filter in this case.

Thanks for your answer! But why on D1, there is a depth lose between Iron Volume 0 instead set to 5? Thanks in advance.

I’m not an engineer but only a simple md passionate. I like this thread because is really interesting. My question is: is iron volume a filter when is set to 0, and so when iron is cut out? Because in my opinion it becomes a filter only when is set to 0, discriminating iron.  Let me know please, because it’s not my intent to write inaccuracies. Thanks in advance.

Thanks for your interesting video Shopkins. I’d like to deepen one feature: you talk about iron volume set to 0 because also iron volume is a filter..I agree with you when you say that it is a filter, but in my opinion it becomes a filter when is set to 0, because in that way you cut out iron. If you set it to maximum level, 5, cpu doesn’t have to filter anything. The first Deus, mostly on mineralized grounds, is deeper with iron volume set to 5, compared to 0.  I’m curious to test this feature on D2..

Just tested Deus 2 on a little and thin piece of foil..I’ve used as usual my hematite stone which is extremely mineralized. So, I’ve a new program for mineralized soils: its name is Focus 1. It’s based on prog. 2 but with Pitch, disc 6, iron volume 4, audio response 6, recovery 3 and ground stabilizer 1. Ground Stabilizer is very important to reach depth...on mineralized soils for sure. And here is a little video. Sorry for the very low quality..
