Firstly, I must confess that Georgi at Nexus is a friend of mine. Although I haven't used the final product (as displayed on the Nexus website), I was with Georgi when we did some field testing of the prototype. It's a real beast. We originally did some searching at a river site by the Thames using a 9" OO coil. Georgi found a really strong deep signal and insisted on digging it out, whatever the depth. Eventually we got to the bottom of a waterlogged hole, and it turned out to be a chunk of galvanished roof panelling; which of course is non-ferrous, buried at a depth of 1m. The Ultima coil was able to detect the same target with ease. The prototype was a single-frequency version. According to the website, it can detect a roman helmet at 190cm (6.2 feet) in normal soil conditions. I can quite believe that.

Knowing a bit better you as a person - i know that you are speaking truly and honestly.
So i do take what have you just said as definite truth.
I feel bad because never had chance to try any of Nexus models.
But also i do know that concept with resonant coils can be pretty powerful indeed.
Looking forward to get chance to test anyone of those.

A roman helmet 190 cm deep...?... so no problem finding Carl's silver..... 1KG silver coins ..only 25 inch deep...( not even 70 cm) http://www.geotech1.com/forums/showthread.php?t=11831&highlight=cache

Have you ever made a hole 1,90 meter deep...?

Galvanised roof panelling.. non-ferrous??...at the Thames 1 meter deep ..it must be a lot rusty iron...
If I am not understanding things.. please explain.

Hope we stay friends...

USED and TRIED it but just one time, that thing requires experience and it's a critical setup, but, depending on coil also can give very impressive results, much like a powerful PI than a T-R VLF machine

by myself found a silver coin 29mm diameter dug in a hole 40cm deep with it, but, as said, used just one time so I have no great experience with it and its controls

found also other stuff, like aluminium things and bits and small copper scraps (ancient) at deep from 20 to 35cm

what to say ? if you have the money and are a SERIOUS hobbyst or professional TH go for it, it's worth the effort and expense, but if you're just a simple hobbyst or casual TH my advice is save your money and buy something "middle class" machine less expensive and less troublesome (and less powerful)

toni, who are you? why you are so interesting in Nexus? for the such expensive price you can buy xterra-705 and not ask the forum. nothing fantastic there. good analog schematic and only. one member via my pcb photos had repeated it... i got reply from him...

write more about yourself.

I've had a nexus standard 1 year ..
at the end I sold.
I have now MXT Pro 10x12 SEF, and my results are much better.
when I use my detector, I enjoy.
when a detector has a long learning curve, the results are much worse.
good things have to be simple, is a universal law.
in areas with lots of ceramic (Roman, medieval) the nexus does not work well.
also tend to dig small nails, because the signal is as small coins.
before you buy one, try to test it to see if what you want.

recently tried a nexus ultima, and it is impossible, the coil is so great that passes over three targets at once.
I do not like anything.
for a competition, surely would win, but for day to day, is impossible.
sorry for the language.

The cache test is different to the roman helmet. The coins are seen as separate loosely connected targets, but the helmet is one unit that gives a stronger signal. However, the cache would not be a problem for the Ultima.

With 20" diameter coils" you would not expect this detector to be used for every day searching. If that was your expectation, I'm not surprised you were dissatisfied, if you were comparing it to a general purpose machine like the MXT Pro.
If you want to use a Nexus detector for every day use, you should purchase the 4" coils. Even the 9" coils could be overkill in some areas.

A Roman helmet at 190 cm... ?? well I never found thing that deep...

Yea... I know how hard it is to find 1 kg silvercoins at 70 cm.. if the detector from you friend can find it... then go for it....

Hi Ap,
I have to say that with standard (that I used one time only) is impossible to detect a "Roman helmet at 190 cm", cause the coil is not so large and so it's good for small stuff at medium depth or very large things (meters...) at meters depth (maybe, cause I've never dug airplanes from the ground)

but I think that Ultima design is a different thing, as Qiaozhi said the coils are very large and not for "casual" use... like coin hunting: with that coils and a critical setup is possible find stuff at meters underground much like two-boxes do, just in that case it's a VLF with coplanar coils and critical nulling, but the net effect is like having a big PI coil (1mx1m or so) and PI detector that can find large stuff underground about easy

then, we have also to say that dimensions of the elmet are NOT specified: some are very large like this one... so I think is truly possible in the 2 meters range detecting them

Hello Max,

Good to have you back on planet Earth...

Nice helmet.......

The Roman helmet used in the test was 9" external diameter. It does not have the extra parts, face plate and other additions.

If you don't like Nexus, then why is your avatar showing a Nexus control box?

Georgi tells me that he once issued a challenge for anyone to try and beat the Nexus in a real test in the field. Apparently the challenge still stands. You can contact Nexus for details.
