Priceworth China-LRLs !

[Funfinder]

Maybe somebody here knows the exact price but I guess those Electroscopes from chinametaldetectors found here:

http://www.chinametaldetectors.com/M...ector/Model20/
http://www.chinametaldetectors.com/M...tector/ModelB/

will cost just around 500 dollars. Electroscope is a good term because those signalize electrostatic.
btw. only the antenna unit seem not be not made out of plastic and those devices have a "self-electrostatic" reset button.

Somebody knows what schematic / homebrew plans we have here in the Forum already are the closest to them?

However - just for trying such kind of devices (if someone can't built them self) for the first times it's much more clever buying some that costs only 500 bucks instead of 5000!

And if even the half of the described range works those are pretty powerful:

Model-B users can search for outdoor B0 ~ 250 feet of the coins in 1000 feet in size and scope of the larger items. Can search more than 9 meters depth of the larger items.

A second question remaining:
Can you order them worldwide and under what conditions (warranty, payment rules, delivery time)?
