Some YouTube videos already.


Will it be the next must have detectector.


I predict its performance will be exactly the same as any other. However time will tell.

Talk on other forums seems to suggest its Multi-Frequency mode is similar to Whites DFX operation. That is to say, not the BBS alternating bursts of two frequencies, but continuous transmission of both frequencies, in a square-wave drive. Whites used 3kHz & 15kHz, I guess the lower frequency of the Equinox will be 5kHz, as that is its lowest single-freq operation, and the higher freq possibly 15kHz or 25kHz, though neither machine offer 25kHz as a single frequency. This continuous transmission may allow the higher response speed that the Equinox appears to have.

I can't help wondering if the 'IQ' part of Multi-IQ refers to the quadrature vector components I and Q, which are demodulated. (rather than suggesting the machine is smart, ie. 'Intelligence Quotient')

. Twin coil processors DPT (dual processor technology) — one to process the ground signal only and auto GB the entire time to negate minerals — the other working in tandem with multiple processors in the tiny control box to focus on the target signal



Your not going to be very happy if this out preforms the CTX if you just bought one.

If it works as proposed and priced, it will be real competition for all detector makers.

This might be the patent?

Minelab infringing MY COPYRIGHT? Not that I care anymore LOL.

Since there release of a new machine I've noticed a huge increase in XP Deus and other units for sale by well know detectorist.

if the new minelab works like the whites multi frequency machines then i wonder how minelab got around any copyrights...i have read that both whites and fisher are bringing out a new machine and i wonder if minelab have made their new machine to compete at a much lower price.

While my earlier post speculated it was dual-frequency like a DFX, I wondered if it could use DDS/Direct-digital synthesis to drive the coil with multiple sine-waves, eg. 5kHz and 15kHz. There wouldn't be any problems getting appropriate drive levels of the two frequencies. The weak 3rd harmonic in the 5/15kHz Fisher CZ-series is apparently one of it's troublesome features, and the DFX square-wave drive signal is one way of increasing the 3rd harmonic level. But sine-waves bypass these limitations entirely.

Has anyone investigated the workings of the lots-of-frequencies Rutus Alter ? That may use DDS.

Guess we will gave to wait for part 2 this says very little

Do I read this right.

Part of the ground response is eliminated by measuring the Tx current giving better target ID

Is this true ?

[dbanner]

Is there any way to actually see just what these multi freq. detectors are putting out(scope) or are we to read patent jargon and surmise endlessly?

Hi alll,

this is an old technology. I had it already realised approx. 5 years ago with my netbook pc and sound card interface.
I/Q demodulation can be done via digital (software) Lockin amplifier or just a plain FFT.

This sounds familiar .... don't some existing machines do this? I'm thinking of some of the older Fisher machines (like the 1266 etc) that had a small 'audio' transformer in the circuit between the TX stage and the demodulators.

This is what the X-Terra's do, and it seems like the Equinox is of similar design to them (high bit-count ADC straight into a microprocessor). Presumably the 'new' tech is how they then go about processing two-or-more frequencies. I assume there's several ways you can combine 2, 3, frequencies. The Whites V3 has several options, there's likely to be more in the Equinox.

Of course, it's quite simple, and when they become available to the public, no doubt someone will do this.
