Looks like it would make a good cache hunting machine. A bit pricey though, $5,499.95 at metaldetector.com. It will be interesting to see where that technology goes in the future.
There's several from Makro in Turkey. The Jeotech LED System machine does work but I've extreme doubts about the Jeotara Bionic System which is just a long range detector and we all know how successful they have been in the past.
