You will end up finding that the threshold in the Gold mode on the Legend is the only beneficial threshold that the Legend utilizes, this is of course just my opinion
the threshold in park, field, and beach mode is totally different from the threshold in gold mode
the threshold in park,field and beach mode is a reference threshold, and the threshold in Gold Mode is a true threshold or live threshold and trust me there is a difference between the two thresholds being utilized in the Legend
if you are one like myself whom detects in all metal the threshold in park,field and beach modes is pretty much a mute point what the reference threshold does in those three modes is to alert you when you have swung over a target that you have notched out, so if you detect in all metal the threshold in park,field and beach mode is pretty much useless
the threshold in Gold mode is what most of us are accustomed to, and the gold mode is a threshold based mode, just like your Xterra was in gold mode
I also owned and still do the Xterra 705 which it took a good bit of patience to learn the Xterra 705s language, it took me almost two years for the light bulb to finally turn on when I was learning the Xterra 705 but when the Lights finally turned on the Xterra 705 became my favorite detector to use, the Xterra 705 was one of the most under rated detectors to have ever been produced and I still feel it is one of the most under rated detectors to have ever been produced still to this very day, I still use my Xterra 705 occasionally and it is one detector I will never part with because of its capabilities
the Legend can be as easy to learn and use as you want it to be, or as difficult to learn and use as you make it, with the factory default settings the Legend is pretty much a turn on and detect detector, and if Nokta ever straightens out the latest software version I feel it will be a force to be reckoned with, but not with the current software 1.11 it still has issues, in my opinion, and the reason I state this, is because I tested the 1.10 Beta test versions which were the pre cursor to 1.11 the 1.10 beta test version 3 is what the 1.11 version should have been but just before the 1.11 was released to us I feel something was changed in the final version just before release, if 1.10 Beta Test Version 3 would have been left alone then the Legend would be a fantastic detector, and it still can be a fantastic detector but Nokta is going to have to take a hard look at 1.11 and re adjust everything back to what I seen in 1.10 Beta test Version 3, before I will ever say the legend is fantastic to anyone or a finished product, and I am not the only one that feels this way, there are many many reports from Legend users that will tell you the same things I have just stated, and there are others that will tell you there is nothing wrong with the Legend, just like there are Equinox 600 and 800 users that will never admit that those two detectors had water leakage issues, I just happen to be one that calls things as I see them
