Testing detectors, coils ... on various mineralized terrains - I give it some time ..it allows me to find different detection contexts better. Because I consider it a major drawback of the VLF detector .. IN "Low" mineralized terain 1-2 Bar Fe3O4 .. Item N.2 ..very small 3x5mm"O" gold segment- 0.05grams buried at 10cm=4" in the ground is a challenge for any detector .. Small 13mm Silver earring N.5 is 20cm=8" deep .. And small 13.5mm -0.45 grams of silver hammered coin Denar- is buried at 23cm=9" deep in the ground .. The deepest coin is"50eurocent"buried in a depth of 37 cm...=15" ..in ground.. ------------------------------------------------------------------------------------------------- 2.The second test is a test IN" Medium and Highly"mineralized = 4 Bar Fe3O4 .. ceramic granulate "Liapor" which is stored in a 350 liter plastic box. ----------------------------------------------------------------------------------------------- 3 .Test in "Extreme" mineralized 50L "7Bar Fe3O4" Black Sand box...= 4% Magnetite.. ----------------------------------------------------------------------------------------------- The detector is tested on a variety of coils. This will determine the optimum coil for a given type of detection, as well as the advantages and disadvantages of a given coil / detector combination. --------------------------------------------------------------------------------------------------- Fisher Impulse AQ.... and reach in Tests.... I consider the system of tests in the squares and the storage of test objects to be a well thought out and difficult test In order for the detector to pass such a test ... the detector must be very sensitive (range-signal strength) to gold ... and also well separated in the iron../ I myself did a similar "nailbord test with a gold ring" under the nails ... which he put here here some time ago Rick .. so I know ... how it is difficult to unmask gold under the iron .. More information about the tests, but also the type of terrain .. on which Fisher Impulse AQ can work .... can be provided to ALEXANDRE..

The sensitivity and range of the VLF will depend on the frequency and also the real ..- Correct / not maximum / detector settings for the given degree of terrain mineralization .. So feel: low-mineralized terrain approximately 85-90% reach, / compared to airtest at the same settings / moderately mineralized terrain 75-80% reach, and about 55-60% reach in extreme mineralization Of course -from real-optimal Vlf detector setup for given terrain type. So the actual performance of Vlf in heavily mineralized terrain can eventually be only 35% compared to the maximum detector setup ...- which you cannot use here .. The detector frequency alone gives you a certain degree of sensitivity for the conductivity of the object. Higher frequencies are still several times more sensitive to low-conductive objects - for example, gold ..Multifrequency maintains a more balanced sensitivity to all types of object conductivity Therefore, I consider a PI detector with good iron discrimination as a much more powerful detection tool in difficult terrain conditions than a VLF detector. So the new PI detector ..... Fisher Impulse AQ, can say a lot in deep detection ..

I mean, for example, this moment..where's Vanquish reacting to the brick .... but also the video test Bricks and Coins. I wonder how Vanquish 340 works on Coin, Jewerly. Certain forms of discrimination at / 0, + 1, + 2 / in Equinox contribute to a better non-ferrous ID, as well as to a better tone of non-ferrous tone ... in mineralization .. My Vanquish 340 should be available in about 7-8 days .. so I'll do some comparison too ..

Flyfish... From the video and comments is clearly from the Vanquish 340 m and fixed Ground Balance ... Signal bricks is on -9..in the zone of small iron and minerals. In this case, it would be worthwhile to try to use the Coin program or Jewerly-programs that have some degree of discrimination against iron ... The test is also based on the reduction of sensitivity helps to better detect coin /1kopiejka SSSR/ under mineralized Brick .. I suppose Vanquish .. when the sensitivity decreases to change RX Gain .. and the detector can better target the slow movement of the coil.

Greetings Sergey -Asgo... ,, will be interesting to learn about AKA detectors specifically about Signum and the New "Intronik" multi-frequency detector ..

491/5000 Hammer coin I found on 5 ID ... near the coin was a piece of aluminum foil that gave 4 ID. After digging it had a hammer coin of 7-8 IDs. I use Park2 ../ in this program, conductive ground may reduce the salinity of IDs. Park1 program is resistant to saline and conductive ground. Try to compare Park 1 / for conductive, saline ground / and Park2 / for iron-polluted ground / Try to compare it with recovery speed 7 and discrimination set to +2 ...

aufarmer ..... Try a pack with Ni-Mh accumulators 2-3 times in a row charged / leveled / with a 24 hour charge interval .. Sometimes it helps .. The power of the pack is still dependent on 1 cell accumulator .. and each of them must work properly .. I think that....One the Ni-MH cells in the "packet" still has a low residual charge voltage .. when the "seem" - fully charged- while charging ... but its voltage in a few hours .. then quickly falls .. So you need it fully charge -to have the right voltage and power capacity .. I use Whites SpectraV3 and V3i ... replacement 3x 18650 Li-ion pack ... but for other brands of detectors ... I use 1.2- Volt AA NI-Mh... and also 9-Volt.. Ni-Mh accumulators ...

Personally, I see an increase in TX voltage of 54% as a very good step ... High TX voltage also means very well balanced coils .. especially for very small sizes, ..for medium coil sizes and large coils, these demands are less . .I believe Whites with the new 24K/GMX is on the right track ... Spectra V3.. My experience with TX bost ..... / Tx Normal= 10Volt - increase to approximately TX Bost ON= 25 Volts / according to my estimates, measurements Whites Spectra V3, I... prove at least 3 facts: Fact1...Small or medium coil .. strong sensitivity and range increase on the smallest objects - the detectors are in normal TX mode very weakly detectable or have a weaker detection range / or are practically invisible .. The range can be increased from 10-15-20% .. even to 90% - for very small - weakly detectable / invisible objects. In the test field I have buried at a depth of 10cm ..3x5mm -0.05 grams of gold "O" segment .. Spectra V3 detects it well in TXbost ON at 22.5khz .., Even on the 3F multi vTx Bost ON to detects- but more than the Borderline signal .. When Tx Bost OFF -un I get no detectable signal .. ..control airtest on the same detector setup confirms field tests: On the : 1. Frequency 22.5 Khz is range = 11-cm in normal Tx. and 12.5-12.8cm in Tx bost ON.=+15%more 2. On 3F multi-F .. is range = 8cm normal Tx. and 10.3cm -10.5cm in TxBostON.=+30%more Note: the detector which reaches the gold "O" segment at 12cm in the airtest - gives a "good signal" to the same Gold "O" segment buried at 10cm in a slightly mineralized ground..../Always count with at least 10-15% loss of depth in low mineralized ground-... compared to "airtest"! /. ---------------------------------------------------------------------------------------- Fact 2 . Using TX bost ON - when "properly RX Gain"-not too high Rx Gain -is .. ... effectively eliminate EMI problems while still maintaining sufficient detection depth. Fact 3 . It is generally known that when using large Coils / size 18 "/ .. the sensitivity and the impact on very small objects and also small coins will decrease significantly. One way to achieve real good enough sensitivity and reach ..to 1.For these "Very small "objects to 100-150%.. /gold "O"segment-N.2 /-from 1.2cm Tx Bost OFF..to 3cm !!!..in Tx Bost ON.and... 2.And .." Small" object to 50%/gold earings N.3/-from 12cm -Tx Bost OFF... to 17.5cm !!! in Tx Bost ON ... 3.To Medium ,or Large object.. .the range is approximately. 10-15% to 20%max is to use TX bost ON .. Another important benefit of using Tx Bost ON in the Large Coils I've already mentioned ... ... is the better Elimination of EMI .. ---------------------------------------------------------------------------------------------- Photo 1...

Garret may be surprised for this year .., Wide experience with detection technology... he has already managed a long time .. I would suggest to focus on the new powerful GTI class detector ..

I found an interesting YT video Vanquish 340..This makes it easy to convert S -Shaft to direct -Shaft ...For example, if you ever want to do that ..I consider this a sophisticated Shaft design at the Vanquish ...

Personally, I think Vanquish will use an optimized Beach1-like program ... as a basis ... And that's why it works very well on the beach ... and without any special program just for the beach. But of course it is only an assumption .. If I have Vanquish 340 in my hands ..... I measure its TX on an oscilloscope ... and via FFT and take a picture of the frequency of the program ... Advantage and Point Vanquish 340 is in the fact that in "One Program" setting it handles different types of field conditions Detection..and has a good ID in depth .. -The main advantage of multifrequency .. And while it looks ... he's doing pretty well .. Equinox 800 Beach1 program- FFT -TX frequency Equinox 800 Park1 program TX frequency- FFT Equinox 800 Park2 program TX frequency - FFT

Vanquish 540 pro package is not a bad purchase if you decide to sell a small coil. ... so I think ... on WW1 and WW2 you will need especialy to use a large coil...

Do not search the Wanquish 340-" entry detector Level" all available and adjustable features ... that have Top Detectors available .. Fixed Iron Bias doesn't mean you can't detect in the iron ... but on the contrary eliminates a lot of iron waste --bottle caps,nails..... so you can detect "Good signals" Ferous and Nonferous -faster if it is sometimes at the cost of deteriorated separation ....but not ... in every case ... In the program ... "Allmetal" can search all kinds of objects .. Many good detectors on fixed Iron bias and allow effective detection... Iron bias - is not just a filter of iron ... it is a filter of very short signals - from objects, mineralization, Emi ..

Mojave with concentric coil practically does not work well in heavily mineralized soil. but with 6X8"SEF DD coil works very well with reasonable range ,,, even on Low setting GB.... But of course it does not detract from the quality of detection Minelab Vanquish 340 ,,, and I consider the auto "noise cancel" another big plus .. Thank you for the information...

Thank you for your direct answers .... Steve Herschbach ... I also thought I could resist buying Vanquish 340 but for the price / 238 euros / with free shipping I just clicked on it .. It is unbelievably to what price level the multifrequency got .. with advantages which offer .. Jeff McClendon ... Yes Vanquish also reminds me of Tesoro Mojave Multifrequency with numeric ID Displays. Simple, ... easy, yet efficiently in a variety of terrain . ...practically the detection range of 0.2 grams of gold per 3 "in the ground is considered to be excellent sensitivity Coils..now I know the coils are not interchangeable with equinox ,,, but from the Minelab marketing point of view.... I understand ... 67GTA .... Thank you for the answer ... I had the impression that some small silver coin was ID a little higher, but on other items enough to agree with Equinox .. The..detector Vanquish 340 seems to me sometime in the middle of January ... so I also compare with Equinox and write something about it ..

Of course, I don't expect performance like Equinox ... but the multifrequency and sensitivity and impact on small targets, and the accuracy of the ID at Vanquish, I think, will be good enough for the price. I also like the 7x10" coil size .. because there's something between the 6 "coil ... and the 11" coil at Equinox .. so the Vanquish 340 will be a great addition to my Equinox 800 .. I ordered it... Still some ... from some tests on YT .. I have the impression that Vanquish gives a low conductive coin a higher ID than Equinox .. Can anyone confirm it? .....

Upgrading to new firmware for Equinox ... takes about 2-3 minutes max ... You can always return to old 1.5.0 firmware at any time .. for another 2-3 minutes ..

8-9 "coil on Equinox would be great .., well I don't understand why minelab has not yet made it ... when the competition has me. According to me the advantages of 8-9 coils: 1.Excellent 2D and 3D separation while maintaining excellent depth ..8-9 "for round coil ... is the size of coil where it begins to separate perfectly in the iron ... 2. Sensitivity to small objects., And possibly improved ground mineralization work. 3.Light weight = Better balance and excellent handling of Equinox in difficult-to-move conditions. 4. On this size of coil we can count increased resistance to Emi .. ...EQUINOX deserves another good coil ..

Mike....., I also bought the same BE Q700 a few years ago ... working on a 9V battery ,,even at maximum detector audio settings.... but giving an extremely low level of sound ..., I ended up experimenting again .. I wanted to limit the volume of the iron sound. I think this equalizer needs a "Line output" .... from the detector, but the detectors have only "Headphone output" . ...when connected to my laptop, the Beq 700 is working a dot louder ..., and can adjust the volume of different frequencies... I consider the iron volume control to be a pretty important setting for some metal detectors ...

I think the problem is that it is just a preamplifier, so you also need a headphone amplifier. https://www.amazon.com/Festnight-Preamplifier-Adapter-Control-Acoustic/dp/B07NYCRK1D

Abenson ,thank you for the test,..... you have done really extensive and rigorous Vanquish testing ..: 1. The results of the Tests in separation suggest that Vanquish has a low iron bias setting ... still a relatively strong rejection of the iron. Stronger Iron Bias settings are responsible for less good separation .. it's strongly visible in nail and coin tests when in one line ... This setup can make an otherwise fast detector pretty slow .. even on a small 4x6"coil... 2..Recovery speed recovery also like to 3-4 recovery speed max .. maybe 5th according to the program. This is also suggested by the hard work and and less deeply detection of Vanquish in tests on heavily mineralized terrain ... 3.Tests in heavily mineralized terrains could help set discrimination to 0 or better to 1. At least on Equinox, it works similarly to "Iron volume" ... + but can also correct incorrect iron "VDI",,,, to better"non- ferous VDI"!!!

In the 1-3..to4bar Fe3O4 mineralization, the 13 " DD coil will have an advantage over the 11"DD coil in terms of depth detection. Every inch is good .. because it means a good ID, of course. . At higher levels of mineralization, the results are balanced .. and at 6..7 bar Fe3O4 mineralization you will get better results on an 11 "coil or a slightly smaller coil./5x10"DD, 6x8"DD coils/.. In very small coils ... a like Nel Snake 3.5x 6.5 "DD.. this size coil you prove to reduce the level of mineralization-several times..for detector electronics......But deep reach the 3.5"x6.5"DD Nel Snake coil.. may not be as ideal deep..on coin size..... as in the case of coils size 5x10" or 6x8"DD ...I'll be deeper..

If you have a sharpshooter, which is close enough to 11 "DD standard Fisher coil .. F44 has ground balance ,,, then I would go to 13" ultimate .. ".. deep and light coil ..
