blisstool ltc64x v2i

[MLR]

In this instance - the most appropriate comment ( from one russian forum ) what i ever read:
Дружище, не будем мешать "Blisstool" общаться с "Blisstool" и делать тесты с "Blisstool" для "Blisstool".

[holyuser]

I currently hold my real argument in my hands, it is my Blisstool ltc64x v3, I just prepare it for my trip tomorrow

Do not forget to pick up at your trip a handful of rusty nails, because without them your garbage blistool not to find any target.

[Qiaozhi]

can they replicate the horse shoe discriminated at 16 inches and the shilling good signal at 15 inches ?

Can you post a link to the video which shows the Blisstool rejecting a horseshoe at 16", but accepting a shilling at 15"?

[enrique81]

Guys chill out.

Kamdox since you own blisstool,tomorrow during your "trip",will you do this :

P.S. If you wish to prove your machine, then do the following:-

Dig the hole to 13 inches.

Place your nails in the hole.

Video yourself setting the disc levels such, that there is no response when sweeping the hole.

Show us the disc settings, and all gain settings.

NOW place coin in situ with nails.

Re-sweep and convince us sceptics.

Please sweep at a rate relative to human usage, and not robots.

All we'll be happy to see such a video

here is the horseshoe at 16 inches and shillling at 15 inches

no doubt the doubters will think up more excuses but they never post a head to head comparison to back up their claims

There are not skeptics those that avoid real testing, or you lost memory (read posts of this topic again).

At the end in one of real tests your Blisstool ltc64 can not detect roman dupondius at 18cm. In inches: it cannot detect roman dupondius at 7".

Mean Blisstool ltc64 cannot detect even a half of your claim of deetcting depth.

What you prove with those horseshoe video, there was a strange signals everywhere?

Thanks for posting the link to the video.
Although this sort of test is very interesting from a demo point of view, it is immediately obvious that the detector is set well into a region of instability. At the very start of the video you can hear a tremendous amount of background chatter. To be honest, attempting to use any detector with the sensitivity set too high, will render it unusable for anything other than a demo. Also, with the discrimination set to reject a horseshoe, you will miss many other valuable items such as roman coins, which will even be rejected at the pulltab setting. Since silver has a high VDI number, this will still be accepted, as shown in the video. That's ok, of course. if you're only looking for silver coins and other higher conductivity items. But (IMHO) the sensitivity would need to be reduced somewhat, otherwise the constant background chatter will drive you mad, and it will be difficult to identify a real target amongst the background noise.

I appreciate that the distributor is attempting to show the Blisstool in the best possible light, and there doesn't appear to be any deliberate "trickery" as such. But anyone watching these videos needs to be aware that there can be a big difference between a demo and actually using the machine yourself. With the sensitivity / gain reduced to a usable [sensible] level, I suspect the depths will be more realistic, as shown in a chart someone posted earlier.

Let's see a video of the Blisstool being used in an iron-infested / trashy area, without deliberately buried coins.

[Skippy]

I'm not sure a real-world test on an iron-infested site is really going to show the Blisstools 'best' qualities. It appears to be more suited to pasture/woodland, where targets are more isolated and deep. That would be a more interesting test.
In heavy iron, most machines will struggle to find anything deep, even if they have modern fast-recovery circuits, eg. Deus/T2/F75.

[WM6]

A little comment on this:

http://youtu.be/iXjy0moYhqE

This test is quite convincing regarding regarding possible trickery accessories used in it. I cannot saw such aid attempt in it. From this point OK.

Regretfully test is not so convincing in his essence: in approval that bliss can detect buried target in real and not only his ground instability response.

What we can see is this:

- detector gave to tester signal not only over target, but away from target too (even on free moving in air) ,
- coil speeds over target and over horseshoe are not the same, why (?),
- no parallel demo test over solid soil around testing location at the same speed was performed before and after testing target points.

Why I remark those points? I have at least one such detector (Bulgarian REX Delta 6, and Turkish Atlantis Imperator II) extremely deep in air detectors (deeper than any other factory detector I tested), but practically unusable in field, because of constant false signals tuned on normal sensitivity/GEB. Tuned to eliminate false signal out, those devices lost all his extra air depth and fall to cheap Chinese models depth.

So parallel test on field stability is of most importance (inclusive normal coil speed movement).

@ Qiaozhi
Thx for your fair and really realistic words.

> I'd like to know how to do a depth test to an accuracy of 2 decimal places

Because it was measured in cm and converted to inches.

The level of amplification has to do with personal skill
and enough reserve to go for the absolutly limits.

As the creator of the detector you will have that skill and as long as
the user can set the sensitivity to it's favorite range no problem.

But the question is where this high sensitivity settings are really
working and how long does it takes to get the same skills in
filtering out by own ear the "peaks of noise" from backgroundnoise.

Well, for extremly depth personally I will accept some higher
level of background noise. The silencer creates a stronger
contrast factor so the weaker signals get filtered out.

> a real live user
OK, seems we have now such LTC64x v3 user and if the
differences to the pure LTC64 version is not big of course
I can find out if the results are the same.

btw. I can give you an overview how the Blisstool
compares to the Garrett GTI 1500 which got an extremly
bad resulat at the german metaldetectortest page.

I prefer the moded GTI because of it's new lightweight design
including special 45cm coil but only if there is no mineralized
soil and no power-lines. Otherwise the GTI starts to beep
like a running wild keyboard.
And the GTI1500 has no manual GroundBalance and doesn't
detect cavity and mineralized stuff like some meteorites.

The GTI can work completly silent but the problem is:
it has to do this without exception.

So you have to set this detector somehow below the
best sensitivity range because otherwise each little
single error signal could be a possible find!
Or you have to research every 5 seconds the new area
because of wrong beeps which is the same frustrating.
(for shure exclude that it wasn't a real target)

However it's fine to listen to mp3-player while hunting
with the GTI 1500 because you can set the beep real loud
and usual the detector remains completly silent.

But the Blisstool is a real good tool to search for small
areas containing little stuff like coins and rings.

I've dug already pistol-bullets 1cm at 15cm depth
very close to high-voltage lines but the ears have to
do a real good second detection job.

The GTI 1500 with 45cm Excelerator Coil would not
have been able to detect those because the sensitivity
must be reduced to around 35-40% (of 100%) which
means almost 3/5 of losing depth at such sites.

In total last year I've been hunting ca. 15 days with
the Blisstool. Search at most highest possible sensitivity
including some and sometimes alot background-noise
was no problem for me, but this can change from person
to person, also depending on it's ambition and skills.

Especially headphone-users will be not amused.

But I'm shure the relative low price for the Blisstool will
motivate alot to "accept" the noise-drawback instead
of paying 1000-2000 bucks more for the same depth.

Before I forget about it:
Discriminating a horseshoe at such depth shown in the video
is no problem, but if the horseshoe is located at 10cm including
nearby coin it looks much worse.

Iron discrimination is not a fixed value. The larger the object,
the less discrimination is possible, especially ballshaped steel.

But the Blisstool has a very fast recovery speed in combination
with a relative small coil so for shure it's very useful at
iron-junk-infested sites - especially because of the special
"Discrimination Depth" poti which rejects surface trash.


btw. I have to do this test again, but as far as I know from
my last years test the Blisstool was not able to look through
high mineralized brick stones at my special indoor testfield.
While the Jeohunter was able to pick up an rusty axe-head
even 40cm below alot of bricks.

I will find out how thick the heavy mineralized layer can
be until the Blisstool refuses to detect or detects the
brickstones only (this MD detects mineralized stones).
And as far as I know the Garrett Ace250 and the GTI1500
also couldn't penetrate my testfield hotrocks.





@ enrique81
thx for the new comparision-charts and the
actual link to this test page.
also interesting that the LTC64v2 could not find
- coin dupondius (1.06'' @ 7.79'' - 2.7cm @ 18cm)
- denarius (0.63'' @ 5.51'' - 1,6cm @ 14cm)
while the formerly Blisstool LTC48 could do it.

Very interesting is the comparision with Minelab -
take a look at those expensive Multi Frequency PI machines and
how those compare...


@ target
Thx for the well made youtube clips.


@ kamdox
Thx for your contribution here.
Perhaps you know details about the depth improvements
of the LTC64x v3 compared with the LTC64 and by the way
you could bury some coins etc. and tell us the results. thx.

Below the old Blisstool LTC64 depth info from their homepage, January 2011:

[target]

the 'silver' coin in the video may not be sterling silver ,but it looks like a later shilling with only partly silver content and some base metal.

[holyuser]

Below the old Blisstool LTC64 depth info from their homepage, January 2011:

The content of that table is an shameless fabrication.
That distances of detection could be reached in the open space, not in real earth soil.
In the real conditions, the blistool metaldetector is impotent to detect roman denarius at 14 cm depth, what we can see here: http://www.geotech1.com/forums/showp...4&postcount=68

[Funfinder]

very well now it seems we have no more other problems
than wrong depth values.

Well, he has used some "experimental model" - perhaps the
newest and for test purposes special modified Blisstool model
(pitched voltage, high stable electronical parts etc.) but at least
now with the depth improved v3 those values haven't changed:

http://blisstool.com/index.php?optio...mid=96&lang=en


But of course there should be still huge difference if we compare
this with our german test-results:

10mm: scripulum / lead ball: depth: 9cm / 14cm
blisstool page experimental model (thin) coin 10mm: depth 22cm

18mm: bronze ring / coin follis: depth each 14cm
blisstool page experimental model coin 18.5mm: depth 35cm

25 / 27mm á 10 grams: coin as / coin dupondius: depth 19-18cm
blisstool page experimental model (thin) coin 24.5mm: depth 40cm

So at the Blisstool Page we have almost the double amount of
depth which would be completly inacceptable if there are no
special factors we also have to calculate.

Personal test 1 Euro (23mm):
within close living-room electricity @ air:
threshold 0: 18cm
threshold 3: 22cm
threshold 5: 27cm

However under good conditions outside threshold 8-9 is no problem and could result @ 33-36cm (not tested yet)

Depending on the soil, close distance coil to ground and no electricity lines nearby this may result in 25-30cm for a buried 1 Euro coin for trained ears and 20-25cm in almost silent (for Blisstool-Newbies or real relaxing) mode.

Those are just my personal results and if the LTC64 v3
has a real good depth improvement 1 Euro may be found buried at 35cm which would be just 5cm less than with those posted experimental detector tests 24.5mm @ 40cm.

The 1,5mm is not much difference - in this range 1mm of larger
diameter gives 1cm more depth.

So if the posted results at the blisstool tests are in air tests -
that's the big question - there even wouldn't be much difference
to my ("old") model!

We have to find out about this because depending on the
mineralization the Blisstool (and almost any MDs) loses depth.
As we also can see at the german test site.

That "before the test a 7cm iron nail gets discriminated"
desribed in german here:
http://www.metalldetektortest.de/detektortests.html
for shure also reduces some depth but exactly how?
Where's this nail located exactly, permanent or not?

Neverthless those middle long time ago buried items
(also written there) would improve detection depth.

Those are the special factors including the level of mineralization
plus including the distance of coil to ground we all have to know.


@ target
thx for the additional info, perhaps you can show us the
LTC64 v3 depth difference air vs buried, using 3 different
sized coins including described soil mineralisation level.

Okay, one more time ... I will try to translate it literally...

------------------
All of the objects are buried years ago next to iron so it resembles reality, because tests in clear soil always have greater depths.

Before the test a large 7 cm. long nail is discriminated.

These tests should not be used when buying a detector because in other types of soil values will be different.
-----------------

It does not say what kind of iron is buried next to an object.

Do not forget to pick up at your trip a handful of rusty nails, because without them your garbage blistool not to find any target.

My trip went well, as usual, always, but your humor shows your ignorance considering the fact that Blisstool ltc64x v3 has perfect discrimination of iron. Anyone who has used this machine knows that.
