? Re: DFX Technology

[heavymetal]

How old is the DFX technology? I remember reading that a user got his 6 years ago. Is the DFX technology old already?

 

[Dave Z]

About 5 years ago.Would make it late 90's technology.Probably about 7-8 years old.

 

[Ralph Bryant]

.....is based on Minelab patented processes which were licensed to White's, and used on Minelab units prior to the DFX. The original intent was for the DFX (or a similar White's release) to actually be a 3 frequency machine, but due to contractural time constraints it was scaled back to 2 primary frequencies operating with 16 harmonics from the basic 3 and 15 kHz in a very similar way that BBS and FBS works on the higher end Minelab machines.

There is nothing "outdated" or "obsolete" about the technology, though it is several years old, and still used in some of the better performing top-end machines on the market. Some people like multi-frequency machines (basicly time-domain based modified pulse induction) while others prefer the simpler single frequency machines. Where multi-frequency really shines is in handling bad ground mineralization consisting of both conductive salts and ferrous-based mineralization at the same time, such as black sand areas on saltwater beaches where single frequency machines tend to have more difficulty.

It's both a dual and a single freq.detector.Want to hunt the ocean,use both freqs.,it's unbeatable.Tough ground,same thing.Want to cherry pick silver,use 3kz.Want to Relic hunt or look for gold,use the 15kz.Hunt in heavy trash,put a small coil on it,turn up the recovery speed and drop the filters.I can go to any site anywhere's and set it up to any condition I come across.I've owned other detectors that just flat out would not work on certain sites,Saltwater Beaches,Places loaded with Hot Rocks,Places with too much iron,etc.If there's a site that the DFX can't handle,I haven't come across it yet.Dave

I always thought it would be neat to add a feature to the DFX that would allow you to link straight to a PC to add or change programs. This way you could have a one or two page program with numeric scroll or drop-down boxes to change each setting as desired instead of scrolling through all of the settings on the machine itself. Also thought it would be something unusual to be able to build programs on an SD chip card and then have a slot on the detector to enter that single program into the machine. That would allow for a wide range of testing, changing, and saving programs to individual cards to build a program library of sorts.

Anyway, just some thoughts......

It was based on a early Minelab 3 frequency design of the mid 80

Disc have gotten so small I'm surprised some Maker has not come up with the idea you mentioned Ralph.

 

[Richard@BackwoodsDetectors]

ham radio operator, I owned a Ten-Tec radio that came out with software upgrades on a regular basis..... How about an upgradable detector that would let you to go to the company website and download new programs or fixes..... Ten-Tec was very innovative with this and bugs were fixed with the addition of new capabilities being able to be written in.....Just thinking out loud.... Tnx RichardnTn

 

[OldeTymer]

That was the original intent when the Eagle came out, but that changed after a couple of upgrades. If they continued to do that sort of thing, why nobody would be buying all these new units, and then where would the manufacturers be?

[Ralph Bryant]

If such a machine were ever marketed, the manufacturers might have to revert to selling software instead of hardware, something like the computer industry. But no matter how good they make one, there will always....-ALWAYS-....be room for improvement.

Couldn't agree with you more. That's what makes us keep coming back. I like it, I love it, I want some more of it.

hi, first post here and new DFX owner. trying to get up to speed.

has there been any software revisions yet? how reliable have DFX's electronics been?

 

[Monte]

I have used a number of DFX's and all of them would turn on and off without a problem.

I have owned 3 DFX's and they also could be turned on and turned off.

I was looking for a silver-shooter and was hoping a DFX would turn ME on, but after owning three of them and doing better with an MXT and XL Pro and other brands for silver, I found the DFX was capable of turning me 'Off'.

 

[Dave Z]

I only have 1 DFX.Had one of the first ones that came out>you jsut need to use it and program it properly.The factory presests aren't very good.That's why a lot of the buy and try guys don't do well with it.It takes a little time to learn.It has NO problem finding silver.I've found dimes at the 6-8" range while using the little 3x6"coil.As you can see by the stories below.If you learn it,you will love it.Check out the DFX fourm and ask questions from the guys who actually own and use one.Check the link out.7th story down is what I took out of 1 cellar hole with a DFX.6th one down shows you how well it finds silver.You just need to know how to program the machine and you'll do fine.Dave
