The Ideal, The Perfect, The One!

Hello,

may I, as a newbie on this forum... ? Do you allow "futurology" ?

My dream machine would be

    * basically analog - I still think that in the open air the human being is more receptive to analog signals ! I do not need a screen, my eyes look at the ground and help me not to fall down.

    * made of 1st class components, famous and clearly identified, not SMC (this would allow easy repairing) not covered by any kind of paint (I am a Minelab user...); may be I am na?ve, but I do not think that a perfectly designed machine would necessarily be copied. I compare MD with some modern High end Hifi equipment that could have been designed in the 70s.

    * modular, with digital extensions, to be issued in the next years and decades

          - 1 - (2015) DSP with Markov model (it works in speech regnognition, so why not...) + AI, soil / target database and learning capabilities - a global database would centralize the international information

          - 2 - "pulltab 2020 (year of availability) module" : I would like the MD to tell me "pulltab" when it IS a pulltab (this would be a dream machine indeed and I do not care about the technology used, be it radar, thermo, shape recognition, Tommyknokers technology...)

          - 3 - (2025) multipurpose analysis giving some characteristics of the target: crystal or not, pure or not, alloy, ore... (OK I am dreaming)

    * relying on standardized coils (or include this universal coil enabler developped by Whites and Coiltec in the early 30s (2030s) )

    * (2040) floating (I mean, the coil, thanks to an air flow or (2100) an antigravity module) at the optimal distance to the ground, calculated in real time by the MD; thanks to BT, coil would no more be on the shaft.


I do not need more depth (I do not hunt on sand beaches) but a better discrimination and sensitivity to small targets. What I realize is that I have to improve the MD user more than the MD itself !


regards,

Joe Chip

*how about my dream detector it would be like sunglasses that would let you see deep into the ground with out any heave box es or wires like, and would work like an ex ray machine but are lite sunglasses?

the only draw back would be the feeling like your up high looking down lol we would fall from vertigo on the ground

thanks GD, and thank you for your very useful explanations about the reaction of metal items to the MD field - very synthetic and precise. Do you know, do you have any reference concerning alloys, ores and other minerals ? I am interested in minerals and plan to use my detectors in order to find interesting crystals (and other nice stones - not many gold nuggets in France unfortunately  ) but the only information I have is binary and about the mineral conductivity and magnetism : yes/no.
Thanks, regards, Joe.

A television screen on top of the searchcoil...with audio off upon valid target signal of course.

	I was thinking lately about gold resonance (I did a search and found this post). GD, if you build an oscillator circuit that transmits pulses of signals varying in speed from 1.7ghz to 3 ghz and set up your RX to read the reflection of those pulses you should be able to read the dip (as mentioned earlier in this post). The particular dip could be interpreted and actually reveal the purity of the gold. These transmissions would have to be "directional" and received in the same way in order for the direction of the target to be displayed. Distance to the target can be easily calculated and displayed as well. How to distribute the range of pulses in their specific directions is the part that's hounding me  . Could these frequencies (which are already in the microwave range) be piggy-backed on perhaps infrared? One last question.... If I were to build this device will I cook my own foot? Thanks and HH yall, Ken

Wo! I thought he said megaHertz, was it really GIGA???

I have had some thoughts and will pass them on: a swept frequency, but the receiver has to be swept, in  unison, then do a circuit that screams, if the return/reflected energy drops below a settable level.

I will have to go back and re-read that exchange!

Actually cooking takes place near the water-hole frequency, which is much higher, and many, many more watts than you could carry around. The microwave ovens are a frequency sensitive cavity, so food disturbs the cavity and absorbs some of the klystron energy, which heats the water, in the food. This frequency is somewhere between 20 and 30  gigaHertz

That is a very simplified explanation. And do NOT belive the one about the lady drying her mutt in the microwave.... folktales.

I checked and he did say megaHertz, so no chancy of cooking feet.
