      ???

      Well so thats it.

      Don't want to be negative so will be careful here,

      but those little wires that come from the hand switch

      look a bit fine for a clod like me who would probably hang them

      on some bush or something and rip em in two.

      So how much money does it cost ???

      That's what we want to know.

        Hi,
        I think you understand it wrong... It's clearly a prototype of the analog version.

        The thin wires you see are probably a power cord from battery to the electronic control box, with yellow panel...but this is sure a proto. Maybe in definitive version would be some spring-loaded extensible cable... like old phones have.

        I think the battery had to be carried hip-mounted or under arm... but not inside the control box like in other designs that are really heavy cause of battery inside.

        Notice also that , from what I read, seems this is the analog version that's different from the true digital one... with MCU.

        So disc is analog from what I understand... this is the point.

        Seems nice as proto but the most important issue with it is if can really disc metals or not and with which level of reliability.

        I also noticed it has manual geb that seems really good thing on any MD , but in this case even more.

        I'd like to see test results for it... and to hear if can disc out ceramics or pottery stuff... that's annoying problem with all my PIs... I hope someone will post these informations.

        Kind regards,
        Max

            Hi,
            so , as I see, the thin wires are for button on the handle... and battery must be inside the box... thing that I don't like much.

            But detector seems robust construction and if does just one half of what initially planned it will be cool having one !

            I'm awaiting for more details... but I know this could be long process... about extensive testing in various places in the world.

            I'm not in a hurry about my next PI so... I'll wait and see , and if worth I'll sure buy one !

            My problems with PI are the dang pottery stuff... and fregments... that I can find in some places... just maybe 10-15% of places I'm interested but some are good places... so it was always boring dealing there with crazy PIs...

            I hope pulsedevil will solve my problems there!

            Kind regards,
            Max

                much better

                Hi bugwhiskers,

                Thanks that is much better !! now I can see the 10 turn pot they were talking about.

                I was like Huh? no controls, anyway not sure thats the best place for them because

                of dirt everytime you set the machine down to dig up goody.

                Hi Max,

                Yes it is for the button, seeing more I guess they could be replaced easy enough

                and some duct tape could maybe help. Ok, it looks more like a detector now.

                Though I guess the "perfect" detector would be Turn On and Go.

                Auto ground and everything.

                But then no endless discussions about how to best adjust the things,

                and if someone calls and complains, just say you don't have it adjusted

                correctly.

                  Hi JC1,

                  Deep large targets produce a signal that is broad. Auto ground balance will very happily null out such a target treating it as a slow change in ground.
                  Notice the knob called RETUNE, it has fast to slow and Manual.

                  regards

                    Hi Bugwhiskers,

                    It depends on how fast the auto ground balance is running whether it will

                    null out or not a deep large target. I do like the names on the knobs, the names

                    make sense to me and I could probably run it without reading the directions,

                    which is how things should be.

                    Glad Dave is getting some help from you (I read) he needs some help doing alot

                    alone. But still probably should have waited before getting too excited about

                    introducing a new detector. People have been asking for years now.

                    I still haven't found a price, sure there must be something on that even an estimate.

                    I also like the 10 turn pot knob, I use four of those on my homebuilt units.

                      Hi JC1,

                      I am guessing that you would at least get 2 Nemesis's for the price of a new Minelab. His and hers. As info that I can relay accurately comes to hand I will pass it on. If you are in a huge hurry you can always visit

                        ok

                        Hi Bugwhiskers,

                        Did a little more reading. Looks like the autotrack is a real

                        track and not SAT which is good in my book, and can be

                        turned off, also good. From my reading it seems that you

                        designed the transmitter. I have a question, on the turn on

                        of the xmitter, is the voltage used for this higher than the

                        battery voltage to get the dI/dt of the coil going? This being

                        done to get a stronger signal on the turn on for discrimination,

                        closer to signal that will be received from the fast turn off.

                          Hi JC1,

                          The Nemesis is 100% Dave Emery designed. You have misunderstood a post on another forum. Questions on "how" the Nemesis works can only be answerd by Dave as there are patent issues to consider.

                            Hey Bugwiskers,

                            You are right, I miss read that, guess you

                            built xmitter to Dave's specs.

                            Whoops. \\\
