2. Multi 3 (M3) has been added to PARK and FIELD modes.
This mode is more heavily weighted towards the low frequency response of the Legend (4 and 10 kHz) It’s Ideal for humid, wet and/or conductive soils.
It eliminates the moisture in the soils which can cause falses. It also weakens the response of targets generating 10-11 IDs such as coke and aluminum foil.
(This upgrade has great potential for detecting in any environment where there are a lot of low conductors that cause threshold noise and “part” signals. The conditions described above under “Signal Balancing the Legend in a Tough Target Environment” above would be an example). The downside here though is that because the ground forms part of the signal, when you reduce a detector’s sensitivity to the “join” between ground, iron and non-ferrous targets, low conductors also drop out. Steel targets area good example of this. When you are finding these “fence-sitter” type objects you are best able to hear small gold–especially the less solid objects such as bracelets, chains and earrings.
Overall the added stability that the M3 mode gives is surprising–as many corroded or “part iron” objects are ignored–even some bottlecaps. Making these kinds of objects “inhibit” (drop out) with repeated coil passes is also easier. M3 makes the Nokta Legend’s response more like the M1 (or MW) modes. As in the example above, if you are frustrated by small, part-ferrous types of targets (caps, hairpins…), M3 is the way to go. Be sure to use the coil to get the most from this mode’s foil and corroded target rejection. (See Basic Skills and the Legend,” pg 32).
