Single and Multi-Frequency Machines

[CoilFisher]

I have been reading up on this. I would think a multi-frequency machine would give a better discrimination and more accurate ID because you are processing more than one signal on the same target.
Any takers?

what a multi-frequency detector does for me is it give me so so much more information to process and more ways to help determine if you should dig or not. In the beginning its information overload but it takes 2-4 weeks to get it figured out. I couldn't go back to a single frequency detector even if I had to!

Example: Here is how the DFX works. It sends out 16 frequencies from 3KHz to 92KHz which are processed using two methods. You select which you use.
---Best data method-analizes data from the most reliable frequency-for general use, parks etc.
---Correlate method- compares the two best frequencies and displays target info only if they agree. This is used for homestead type searches and eliminates targets like nails. Frank

I know for me doing nothing but saltwater beach hunting I have tried numerous single frequency machines and could not get any of them to stay stable in the wet saltwater sand. Dual or Multi frequency was my only option....

The DFX only has two freq, 3 kHz and 15 kHz and you can use both or one or the other. It can only send out two frequencies at once.

I have a Garrett AT Pro. It is a single frequency detector, but even in very dry, hard & somewhat mineralized soil, it gave me a correct ID on a dime down 7". Even some who use very expensive multi-frequency units like Minelabs say the visual ID is no good beyond 7", so I don't know if there is really a great gain. The expensive Minelabs will beep deeper, but ID may not be perfect. Best wishes, George (MN)

The Minelabs use multiple frequencies and processes them internally and gives you an Iron and a conductivity reading.
The White's V3i & VX3 use 3 frequencies and show you the response for each frequency. Different targets give a different response at each frequency. You then can decide whether or not to dig based on more information.
As you can tell, I own a V3i which I chose over the Minelab E-Trac. If you like to tweak the hell out of a MD to get the most depth, go for the V3i. If you want to tweak a little, get the VX3. A biggie for me in the decision was service. White's has come through every time, no questions. If you want to know about Minelab, just go through the Minelab threads in this forum.
Well, that's my $.05.

I have a DFX which is a dual frequency. I have not noticed any difference in the finding depths of targets using 1 or 2 frequencies but, using 1 or 2 frequencies can make a huge difference in stability when dealing with outside electrical interferences. And as mentioned earlier multiple frequencies are needed on salt water beaches.

white's, are the best....

I have been using Minelabs for over 5 years, love them, no problems...... Had a Beach Hunter ID, the thing constantly leaked and whites kept telling me it was becasue I wasnt closing it properly...BS.....
