anyone who uses them, I would like some feedback on the vanquest, detectors
They are the Vanquish series, and what would you like to know? I have the 540 Pro Pack (meaning 2 coils and wireless headphones) and I have found it to work well. I keep the 5X8 DD mounted full-time for the majority of locations I would grab it. Now, what would you like to learn? Are you trying to compare it with any particular make or model detectors? What types of applications would you use one for?jimmy clark: said:anyone who uses them, I would like some feedback on the vanquest, detectors
The only drawback of the Vanquish series which both Monte and I have repeatedly pointed out is that since they are simultaneous multi frequency detectors, Minelab in all their wisdom, did not include a way to manually ground balance them. In really hot mineralized dirt, they will not auto ground balance. So, the hot ground becomes an audible target in the lowest iron range which makes all targets sound like they have iron around them. There is an easy work around but ......... that should not be necessary. Not adding a way to ground balance these excellent detectors is just plain dumb.
Otherwise, on mild to moderately mineralized ground that is not absolutely a carpet of man-made iron or aluminum trash, I would pick a Vanquish without hesitation for a fun, no nonsense, get the job done detector. Are they as good as an Equinox.......NO.
I wonder if they could ad a gb on the 540 through a update?

oh I see what your saying. you could use the same button for ground balance as for pinpointing if they wonted to ad that feature. they should ad that feature on an update.
the vanquish must have fixed not auto gb. if theres no button to push like ground grab or like my dfx which they do call auto gb, then its fixed. set at the company.
The Vanquish do have a fixed or preset GB. It is not impossible for a SMF detector to be designed that way. The problem with them is that it is different between the Coin & Jewelry modes than the Relic mode, and it is especially noticeable in a more mineralized ground environment when you compare the first two modes with the third and activating the "All Metal" push button.jimmy clark: said:the vanquish must have fixed not auto gb. if theres no button to push like ground grab or like my dfx which they do call auto gb, then its fixed. set at the company.

The Vanquish models do not have a true, Threshold-based All Metal mode, and activating that switch simply puts it into an All Metal ACCEPT Discriminate mode by accepting all of the Disc. notch segments. That is similar to the Garrett Apex in 'ZERO' mode, referring to Zero Discrimination, thus accepting all ferrous and non-ferrous metals. Many other makes and models provide a similar Zero-Disc. setting whereby they can accept both ferrous and non-ferrous targets.
With the Vanquish series, and I own and use the V-540 Pro Pack unit and have both coils, I was quickly able to determine the 'fixed GB' behavior in the first ten or fifteen minutes of checking the detector out. Once selecting a mode you can activate the 'All Metal' function and bob the search coil from about 6" to about ½"-1" and back up several times. You will note the difference in audio behavior between the Coin or Jewelry modes and the Relic mode.
In some modes you will hear an audio 'beep' or 'audio response' as the search coil approaches the mineralized ground, and this is the behavior of a too-positive GB setting. Yet in a different mode you hear an audio report when the search coil is lifted away from the ground, which is the behavior of having a too negative GB setting.
During a search of a site, using the All Metal activated zero-Disc. function can cause a lot of false signals, and that was what happened to me when I first started hunting with my V-540 and checked out the different search modes. I was searching an old-use site that has mineralized dirt, but it had dips and depressions as well as humps or rises in the surface texture to sweep over.
Depending upon the mode used, with 'All Metal' activated, you would hear a false 'beep' or audio response from sweeping over a depression or void in a mode with a too-negative GB function, or when sweeping over a small mound or elevated soil when the coil came closer when in a more positive GB designed mode.
I don't care for all the false signals, and I live in and hunt in very mineralized ground conditions so it is more notable than if hunting in mild or mellow ground. Therefore, i do not use the 'All Metal' function at all. I search in the 'Custom' mode and I accept ALL of the Disc. segments except the first two. That way I hear most ferrous and non-ferrous targets, but do not experience the false responses caused by the fixed GB assigned to the particular mode I based the Custom program on.
The Noise Cancel function has nothing to do with the GB behavior of the Vanquish modes. I discussed this early-on with Minelab and verified the Vanquish series rely on a fixed GB design. I wish they had a way to incorporate a manual GB with the Vanquish, but it is what it is.
Monte
And I will respectfully disagree right back for the following reasons:jmaclen: said:Monte, I have to respectfully disagree with you on your use of the terms "fixed" or "preset" ground balance being present on the Vanquish. It does not have a user adjustable ground balance feature. It does have ground balancing happening in the background. Unfortunately for users like you, me and both of the gentlemen that I will quote below, it cannot keep up or automatically adjust enough to handle high mineralization like what we sometimes experience.
