I have the Vanquish 340 since I already have a Nox 600. I wanted something I could leave at my 90 year old parent's house 1500 miles away so I wouldn't have to pack a detector or leave one there that had internal rechargeable batteries (like a Deus Lite or Nox 600) that need refreshing. No way are my parents going to be able to handle that task!!!!. I have nieces and nephews that like to hunt with me too, so they will have an easy to use, light weight and really adjustable detector that actually works very well for what it is.
I really like the 340 so far. It really does seem to be a totally entry level Equinox. It sounds and acts very much like the Equinox, the controls are similar and even with the 10"x7" V10 coil it will easily hit and correctly identify 8" low and high conductor US coins in all three search modes thanks to Multi IQ simultaneous multi frequencies I guess. I really like the build quality and the nice adjustable shafts that will fit just about anybody. The 340 only has 3 tones so I have to look at the screen more often. It is my understanding that all three search modes use the same recovery speed and iron bias which cannot be adjusted. That has been my experience so far. It will give medium and high tones on crown bottle caps which are broken up and null a lot so the iron bias setting must be pretty high. That does make the 340 which does not have the high/low iron bias switch, pretty slow to recover in thick iron. On the great side, it can hit targets AND identify them in my test bed that only the Equinox has been able to hit and identify and I have tested lots of very famous mid level detectors on these targets. Most will hit them, none can identify them. It will also hit extremely small low and high conductor targets too easily like micro gold jewelry and even hit a 2/10 gram gold nugget at 3" in my test bed!!!
So, the 340 is an excellent entry level detector. I would happily use it in tot lots, bark playgrounds, open fields and parks with low trash levels, soccer, football and baseball fields and even at a fresh or saltwater beach in wet or dry sand.
