    So what! The spider wound coils I have tested were far superior to any commercial coil! Now for the interest of members here could you please answer my earlier questions on coil Q and related matters.And please don't try and run away with your silly diversions! I say that you simply don't have a clue! Now prove us all wrong! Show us all your technical mettle!

      Tell us all about the rigorous testing processes you went through to reach your conclusions Doug, and define the performance parameters that were so much better! Now this will be interesting!!
      I notice you are, as usual, ignoring any queries thrown your way Doug. How about you show us your technical mettle and present the data you would have to have collected to state categorically that a spider wound coil is "far superior to any commercial coil". Just more of your unfounded BS derived from wishful fantasising.

        Patches Junior is the one ignoring my questions! We can all understand why you are trying to protect him! The spider wound mono performed BETTER than any commercial coil in the field over typical gold field ground in Vic and that is ALL that matters!!!

          What coil parameters should I have measured and why?

            You are the one making the claim, Doug, so lets see you actually put up for once. What parameters did you measure to identify that this spider wound coil was "far superior to any commercial coil".

            Instead of talking out your behind with unfounded statements, present what methodology you used and the data collected that allowed you to make the statement you have made. In other words, as you are wont to say, "put up or shut up!"

            Note Doug, I did not say "coil parameters".

              The coil was superior in depth, sensitivity to any commercial mono of equivalent diameter over typical goldfield ground in Vic!!! That's all that matters and all that really counts at the end of the day! What other "parameters" should i have measured and why?

                So you pulled the test results out of your behind. Thought so!!

                  No! Prove me wrong !Please tell us all what data and what "parameters" I should have measured and why! ie please tell us how YOU would go about testing a new coil type ie what testing protocol YOU would follow and why and what " parameters" YOU would measure and why and how YOU would measure them and then evaluate and compare them with existing commercial coils.

                  • Doug,

                    Minelab use high Q coils but most of the science taught here on Geotech relies on low Q coils so would a high Q coil make a significant difference to any of these??

                    Do we see a significant improvement if we fit a high Q Minelab coil to a GS4 GS5 or TDI?

                    You said you couldn't tell the difference when the QED was fitted with a low Q coil but it seems you are now obsessed with high Q coils?

                    We can increase Q by just simply increasing diameter but it seems you aren't interested in this?

                    And this... we can improve Q by using wire with many more strands????

                    And this... we can improve Q with more turns of the same wire????

                    And at the end of the day a significantly higher Q coil requires circuit changes to work properly in a mL PI and a PI detector doesn't automatically sample earlier if we lower the capacitance so no real advantage in either case.

                    You are just nit picking about stuff you don't understand Doug.

                      Doug, for once in your life why don't you answer with science and logic. Why don't you tell the members what coil the builder of that spider wound coil used on his own detector after playing with the spider wound coil?

                        Maybe so parrot But spider wound coils are are far better alternative than ANY of the above methods!!!

                          Its the coil he used!Now please could you be so kind as to answer the questions i posed to you in my previous post! I am sure members here would be most interested in your response as am I. Perhaps it could lead to a standardized geotech aka Paul99=Urbanfox coil testing protocol?

                            Doug, you are the one making the statement that the JS spider wound coil is "far superior to any commercial coil" so it is you who need to justify your statement by detailing your testing protocols and results.

                            At the end of the day, Doug, are you trying to tell us that JS only ever used spider wound coils after building a couple?

                              The onus is on YOU to prove me wrong! You simply can't and it appears you also unwilling or unable to put forward your coil testing protocols!!!! Come on, members here would like this info and as i said it could lead to a Geotech standardized coil testing protocol! How about it? Its no good being critical of a testing protocol unless YOU are prepared to put forward your suggestions and how the testing protocol may best be implemented! I await YOUR testing protocol with baited breath!

                                Has JS tragically not become terminally ill he told me that he was going to use the coil for ALL his future detecting as his interest was looking for big nuggets in deeper ground that could NOT be detected with any current coil/detector combo!!!!
