The Quest company is also working on a new series of advanced metal detecting machines, also in the beginner-middle level, but with a bunch of cool features.

With Minelab's simultaneous multi-frequency it's like using all your coils in one sweep of your machine. Three Simultaneous Frequencies The Vanquish 540 has 25 discrimination levels compared to the 5 levels on the 340 and 12 levels on the 440. Adjustable Iron Bias allows users to switch between High (default) or Low, meaning the detector will find more treasure and less trash. This model weighs just slightly more than the 340 and 440, at 2.9 pounds.

Second Hand Metal Detectors – The Pros & Cons

The design of the Vanquish series is rather curious, and while it really reminds a device from some kind of videogame of the 80s, at least it does not fall apart when handled (like Go-Find does). Vanquish looks pretty solid.

Having to revert to using basic metal-detecting techniques is another charm that you might find oddly endearing about the 340. Low frequencies are more responsive to metals that are high conductors while higher frequencies are more responsive to lower conductors. So, the lowest frequency is best for large silver pieces, while the highest frequency is best for small pieces of gold. Another advantage to Multi-IQ is that hunted out areas are given new life. While a single frequency metal detector can search an area with one frequency, the Vanquish line using Multi-IQ searches an area at multiple frequencies. So, if an area did not produce any gold, the Vanquish line may find that left behind treasure because of its higher frequencies.It has several advantages over the Vanquish 340, and a price comparable to the Vanquish 440. For a beginning metal detectorist, or if budget is an issue, I would highly recommend the Vanquish 340. Minelab is a great company offering quality products, so you will not be disappointed using one of their metal detectors! If you are looking for a new detector or upgrading from a single frequency detector that is a breeze to use yet very powerful, the Vanquish series is absolutely for you!
