  3. I agree with Steve--its the SMF platform and how it relates to ground and targets--a broader cause. Hope the broad-based testing model helps you with your next experiment. But when I say "jam my books down anyone's throat" I mean the detecting public--not anyone in particular and it's a bit harsh to frame it that way. When I started basic theory and skills werre the first thing we learnt. Now it's all settings, "tweaks" and watching for numbers on a screen. Best of Luck. cjc
  4. 32/ Appendix III: Testing the Manticore as You Hunt Trial, error and testing is the “meat and potatoes” of becoming accurate with the Manticore. The more prepared you are from testing under controlled conditions the better armed you are against frustration in the field. While there are lots of test models that rely on cross-comparison between targets buried at various depths, the model I favour is based on the idea that to be certain of something--you need to try your best to disprove it. The idea is to push the detector until it stops performing. You then have a good idea of when this is happening in the field. Begin with a buried target of the type you hunt. Then try some basic experimental design. Let’s begin with some definitions: 1/ Independent Variable: This is the factor that does not change. 2/ Dependant Variable: This is the one that does change. 3/ Intervening Variable: This is the one that causes the change in the Independent Variable--the middle one--the “monkey wrench.” So, if you take a basic test on our buried target, the ground conditions and target itself are the Independent Variables--unchanging--for now. The signal tone is the Dependant Variable. (Loud / quiet / broken, no sound would be some possible outcomes…). Then bring in some Intervening Variables: These might involve increasing the Sensitivity, changing the Recovery Speed or Ferrous Limits--it’s your choice. This model gives you an organized framework with which to test not only single Intervening Variables--but also several at one time--to begin to understand the interactions. Conversely, next--the ground conditions or type of target themselves could be used as the Independent Variable (for example black or normal sand as separate trials or gold versus silver) --with an individual setting or complete mode as the Intervening--and again--the audio tone as your test result (Dependant Variable). While all this may sound a bit stuffy--it’s the way to get a good clear understanding of what the Manticore will and won’t do in the various modes and settings--under different actual conditions. This is much more “hands on” and fluid than Simple “on the fly” experimental design is a good way to learn more about your machine as you hunt. some artificially created test garden in your backyard. As well--these are tests you can perform as you hunt. Another way to do this is to “start with an in-ground signal and try to make it worse.” This might involve changing modes, increasing the Sensitivity, or changing the Recovery Speed or Ferrous Limits. The great thing about this kind of testing is that you can begin with extreme settings and learn what bad tuning sounds like. This tells you what to listen for in more typical situations. Using this model some interactions to look at would be how: · Again, the general principle is that when you move too far from the pre-set range with any of these controls--there needs to be compensation with one or more of the others--or at least your sweep speed. · Remember, begin with extreme settings to create a “benchmark” for each negative effect. This gives you the clearest data--models to watch for in the field. Being able to make these “ear to coil” calls is the way to accomplish a balanced signal under any conditions. You first have to know what an unbalanced one sounds like. Besides signal tone, meter stability is another Dependant Variable to experiment with. Then of course there’s the old test garden Dependent Variable of depth… · A more complete list of audio characteristics to look for would be: wide / narrow / “peaked” / loud / faint / clipped / weak / “skewed” (forward or back) / flat / blaring / “squeak” / relationship to threshold…(is the response “flat” or does it “jump out?)” · (I would include “bittyness” here but that’s more of an “in-ground overall signal characteristic). All of these can provide useful target information and inform your settings tests. The key is to begin with extreme settings so as to be able to recognize the various performance changes. This will help to develop your tuning skills a lot. From: "The Minelab Manticore: Tips, Tricks and Settings" by clive james clynick.
  5. What Im saying is that a nickel is more suseptable to detection problems that are a result of sensitivity too high, bias too high, EMI or just bad ground. In effect the more sensitive and exact a machine is--the more this is true. Could also be a "bleached" nickel. Try another target before deciding that the Manti--with all it's choices and fidelity is oh-so- terrible--andthat no adjustment could solve the problem. Your test is interesting, but not conclusive. This why Im about sick of trying to jam my books down the throats of people who don't think that basic detector theory is of any value. As machines become more involved people want to rely on the tech (presets for example) alone without having the broader understanding of ground, detection, detector features and target types. When I use a term like "signal balancing" not many even know whats being balanced in relation to what--why bother? They are thrashing about in effects, as if they were causes. cjc
  6. Nickel is a partly magnetic coin. That's not to say that a a magnet will pick it up, but it's properties are very, very different from gold. A detector which is engaged in processing out inconsistent / random indications such as the ground will have no problem mistaking that type of target for the background. Really more of a demo of target types than anything to do with how good the Manti is--unless you hunt exclusively for nickels. A little basic theory goes a long way. A detector does not punch though the ground to detect a target--it separates the two. Sometimes the two are near identical. Overall the ground's signal is larger, thus, the higher you turn the machine up, the less separation you get on this type of target. Try testing your VLF indoors and in partucular, not what happens when you slow it right down. At a certain point it has time to make the distinction between EMI and target. The ground's "interference" is lessor--but no different. Where you have a lot of electricity in the ground--such as near a big hotel--this masking is even greater. Not to say t hat a nickel is that bad of a tester--just that its not all that distinct from the ground. cjc
  7. I would also add that it's not just fast salt and black sand that cripple VLFs. Its the interference created by inclines, hills, seabed contours, weed beds, different types of material under the coil--any number of things. There's just no contest. I too have engaged in this same wishful "VLFs have gotten so powerful" type thinking but found it to be not true. At the same time there's such a thing as benign conditons--or places where trash targets and the general depth of what there is to be found make VLF the way to go. cjc
  8. All told I would have still given the good old DF more weight in this discussion in that it just has a lot of target information in the tone and is as deep as anything out there including the TDIBH. Ya it's got a bit of crackle but this is the interraction that makes it deep. Ya there are some great VLFs out now but in salt water or black sand there's still no contest. None of these MF detecctors handle fast salt all that well. Even a pulse with a small coil still needs to be balanced out to perfrom well in these conditons--proof positive that VLFs are faring much worse. The Impulse AQ is the creame of the PI crop but not for the PI novice--The build choices are not all good (Vishay pots) and other small bobos make it a troublesome detector to run. Its a machine with "rites of passage" that have to be surmounted to finally arrive at a place where you have had components fail, broken a few fragile bits and are at last ready to swing problem free. Over all though--a superb circuit and exacting service from FT. I have two and two DF's -- without them I would be competing on a level field and these days that can be hard. With a pulse, the worse the conditons the bigger the advantage. cjc
  9. I don't understand your question or the context--what post it's in response to. cjc
  10. you read my mind, Tony. I was just going to put up a post asking if anyone had had the 15 in to salt. NOX was pretty crappy overall just not handling the fast surf and contours. To be fair, 5 tone spreatd the signal out a bit and made it less chattery. Keep us posted... Regards clive
  11. Wow--good to know. I'vve got the AQ small coil cable / plug set up on the bench to solder and walk a wide berth around it...soldeing is my shame....lol cjc
  12. awfully small solders in those plugs--don't think I would try a build. Thanks for the specs though.
  13. This is agreat question. He doesgive some specs. I want to know the same thing . cjc
