The depth at which the Nexus metal detectors will be capable to detect various in shape, size and weight targets will depend on different conditions as it is with all other metal detectors. However complicated the answer to this questions might be we can still provide you with some basic information of what the Nexus can do in this regard.
EXAMPLES: Roman sesterti, Victorian penny (size 30mm average) or any other coin with this size, buried 14"(36 cm) under compact undisturbed normal soil is easy to detect at minimum Gain (sensitivity) setting with the 9" search coil. A Hoard of coins (1 kg.) buried at 24" depth in normal compact and undisturbed soil is easy to find with the 20" Nexus Ultima search coil.

This shape was chosen for one reason only: EFFICIENCY. After years of experimentation we came to a practical conclusion also well confirmed by the laws of physics that there can be no more efficient search coil assembly than one made out of circular loops. The result of overlapping two circular loops was the figure of 8 shape.

A search coil tuned in full resonance will be in average 100 times more sensitive compared with one not tuned at all. For this reason the Nexus search coils are tuned in full resonance within 99% tolerance. The imperfections of search coils not tuned in resonance are not possible to compansate by any electronic circuit.

Search coils with various sizes and frequency settings other than the mentioned in the products pages can be made only by customers order and at additional cost subject to separate agreement.

The Nexus metal detectors are fully capable to find targets of any size and composition. Nexus can detect any size coins at depth greater than any other known detector has achieved so far.

After full advanced payment has been made the ordered unit(s) can be supplied in period from 1 to 6 weeks, subject to materials availability and customers order waiting list.

Yes they can. The beach settings are explained in the online User Manual for each model.

All Nexus detectors are suitable for hunting gold nuggets if they are equiped with search coil from the Gold range (SE Gold, Ultima Gold, Coronado Gold).

The most dificult conditions for work with any metal detector is considered the black sands in the USA. To our knowlege Nexus are the only existing metal detectors capable to work on those balck sand, which will suggest that they will work in almost any severe mineral conditions arround the world.

At this stage we do not offer rechargers or rechargeble batteries.
