Prospecting in Australia with the Whites MXT

		Quote:			Posted by Assembler
	Hello Have talked to a person who could 'Discriminate out iron / hot rocks'  away or off the ground / background rocks say 2 or more ft., using old 'analog type gold master' white metal detectors.  This by the way is what this one was referring to above thanks homefire.

Funny you should say that because I have one of the older Blue Box 5900Di Pro's that can do that, that is a very CoooooL feature.

	Hello Ridge Runner wrote:Yes it is a neat feature and can work with any frequency analog whites detector. Can at time make the difference of finding any type of 'Positive signal at all' with heavy iron / hot rocks in general by re-tuning a new 'Null point' on the iron in that test rock.  Flipping the trigger and pumping the coil on the MXT or DFX is also doing about the same to track out the iron. By having the rock sample up off the ground one can rotate or flip over the rock sample to 'scan' more of that rock.  This may be about the only way to use 'Discrimination on a older analog whites detector'?  Just trying to learn if the older 'Analog detector' can also be used with the MXT or DFX Whites detector out in the field. The older 4" Goldmaster probe is a neat coil.

Yep, My old 5900 is in showroom condition, you can see it if you click on my profile and scroll down the page at click on one of the photos, The owner bought it new and never used it and stored it in their loft still in it's box with the Original manual.

The only Whites Coil I am not at home with is the 4x6 because of the depth it looses and it is not as hot as the 5.3 ( 6" ) coil.

	Ridge Runner wrote: This may be more common then you think as this sounds about like the Whites DFX detector this one has as one small DD coil was still sealed in plastic.  The antic White detector and 4" coil was in like new shape as well.  Many people give up to soon with the metal detector they have and just put them in the closet.  Hope this does not happen with me as well as some people do not find any gold for years with there detectors.   Sill leaning here.

The MXT has to be about the most powerful machine out there when used properly when it is run like a TDI or a GPX and I had heard many stories about the older machines and how deep they could go and so I bought the 5900 and then I saw what they can do, In good ground no PI can beat them for depth, With the 950 coil it tests like machines with a 15" coil fitted, So If I put a 15" coil on it then any thing is possible,

I want a DFX / DFX 300 but it must be in top condition..

I don't know Ridge if you will like it. My experience was (Just borrowed one for a while but had a similar XLT) all I seemed to do was spend all day tweaking the software settings. The menu tree was not a fun place to look for all the variable settings. a lot of button presses required. I guess if you spent a lot of time on it you might find some settings to your liking for certain soils. Too bad they didn't have a computer interface where you could make settings in the computer software and upload to the DFX. All that said I know a guy that swears how great his was until he bought a Deos.....

Yes a lot of folks do that, which is one reason why I have held back from getting one or the V series, I can set the MXT from one hunt to the next and I'm good to go, The XLT and the DFX are great machines indeed but menu's wind me up because I just like to get out there and detect.

With the MXT / GMT think about finding targets at the depth it beeps and then it will be comparable to other high end machines, But as I said earlier if you use it like a TDI or a GPX then you will see the difference, The MXT has a Threshold Based Mixed Mode Audio signal response and when used correctly on some targets it can add up to 60% more depth depending on the targets type,

I have hit many coins in my soil in the 12 to 13 inch range just by using the Bleep / ID system and someone I know hit one very close to 14", But that is only one way to use the MXT,,,, Use it like a TDI or a GPX and that will change the depth dramatically and 95% of owners do not even know what it is for or how to use it.

With the Minelab GP / GPX series machines you listen for any slight rise in threshold and that is how they signal the operator that a deep target is present, If you Take Away the GPX's threshold then you will cut it's depth by Around 2 thirds in some cases which is close to 60%+ (66%)  Which makes the GPX a joke, But add a threshold and you end up with one of or the most powerful PI machine in the World, And this is what EVERYONE is Missing with the MXT,

Grab an MXT and using the 10" Coil and Air Test a Quarter and you will get between 11.5 to 12.5 inches The norm is 12", But use the Threshold Based Mixed Mode Audio and you will here that Coin at up to 60/70% more, This is what the 95% of users are missing. Forget Bleep and Dig Detecting train your Ears what to listen for. Some machines might air test a Quarter at 14 or 15 inches but after that the signal is Gone and you get nothing,

Like I said earlier run it like a GPX. It has this Audio system in every mode,, Everyone is craving more depth from their machines Or some new Magic machine, With the Coils I have and learning what to listen for, All I need is a better digging tool not a new machine. I must be the only person in the UK that goes Coin hunting with a Prospecting Pick.

When using this method think " Prospecting" Where just a Boot Scrape of the Ground is enough to Increase the Signal Quality and then sweep the Coil again and if you are unsure then Boot Scrape again and repeat if needed. And in some cases that is enough for you to get a good VDI Signal and if the signal does not increase then it is Ground Noise,

Hope this helps.
