    You are right about the TDI lineage - Alexandre based his development on the work of Eric Foster.

    The gold finding is not only big stuff deep, but tiny and low carat stuff.

    I heard there was a compare of the new Fisher aqua manta PI against a Aquastar II and I heard the results but wonder if anyone else has?

    Effort is Important, But knowing where, can make all the difference!

    I know no details, but the comparison with a specially Eric Foster tuned Aquastar was useful to Fisher and details of the design were tweaked as a result. LE JAG has posted that the revised current prototype is equal or superior to the Aquastar in all respects.

    a bit of history about the genesis of Manta
    I met Alexandre more than 10 years ago
    by a detection forum
    I already was using pulsepowers / rare at the time in France

    in 2012 we managed to buy an Aquastar
    one of the last product
    in 2013 Alexander produced three manta V3
    with Aquastar as reference base

    we were already better / more sensitive and less noise
    then there was the goldscan 5c / TDI reference

    continuing his research Alexander found new thing
    and markedly improved circuits

    then was born ,, the aquamanta 2016 celuis of the video
    a mixture of all his knowledge

    since he has further improved the circuit
    even smoother
    the sound of iron in reject mode is even more marked

    the separation of the voice of iron and the voice of gold is huge
    which makes it possible to detect an 18k or 22k ring or lower carat
    among several iron nails

    of course there are limits
    for example, we can not take the 24k
    in reject mode / it sounds like iron
    Conductivity signature too close to iron ...

    in counterpart: in all metals
    you will not have anything more sensitive on the 24k / thanks to the 7us

    our reference ring is a fiancaille ring
    18K white gold palladium alloy / very hard to detect
    in 5 years of research we have gained almost 20 cm on this ring
    which is huge at the beach

    as I said on other forums
    Of course, you will gain depth on the big rings
    (Fisher's future joke being:
    you will have to learn to give up targets)

    but most of all: you are going to detect very fine rings
    at less than 40 cm, that other machines simply do not see

    Perfect Manta seawater beach....black sand, big beach parties where lots of folks built bonfires out of old pallets and the nails are everywhere - it would be essentially undetected by others - what with the nails and the black sand shutting them down.

    Please forward GPS coordinates or Google Maps references! Lol..

    Seriously, it looks the early users if this machine are going to be “walking on a new planet” when it comes to gold at the seaside.

    looks like a granddaddy detector but anyways i didn't know 24k and iron have such a close conductivity to not be able to separate, maybe the only way is if in the detector there is a physical piece of iron and little piece of 24k gold nugget, then the signal picked up from the 24k in ground needs to travel to the interior of the detector to get verified in the interior gold tube amp filter chamber of being either a 24k gold frequency or false iron one and then to allow the result of the detector producing a beep on 24k as the detector passes its own gold verification test... who knows?

    Erte, it’s about how PI detectors work. The decay of the signal from targets, measured in microseconds is what matters. High purity gold - large bits - and iron are similar. Lots of stuff on the web about this - look it up, study it, if you still have questions, come back.

    we talk about conductivity signal to make simple
    (all prospectors are not necessarily engineers)

    but if you prefer, microsecond playback time on the implussion delay
    on this reading window
    the 24k is very close to the iron
    too close to make a difference in analog mode

    - a later digital version with a large computing power will allow
    '' 'can be' '' to make a difference

    in the presence of alloy 23 k and lower
    even with palladium / no problem

    no problem either, with platinum
    same pt999 / whose conductivity signature is different from gold

    for the look, again
    the plastic box is just there to test the cards

    the final product, will have a modern design
    very thin and lightweight for a waterproof detector /// with a world first on a waterproof detector ////

    finer and more design than the tdi pro
    for example, I see you have a
    who him, with his big tin box
    really gives a grandfather's style

    I guess my question is, do you really need to go deeper than 12"-15" to get 95-percent of beach gold? If you can spend $650-$900 to get to 95% of the gold WHILE discriminating with Multi-freq, why would you spend $2,000.00+ on another PI?

    I for one loved digging up the real deep old gold and platinum rings with my Aquastar. Because I know many people have walked over these rings but they did not have a metal detector that could detect these rings. And yes, I really like my Equinox 800 but I still want the Manta.

    the price is not fixed yet
    will depend on the strategy of Fisher First Texas

    as I said before, here and elsewhere
    you do not necessarily go digging deeper

    imagine a 18k ring of 15gr
    in limit of acquisition of your detectors
    at the same depth you will detect a ring of 1 to 5 gr
    so you are not deeper = but you pick up more gold .......

    it's the greatest strength of Fisher Aquamanta
    detect what others do not see / thanks to the 7us under 16 volts

    of course, if you like big rings
    you can go further / but it is not an obligation

    and to be ironed, often, behind multifrequency
    you do not pick up 95% of the gold
    there are still more than we can believe
