In my opinion, the DI99 program in the Nokta Impact detector is the fastest and the best to perform the recovery speed test. Usually I don’t use polyphony while hunting with any machine. But the polyphonic tones on the Nokta Impact are easy to perceive.
In addition: all programs in the Nokta Impact are able to separate close together targets somehow. Even Deep and GEN. The latter was a surprise: it works like a static mode but nevertheless tries to separate something.
All about the Nokta Impact metal detector is collected here (news, different tests and comparisons, reviews and opinions). On Knowledgebase pages there is also additional info on this machine (user manual, the list of coils, specs, features and much more you should know about this detector).
