Detexperts, Coil Height & General Operation Of Nexus

I feel compelled to write a new blog on this subject even though I've focused on it in previous posts, the main subject will be about coil height. Since a well known YouTube channel has started posting videos of the Nexus Standard MP V3 there's rather a lot of confusion amongst the herd in regards to certain areas of its operation. A few videos have cropped up trying to correct said "YouTubers" apparent 'misinformation' on the subject of correct operation of a metal detector. I use the word 'metal detector', because Nexus isn't operated like any other detector on the market and I've mentioned this point literally hundreds of times now, however it would appear that many just don't have the ability to take on board such information.

So lets get this out the way first, "Detexpert" has to be one of the most stupid fucking things I've ever heard in my life, but it would appear that some people who have this title look upon themselves as supreme beings with mountains upon mountains of unbelievable knowledge when it comes to moving digits up and down on a screen. Me personally, I feel so privileged to have some dick head in a "Detexpert" t-shirt telling me about all the painfully obvious elements on the running of a 'turn on and go' metal detector. 

Now lets get one thing straight, if you've never used Nexus and you're comparing the operation to, say, your Manticore, it's like comparing chalk and cheese. The operation of the Manticore, Deus 2 etc is in no way the same as operating the MP V2 & MP V3. Now I understand, being a Detexpert means that you know everything there is to know about metal detectors, but, I hate to break it to you, you know nothing about Nexus, I know that might be hard to process but it is, in fact, the truth.

Modern metal detectors are made in such a way that you can scrub your coil on the ground, doing this will have no real detriment to the machines operation. Why Is This? it's quite simple, these machines have filters on them for easy operation, these filters will make operation less troublesome but they will also effect performance. That's why modern tech units have pretty much reached their limit in regards to depth and discrimination at depth .... or lack of.

So let us turn our focus to coil height, people are saying that it's wrong to be swinging your coil 3 or so inches off the ground because you'll be missing the deeper targets. I can in fact say, that when swinging digital machines you will be missing the deeper targets, to squeeze the most depth out of them, you have to stay low. The opposite is required when running Nexus machines, the unit will go deeper swinging the coil 2 to 3 inches above the ground as opposed to scrubbing it on the dirt. 

Below Is A Video Demonstrating What I've Explained In The Above Paragraph

How Do You Know What Height To Swing The Coil?

The answer to the question above is easy, when you ground balance you swing your coil at the height the ground phase kicks in. This will vary depending on both the size and the frequency of the coil that you're using. That's the beauty of Nexus, once you grasp the language, they tell you everything you need to know on an 'audible' level. Due to the detectors having no filters to inhibit performance, you have to use the machine in a way that compensates for this. At first it can all seem counter intuitive but over time you'll come to feel comfortable.

When performing the ground balance procedure what you're doing is tuning the detector in such a way that the threshold resonance becomes as stable as possible - What Do I Mean By This? when raising and lowering the coil you want the least deviation in the threshold tone. Once this has been achieved you then run the unit with an audible threshold, to eliminate further ground noise you swing the coil at the height you ground balanced the unit at. Having set the machine up in the way explained it will give you the best chance at hearing really deep targets because the deviation of the threshold isn't being effected by the ground, it will only rise when a metal object is swung over. 

Swinging the coil too close to the ground will result in too much ground interference thus inhibiting the ability to, not only hear the deeper signals but actually pick them up in the first place. Once again I'll say that it will feel counterintuitive at first but once you get your head around it you'll be surprised how smooth the operation is.
