  • Aquasound

    hello, can anyone share a schematic? some pics I see here http://www.treasurenet.com/forums/tr...ew-2250-a.html
    unknown one for me. I read it is best for salt water and based on TR way. that is all.

    This detector was manufactured 2 years ago for me. They are custom built by a couple of very talented people in Florida and modeled after a Nautilus detector. The technology has now been around for quite a while, but depth and sensitivity in the right sand cannot be matched This detector is virtually brand new and comes with both water coil and land coils and each has its own shaft to make the transition from land to water much easier. Paid $2900 new.

    The Aquasound detector is a very high powered TR unit (52V to the coil in high powered mode and 32V in low power). It has a custom built waterproof case that is a very strong, thick walled, clear polycarbonate (Lexan). The Aquasound must be used away from any black sands. The cleaner/whiter the sand, the deeper it goes. Tuning the machine is also critical (this is usually maximised after about 10 minutes of use). The coil loves to be submerged in water where the electronics can be really wound up.

    "Good" tuning will give you a depth of 18" but with "Great" tuning you will see 20" plus. The tuning then incorporates getting both "Null" controls centered really tight and then the 10 turn volume/threshold down really low.

      thanks lots Don. one russian asked me about it what I have not. I see preamp built-in coil, some like as Nautilus.
      still one pic of AS.

        How to get 52V HI POWER TX mode out of Don schematic?

        Thanks Don!

          the high voltage is getting in the specific winding of TX, it has a point for generator connection and end wire where is HV. something
          like if you will take a fishing rod and begin to swing it - on its end you get more amplitude at its very end than you apply some low amplitude to some rod's begin part.

            Oh yes, I see. We get out it on autotransformer way. Thanks to point it out, KT315.

            If you plan to make some PCB's, I will order 3pcs.

              yup. autotransformer with 'free' (never nowhere going) end. you can see this decision in books of Andrej Schedrin, he did TX for a deeper/two box by similar way.

                What is your comment on my question in previous post regarding PCB's?

                  smity sees and smity will make =) I do not see full data on the coil. all I read in this thread http://md4u.ru/viewtopic.php?f=94&t=8150
                  that the coil is winding by very thin wire. this is all.

                    You can get an "idea" from the Nautilus patent. I built one of the circuits just for an experiment a few years back, and it did work. I learned a lot just by building the circuit on page 1. Very interesting to see how the feedback method works (phase and amplitude). Notice a lot of similarities to the Aquasound here?
                    I was looking for specific coil data as well.

                      Following discussion on those Russian forum: as far I know Bigfoot is not RX Figure 8 coil, but TX Figure 8 coil. Or I am wrong?

                        do not know sure. big foot was been discussed in another thread, Carl there answered something on your similar question that I am not able to find momentary.
                        if you losed this info I put here again those pics from the thread. you see here clearly at pic RX has 8 config (the data gotta from Jurij Petric, ciklon; not mine).

                          What mean this remark in AquaSound schematic: "VOL.250Ω"? Or it is maybe "VOL.750Ω"?

                          Is it about total Re resistance including transformer primary resistance or something else?

                            Guys
                            you again and again ask me to give full pocket on some detectors. again again and again.
                            like i am a wonderfull genius keeping all (in this case bulgarian genius). i have just THAT YOU HAD SHARED, i do not have ABOVE it.
                            if you do not want to share an info - i do not get the info. IS IT CLEAR?
