The Rutus Alter 71 was introduced in 2017 and is still in production. The Alter 71 is a VLF metal detector aimed primarily at coin, jewelry, relic detecting plus gold prospecting. The Nokta/Makro Impact is a "selectable frequency" detector that lets you select one frequency to use from several options. The Alter 71 frequency adjustable between 4.4kHz and 18.4kHz in steps of 0.2kHz. There does not appear to be a Rutus distributor in the U.S. at this time (Dec 2018) but enough of these detectors are finding their way to the U.S. to be listed here. The price as listed in U.S. dollars is approximate depending on exchange rates.

"A metal detector with the capabilities demanded by advanced users, but provided with preloaded settings which make it ideal for beginners also. The Alter 71 detector can not only be used as a static detector for very deep low frequency work, but just as effectively as a rapid, dynamic detector for locating small non-ferrous objects using high frequencies. The flexibility of the detector is enhanced further by the option of dual mode, using the benefits of motion and non-motion mode simultaneously." Source: Rutus website
