What's wrong with the DFX's ground tracking methodology?
I would assume that the Vision will incorporate DFX ground tracking algorithms.
The display quality does appear to be first rate. Just hope it passes the 'sun glow' test !!!!!!!
Well guys and gals, 2009 is proving to be an exciting one for choice of 'weaponry'.
E-Trac.....Vision.......and more to come.....Oooooo. Guess which one is next ?????
My question to you all, is this:-
What are your expectations / desires of the White's Vision?
(1) Greater depth ?
and / or
(2) Improved analysis / discrimination ?
~~ ~ ~ ~ ~ ~ ~ ~ ~
Some of my personal preferences would be:-
Choice of audio customisation. i.e. Assigning class of targets sought, their own distinctive audio signature. The Garrett 'bell-tone' always appealed to me.
Retention of DFX 'averaging' On-Off control. I use Average-OFF, together with a high visual gain level. That allows you to see several targets in the S'graph.
A reading of the ground's Mineralisation factor.
Minimal weight and a well, ergonomically balanced unit.

It's well known that in many locations the DFX will not work while the MXT will thanks to it's more aggressive ground tracking. Additionally, besides just that fact, if people want to use it with the higher frequency for gold detecting, the MXT ground tracking would be MUCH more beneficial for prospecting.
That's why people who want both coin and nugget shooting buy the MXT over DFX.
Still waiting for a chime in to settle it.

Is it as aggressive as the MXT / GMT, or based on it though? How does the ground tracking compare to those units? My understanding was the ground tracking wasn't just a simple "software" thing or else I'd have thought given the feedback it would have been incorporated onto the DFX long ago.
The tracking system in software is different than the MXT but still share some similarities, but they are still different systems. In my use I have found the tracking to be very adequate to keep up with the ground changes going from mineralized ground to moderate ground and to somewhat weak ground.

Thanks for the reply Bob.
I can appreciate the 'new' software aspect, to match new hardware platform etc., but are you saying that the underlying GB principles employed are different?
Does the Vision have 'Trac inhibit' , 'Tracking speed', etc., as with the DFX...?
Can you please tell us if any search-heads other than the stock coil, will be immediately available? Thinking particularly of a smaller elliptical.
What is the anticipated release date for the UK?
Has it already acquired its EU certification?
Best regards..................TheMarshall

Hi,
I've talked dozens of people out of buying a DFX and gettting an MXT myself, having used both units. My issue is not the ground tracking. My issue is that the MXT simply hits small gold better.
The reason for that is that the MXT applies more voltage to the coil than the DFX - the TX Gain. The TX Boost on the Vision combined with the higher 22.5 kHz frequency is likely to close the difference that exists between the DFX and MXT. The ground tracking speed is fully adjustable on the Vision. I'm quite hopeful the Vision will exceed the DFX for gold prospecting capabilty. Will it best the MXT? I suspect that will depend on the exact situation. I'll certainly be out hunting gold with it as soon as the snow melts.

Yes the ground balance system has to deal with three frequencies to balance the ground so it is different. More people will be able to voice their opinions if its better same or worse as time goes on but I think the ground balance system is improved but people will voice their opinion on this and many other features as time goes on.
There is a Trac inhibit that will not allow the tracking system to start ground tracking if a target is in the range that dirt fall into until it see this target more than a once or twice and then it will start tracking slowly to that change. If Trac Inhibit is off the ground tracking system will start immediately tracking to the change in the dirt region.These target could be iron, hot rocks, cold rocks or any other target that would in the dirt range.
The Trac Speed goes from 1 to 100 and this will be how fast the tracking occurs when AutoTrac is on.
Loctrac is the ability to turn the ground tacking off.
Ground offset is either to give the ground balance a positive or negative ground balance.
Ground balance can be obtain by pulling and holding the trigger and pushing enter and holding it down at the same time, and then pumping the loop up and down on the dirt.
As for EU certification we are currently working on that and hopefully it will not be to long.

Got all the right letters... Jeff Foster also did field testing on Vision, and I'm hoping he'll drop in with his comments. I don't have much time on the MXT or GMT, but I suspect tracking on Vision isn't as aggressive. But then again, I've not used Vision with Track Speed cranked up... I tend to run at 25, and max is 100.

Hi,
I am not disputing that. I am saying I've not actually run into a situation where that mattered. I do know it can actually hurt. What does matter is the DFX not having the ability to detect gold as well as an MXT. That applies no matter where you prospect. The difference in ground tracking would only apply in rare circumstances. And in those circumstances I would simply have to work slower with the DFX. More aggressive does not mean "deeper". More aggressive means "faster". When chasing gold I usually run the MXT in locked because that aggressive ground balance will aggressively tune out very faint gold signals either from very tiny bits of from very deep on edge of detection depth larger gold.
I've found several pounds of gold with the MXT so I'm pretty familiar with it. I did also have a DFX - until the Vision came along! I'm hopeful the Vision will also replace my MXT so I can have one detector instead of two. But won't know for sure until the snow melts.

I like the DFX's tracking myself. I hear the price you pay for aggressive tracking is a little more noise for the added depth. Not a bad trade off, but I like mine nice and smooooth.
I get very good depth with the DFX, even using the factory programs. I my first day I hit a buffalo nickle at 8" in our worked over park, and it even ID'd solid. Here in southwest Kansas we have fairly mild ground. I recover coins at 9-10" on a regular basis in the city park, but it still only gets me back to the 1930's and 40's. This park has been flooded every 30-40 years depositing 3-6" of mud on each flooding. The park is 125 years old and in the lower locations I've recovered coins back to the 1880's, but there are those areas with really deep coins, I know are there, just waiting for the right detector to pull them out. The Vision just might be that detector.

I remember someone talking about an area in CA (park) that is terrible. The DFX would not work, an Explorer would, as would an MXT. For the MXT, it was all about the ground tracking. I'd really have to go searching to see if I can find the name of it again, but it was one example where NOTHING he tried with the DFX worked.

"Jeff Foster, author or Digging Deeper with the DFX, the advantage the MXT has over the DFX is a very aggressive ground tracking system".
I don't believe I've ever said that "the advantage the MXT has over the DFX is a very aggressive ground tracking system" without also mentioning that the MXT Drives the coil at a higher voltage than the DFX, has a faster SAT (and Hyper-SAT) system than the DFX (which helps in enhancing audio contrast of small targets in noisy ground), and a very aggressive ground tracking system.
I recall reporting that an early Vision prototype did not have a max S.A.T. speed that would approach the MXT speed, and I believe that that was addressed. (But I don't believe the Vision includes the Hyper-SAT ability.)
