Newfie, Labrador is part of the Appalachian System, an enormous area of very low Fe content soil. The Makro Racer is a 14 Khz single freq, and works better, much better - in mild soil like in Newfoundland, or Europe, including and especially in the deep south USA, the British Isles, Western and eastern old Soviet Block, etc. Oregon soil is by and large BRUTAL compared to the milder soils elsewhere that you speak of, and Jeff lives in Oregon. We got hit by the meteor belt, the meteor showers a couple of million years ago. Labrador clear down through Florida did not, nor did Europe or the British Isles, or Scandinavia or the middle East. . We often have as much as 1/4+ of our soil here as iron filings, Labrador does not, nor does anywhere else. I know of places near here where a single freq does not work at all in any way, and a multi-freq just warbles or howls.
There is something rather suspicious about your report so please help me out here, because it is not making sense to me at all with the report of more (and) so many finds being made with the Makro, because it's about mathematics, including the higher VLF circuitry ones. Did you know that the Fisher F75, the Nautiluses, and the T2 and Fisher 1270 and the Tesoro Tejon have all reached the pinnacle of depth in a (higher) single frequency machine? I mean in engineering terms that they have reached the end of the spectrum of diminishing returns. We simply cannot go deeper than any of those, they are at the wall, the end of the journey. Radiated magnetic or electrical fields eventually reach the end of the run, and then in order to go even a hairline more they have to have the voltage increased by 400x or more, and that would require a 1200 pound battery, at least. There is no magical number beyond that, it's the end of the race, all the writing has been done, ain't nuthin' left but the cryin'.. Filters and voltage control or resistance or capacitive discharge changes do not improve anything either, nor do types of coil windings, or more powerful transformers, not even stacked coils or 3 tiered ones, etc. In fact, the Macro can not go deeper than the above with the same size/type coil, and it is not more capable than the others either. The only thing that can change its performance - is operator performance or skill, that's all. But more than anything else, European detectors commonly do (not) present anything more or better than American detectors both using same size/type coil, they just present them differently on the panels.
Hence my question: Why would the Macro produce more or better results when the other detectors have already reached the end of the line in performance? And my next question is. You do know of course, that Eastern Europe detectors (commonly) have more malfunctions in their electronics than American ones, right? Look what happened to the Teknetics line from Bulgaria or the Czech Republic for example, it basically disappeared because it was insufficient here and broke down more quickly and almost immediately at will, and eventually people discovered that it got blown away by other better-made, more reliable American detectors too. . This is why I suggested to not be someone's test rat. Waaaaay too many people have bought detectors from Eastern Europe and can't even find someone to service them any more. Most metal detectorists aren't like me, I can repair one, but most folks can't. Everyone should beware of anything new, you could be sorry otherwise. Don't take the chance, let someone else try the new stuff, not you, you are more important than that, and you aren't somebody's test rat either.. Wait and see instead before you buy, new isn't always better, it's usually just different.
