Skookum Posted July 12, 2021 Share Posted July 12, 2021 I believe I've answered my own question above. The SDC 2300 precursor, the F3 Compact, was released in 2011. The SDC 2300 was released in 2014. I've been thinking about the tech listed in these specifications. The marketing says the MF5 combines the advantages of both PI and CW. However, with 4 frequencies between 5kHz and 75kHz, doesn't that just sound like continuous wave multifrequency scanning after the manner of the Equinox? The SDC 2300 was 3kHz PI MPF.

Steve Herschbach Posted January 10, 2022 Author Share Posted January 10, 2022 I found this new marketing blurb very interesting...... "Minelab’s unique Simultaneous Multi-Frequency Digital technology results in the MF5 providing superior detection capabilities by combining the advantages of Pulse Induction and Continuous Wave technologies." https://www.minelab.com/usa/countermine/detectors/mf5-military-clearance-landmine-detector-by-minelab 4 1 2 Link to comment Share on other sites More sharing options...

Perhaps one with some sort of ZVT? GC Link to comment Share on other sites More sharing options...
rvpopeye Posted January 10, 2022 Share Posted January 10, 2022 SDC with both types of detecting in it..... Two dozen factory training videos ! Should be some hints there .. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted January 10, 2022 Author Share Posted January 10, 2022 Or just Multi-IQ, and a person in marketing doing what they do. Just a note on progression. The SDC housing originated as the F3 Compact countermine detector, in response to a specific government military contract, that had a design spec for waterproof and folding. The Garrett ATX was spawned the same way - same contract actually. Both companies made a waterproof folding mine detector first. Then, to get more money from the expensive housings, they stuff a consumer PI in them. So for Garrett is was Garrett Recon first, ATX second. For Minelab it was F3 Compact first, then SDC 2300. And next up the MF5. Which despite the marketing blurb I really do think it's just Multi-IQ, a stripped Equinox ferrous/non-ferrous circuit, stuffed in the F3 Compact housing. Sadly, I've learned to be pretty cynical when it comes to reading between the lines in marketing info. Read the operating manual and see what you think. https://www.minelab.com/__files/f/444357/4901-0373-1 Inst. Manual, MF5-EN_WEB.pdf It does have a cool new coil with a unique target response: The biggest thing I see is the frequency spread, which tops out at 75 kHz versus Equinox 40 kHz. So it is optimized for finding the tiniest firing pins or thin wires.... and might very well make a nice small nugget VLF. If you wanted to pay the price, and swing the weight, for what would still be a VLF detector. 2 1 Link to comment Share on other sites More sharing options...
Jeff McClendon Posted January 10, 2022 Share Posted January 10, 2022 DETECTION CAPABILITIES The MF5 detects metal and conductive targets, including fine wires and carbon rods. It provides indications of ferrous and non-ferrous targets, carbon rods, and fine wires. The MF5 is able to detect targets in all types of soil, regardless of mineralised content, and can operate in environments of high electrical interference. Carbon rods????? Can operate in environments of high electrical interference????? Multi IQ that is on my Equinox doesn't like EMI although EMI doesn't bother Vanquish very much, but I guess the use of the word "can" is somewhat relative.

Steve Herschbach Posted January 10, 2022 Author Share Posted January 10, 2022 I just added specs and a comment to my post Jeff, while you were posting. It may be that as a military detector the design has extra shielding. One thing they can't have is interference screwing up mine detection and killing someone. The new DD coil design may also have something to do with it. Perhaps a cancellation coil? 1 Link to comment Share on other sites More sharing options...
Jeff McClendon Posted January 10, 2022 Share Posted January 10, 2022 That coil design looks really interesting. Anti Interference ??? coil that ramps up power over a target in detection mode combined with 75 kHz would definitely hit some small targets.

Steve Herschbach Posted January 10, 2022 Author Share Posted January 10, 2022 I'd like to try nugget hunting with one, but not enough to buy one. If they can even be had outside military channels. But the circuit could be the basis for whatever replaces the Gold Monster some day. If ever. Minelab said no more single frequency, and that includes any future gold VLF models. Nugget capability on Equinox in Multi was almost an unlooked for accident. I can only imagine a machine tuned specifically for nugget detecting, and this machine looks like something very similar. But ditch the housing, please! 5 Link to comment Share on other sites More sharing options...
