Multi-IQ Frequencies & Tones

Recommended Posts

When I called ML today and asked about Multi-IQ frequencies... Mums the word!  In their M-IQ description ML states the single frequencies are used... "and more".  Makes me ask how many more frequencies?  Has this been touched upon here and does anyone know how many frequencies and their range?  MLs only answer to that is M-IQ is a new technology.  So I speculate something similar in frequencies to BBS or FBS, because of the 50 response tones selection?  Might this mean M-IQ runs 50 frequencies?  Or might target tones be determined by some other factor?

Chris -- I am pretty sure the tones will have nothing to do with how many frequencies are being run...

50 tones = 50 ID segments from -9 to 40...so that you could assign one tone per each ID number, I am almost positive...

There are a lot of threads on this <Minelab Equinox Fan Club> sub-forum.  If you haven't looked through them I suggest at least a quick scan of each.  Tons of info posted by Steve.

Unfortuantely 'frequency' is often used without a qualifer and it can be confusing, for me particularly.  The reason I have trouble is because an Inductance Balance (IB for short, which includes all true VLF detectors and sometimes detectors labeled VLF which aren't operated in the 3 kHz to 30 kHz range) transmits radio frequency signals.  Even Pulse Induction (PI) detectors pulse at a regular rate which technically also qualifies as frequency.  But the real overlap in terms is audio frequency (sometimes called 'pitch') which is where the 50 tones on the Equinox comes in.

Here is a thread (one of several) which illustrates the five radio frequency transmissions of the Equinox:

I'm still wondering how many frequencies the Equinox runs on in Multi?  We know how many Frequencies BBS and FBS offer.  I must be mistaken thinking Excalibur tones correspond to frequency response?  Either way I'm wondering if the frequency range of the Equinox in Multi are 5, 10, 15, 20 and 40 combined, or a wider spectrum as implied by ML like perhaps 1-40/50+, the above possible chart range.  That could correlate to the 50 tones option?  Perhaps not, but I'm hoping the Equinox  works great in saltwater and we all know how well BBS / FBS does that.  I'm thinking the more Multi Equinox frequencies the better in salt???  I know, I know... I'll just have to wait!!!

Correct, you are mistaken.  The number of tones and the number of (radio) transmit frequencies have no relationship whatsoever.  (Correction:  I thought you were talking about the Minelab Equinox and my response was regarding that dectector.  All I know about the Minelab Excalibur is that it is highly regarded by many underwater detectorists.  I've never seen one in person, only a few on treasure hunting TV shows.)

From what I've read here, that is exactly it, nothing more and nothing less.  I don't know any more than what I've read here on this forum, and if others know more than what has been posted here they aren't talking.  As mentioned in my previous post, a lot has been written in this http://www.detectorprospector.com/forum/forum/53-minelab-equinox-fan-club/ sub-forum, and most of the informative posts are those done by Steve because he is one of very few worldwide who actually has a prototype and one of even fewer (among those) who has posted info on the performance.

GB is correct - tones and frequencies have no relation to each other.

Tones are for target id and are tied to target id numbers.

Everything known about the frequencies and how they work is collected here and I update it when new information is available. Only Minelab knows the real story and only Minelab should be believed on any of this.

I promise more details will be coming very soon. I the meantime, here are a couple articles I wrote to learn more about the subject:

      The users asked to ask the following question:
       Is the Equinox snapshot or open gate ? So where will the Equinox fall ? Your personal opinion.

      Hey Everyone,
      Just a quick question on warranty. How long is Minelab’s warranty on the Equinox 800?
      Thanks,

      Here are some Equinox Saltwater performance clues...   Almost as well as BBS/FBS.  My question now is define "almost".

      I would like to ask how the 8 speeds of the response of the 800-th model correspond to the 3-rd speeds of the response of the 600th model.

      Steve, having studied the shaft of Nox, it became very interesting to me how he had the weighting?
      The heavy coil at the bottom, the control unit with the battery is at the level of the hand, and in the counterweight on the armrest there is nothing at all.
      Logically, this combination should cause increased physical stress on the hand.
      Can you answer this question in detail?
      ps: judging by the angle of the handle on the shaft, I have a feeling that the Nox is designed to search under your feet.
      That is, holding the shaft almost vertically ...

      Is it possible for saltwater, or any water, or beach sand to get between the screen protector and the display when the Equinox is used submerged?
