Surprised at the 7 µsec smoothness in wet salt sand and in the seawater?

the proto are not waterproof
the coil alone, under water is very stable

I think the 7us will be exploitable underwater
by lowering the sensitivity
lowered the power and keep a delay at the lowest
will always give a better sensitivity on gold

you really have to see it to believe it
all those who I did a demonstration on the beach
Nearly 100 prospectors on a rally (beach)
all have the same word: incredible :)

Well that's good enough for me then....:smile:

Absolutely, an electronics improvement.

All kinds of detectors do that. My Cuda does 20" +, DF, TDI Pro the same.

Carl, when might we expect to receive more information?
Maybe next year.
I'm really looking for a PI with iron discrimination capabilities.:detecting:

The US 5 cent piece "nickel" is a pretty good standard. Rings are hopeless - no two are alike.

???????????????????????????????


Rick, you have hit the nail on the head. STANDARD TARGET.

This thread isn't worth a carrot, unless it's contributors relate to a standard for the target, coil-size, and power of the TX pulse.

There are several other factors as you well know.......PRF, Coil diameter, the actual machine and its setting, and the absolute status of the search-location.

So all comments must be accepted with their individual compliance to those basic requirements......a very demanding standard, but anything less means the contribution is subjective.......matt

Hi,

what type of targets do you use
I test in this moment the last prototype Fisher / manta

I have never had a more stable PI
at 7us I can lower the SAT to less than 10% on wet sand
the more compact it is, the smoother the signal

18 inches = 45 cm // is possible, everything depends on the target and the metal
with the old version, I had obtained big rings 18k 15/20 gr
at about 40cm = 15.5 inches

we would need one or more targets
that everyone can find, anywhere in the world
low conductor, of course
someone has an idea for the target


When might we expect to see some information on the Manta. All has gotten very quite about this machine after the youtube demonstration. But I'm interested.......

Hi,

it's not really a manta anymore
now a Fischer :blowup:

the devellopement team is working, now on the mechanical part
the box and the rest ....
the coill takes a lot of work, nobody has ever produced a coil
'' in large series '' able to start at 7us and can be less
you have to wait for the first tests of the final version

meanwhile, my last outing, a woman's bracelet
light, 4.2 gr 18 K
obtained in a compact and wet black sand, about 20/25 cm
a very light sound, 6.5 us !!!!!!!!!!
with a very slow sweep, gold digger mode

I do not know, if he saw the clasp 18k too
or one of the rings, since theoretically
on a bracelet or a chain the detector sees only a piece

on this specific case, I think there are only three detectors capable of taking this target
and not sure that the other two would have had

Many will be blown away by the performance of this machine
we get a sensitivity on gold that I have never seen
but again, we have to wait ...

I use detectors calibrate to less than 8 us
for several years, the modified 5c and the different version of Alexandre manta
if you have never used, a detector working at 7us and less
you have trouble visualizing what difference can make

I assure you, she is huge ...........:wink:

Thank you Le Jag for this update on the new Fisher PI. I am anxiously awaiting the release of this detector and will be purchasing one as soon as it is released.
Also, thank you for your contribution to the advancement of PI technology. It is long overdue.

Hi,

Do you know when this fantastic Fisher Manta detector will be for sale & price?

Development programs, including long lead time mechanical parts always take longer than is impatient enthusiasts wish that they would.

The new Fisher PI will appear. When that will happen, what it will be called and what it will cost are things which even First Texas’ Management probably don’t know for sure at this point.

Wat does seem reasonably clear is that the design offers performance never before demonstrated in a beach/underwater detector. The smooth operation in moving salt water at very short pulse delays means that it will find a whole category of targets not detectable in salt water by ANY detector on the market - small low conductors like gold chains, charms, earrings, and especially white gold items even of larger size. Add to that a useful level of iron discrimination and a real breakthrough will occur.
