New metal detectors Fisher F75 V2.0 and F75 Ltd V2.0

The1st and oldest company among metal detectors, founded in 1931 near San Francisco by German physicist Dr. Gerhard FISHER, is now coming out with a major innovation of its best and most powerful detector F75 a F75 LTDThe new versions of these successful and popular models with the Fisher F75 V2.0 a F75 Ltd V2.0 bring several technological changes and improvements that result in especially quiet operation and unprecedented stability even at high/maximum sensitivity settings .

The credit for this goes to the DST system - Digital Shielding Technology; in English it would probably be best translated as digital shielding. This anti-noise filter is mainly used in places with high levels of EMI - Electro Magnetic Interference. It is encountered wherever there are sources of this interference. In general, these are all transmitters, whether TV, radio, telephone, high voltage sources, train tracks or electric fences. But there are also more tangible things like microwaves, television and radio receivers, fluorescent lighting and even ordinary mobile phones.
For those who believe, or have experienced, that any filters and filtering can, under certain conditionsdetector's performance/depth of field and therefore does not want to use any filters, there is a simple option to turn the DST on or off. This is done by selecting either software version 9.0 (DST on) or 9.1 (off ) during the reset process.

The second new feature is the addition of a super fast program, Process FA, designed to search sites with high concentrations of ferrous waste. Its main advantage is the excellent and unparalleled separation , with which comes the search efficiency. The disadvantage is that this program is not as deep as the others, which is of course not its purpose, because on such sites we findThe main purpose of the search on such sites is the possibility and ability to find small objects disguised by iron, such as coins, jewellery and fragments thereof, and old artefacts. In other words, a prospector must know what he is doing, but in addition to that he needs a good metal detector with the capacity to undertake such a task.

A useful innovation that most diggers will welcome and use is the FeTone™ function.After the variable 2F tone, 3 more variants are added with different volume for irons, namely 2h (approximately 70%), 2L (40%) and 2o (0%). The ability to mute your tone response for iron by 60% (this is the value I found when testing the prototype F75 Ltd V2.0 I chose and liked) and let the color tones sound full, is a feature that makes the upgraded metal detector F75a quiet and friendly worker and friend.

The last interesting change from the existing versions of the detectors Fisher F75 is the ability to select the tone pitch for non-ferrous metals, not only in ALL METAL search mode, but also in DISCRIM. In the current models, although the tone height can be set in the right menu column of ALL METAL, this setting applies only to the All-Metal search. F75 V2.0 a F75 V2.0 the pitch setting is also transferred to the DISCRIM mode and every modern treasure hunter gets the opportunity to select the tone of his own choice and preference.

Before I started writing this post, I spent a total of about 8 hours testing the new detector F75 Ltd V2.0 in the field. Firstly, I tested how it behaves and what it can do in a sandpit near the house where we live and secondly, on the weekend in Slapy, where we have a cottage right by the water. It is normally only about 20 meters from the Vltava river bank, but since the river is lowered by about 2-4 meters every autumn, the dam looks like a drained pond in many places with a gentle bank. And this is exactly our case, thanks to which the water disappears to a certain extent every winter and one can then walk through the former fields, see the foundations of the buildings flooded by the dam, theinto one of the small bunkers built before the war to protect the crossing of the Vltava, and in our case even walk along the old road once connecting two villages on the opposite bank of the river (there used to be a ferry at the end of the road).

What this means for every chronic digger I don't need to elaborate further ... For me the drained dam was a great way to test a brand new metal detector. It made me feel a bit like a knight, but unlike him I was not holding a sword in each hand, but a metal detector. Since I've been walking around with F75 or "Eltetech" and I think I know it perfectly, I wanted to try it out for myself and see how it stood up to the new F75 Ltd V2.0. Every "colour" signal received was responded to by my proven Fisher F75 LTD I marked and then checked with the new F75 Ltd V2.0. To avoid the possibility of one of the detectors being more sensitive and not picking up some small object (fishing lures of all sizes including half-moonhooks, glitter and their parts, carabiners, rings and other small items left by fishermen and their rods, as well as coins of different ages, buttons, etc.), after a while I tossed the detectors and first marked the targets with F75 Ltd V2.0 and then verified them with the old LTD.

And how did it all turn out? After this proper testing I can say that both 2 models, both F75 LTDas well as the new Ltd V 2.0 have the same performance, the same depth capacity, comparable separation capabilities and the efficiency of the motionless Pin Point tracking. Not to forget - I set both detectors the same way and to the following values:
Sensitivity = 80
Disc. Level = 1
Notch = 1 (off - never on)
Tones = 2F
Process = JE
Threshold = -1

When searching with your F75 though, I usually use the dE program and then use the Disco to turn on (0-4) or off (5,6) the preamp depending on interference and circumstances . I don't often use the JE program, precisely because the preamp is still plugged in and I can't change the level of interference that easily. And this actually gets to the biggest difference between the two versions Fisher F75. Running the new F75 V2.0 is so quiet thanks to the applied DST technology (even at maximum Sensitivity) that there was no need to turn the preamp on or off by adjusting Disco 0-4 and 5+. With the new version V2.0, it is therefore easier to set up and you don't have to think so much. Program JE means the preamplifier is on and dE means off. But I couldn't find this anywhere, so I wanted to check with the manufacturer to make sure that I'm not mistaken and that this is indeed the case. So I wrote to the head of the company Fisher Research Labs First Texas Gene Sculli, because he was one of the international testers of prototype detectors. Fisher really interested in me, he called me back a little while later. We discussed back all the features and processes, what to set up, etc. However, he didn't know the answer to my question about the preamplifier, and neither did Mike Scott, another one of the outspoken practitioners whom many of us met in person at Mr. Search 2013 and 2014. Eventually he promised to go directly to the developers and ask them. When he wrote me back a few days later and told me that I was right, I felt like a master of the globe for a moment and might have cracked up if my daughter and her violin playing hadn't distracted me in the meantime and helped me sober up. This is just to explain the reason I tested both metal detectors in the JE program, although I normally search in dE. But I wanted to test both detectors with the preamp on, hence the higher power and range, hence the JE process setting. By the way, anyone who has a detector Fisher F75 has and "knows" how to use it, knows how really important is the mutual adjustment of Discu and Sensitivity in DISCRIMINATION mode, or even Theshhod in ALL METAL.For the new F75 V2.0 new METAL, this is more or less out of the question, although we will surely come across some other tricks in time. Finally, if I don't want to look like the usual test dumbass (and there are enough of those on the internet, so why extend their ranks ...) I should at least mention what I like about the new upgraded V2. 0 detector Fisher F75 Ltd I don't like, dislike and what I could say seems worse than the current model. I can't really think of anything major, except maybe the price (which will be higher due to the export and sales prices - unfortunately). F75 V2.0 it will cost CZK 26.990,- and F75 Ltd V2.0 then 29.990,- CZK). And then maybe a little bit and the Discrimination feature - the differentiation of metals. But this may well be only my subjective view.

I dare to claim that my detectorFisher 75 I really know ... and then there's my notorious laziness, which makes me think whether to dig or not. If someone woke me up in the middle of the night, put headphones on my head and yelled "iron or paint", I'd probably be wrong most of the time. Well, that may be the main reason why I felt more confident in the accuracy of the smallest color distinction with the existing F75 LTD than with the new V2.0. It's probably understandable though, because the pitch adjustment, even in DISCRIM mode, makes the tone not quite the same as what I'm used to with my LTD. I think that the new version of the detector Fisher F75 V2.0 a F75 Ltd V2.0 is really good and will be welcomed by all detectorists who, despite their proverbial modesty, always need only the best.
