........so please give me a hand over here. I recently ordered a Detector Pro Headhunter Pulse. So I am new to pulse and hope the PI crowd will accept me. I am doing quite a bit of research so that I will understand what I'm doing out in the field.On the Headhunter Pulse and I've noticed on other pulse units too..... that there is a frequency switch. For optimum performance it should be set properly. The recommendation is to use a nickel and tune to it. I did read, that by tuning to the nickel, you are setting the detector to be hot on men's medium sized wedding bands/rings. If this is true would it not be better to set the frequency by using a small ladies 14K band ( for example) and tune to it? I'm thinking that the detector would then be more sensitive to the smaller ladies band which often contain diamonds.If this was done would it still hit hard on the larger sized, men's rings?? Thanks for your replies and hopefully, suggestions for setting this control.

It is not a frequency switch, but it's a variable potentiometer. This control is also controlling the pulse delay.

Run the frequency control up at the highest pitch. This will put the detector at 15uS. pulse delay.

Set the threshold as to just hear the threshold. Do this with the coil lowered to hunting position. This will put your detector, ( Headhunter PI ), at the most sensitive, responsive point it can be at for the lower conductive item you are looking for.

Hello Ivan, I've just returned from holidays and noticed your query.

I'm not an 'expert', but that's not too important in this case.

I've not scanned the forums, so my reply may be somewhat redundant in as much as others may have answered you correctly earlier.

The reason for the suggested use of a nickel to 'tune' your' PI (or any other detector), is to define a 'STANDARD' item which is commonly available to most folk, and reasonably represents the broad range of those particular artifacts which you are seeking.

Men's rings or ladies rings, are not standard test items, and even less so if the variable adornment of diamonds is involved within the band of gold.

You can take the male's fattest gold ring and the woman's thinnest ring and take their detectable parameters, and realise the variations.

The basic rule is to set up your unit to detect the most difficult item of interest, then the rest should be relatively easier to find.(All other things being equal.)

Alternatively, on a personal level, if you set up your unit to detect a child's simply designed small gold ring, then all other gold rings should be that much easier to detect.

So Ivan, the important thing about any suggested test item is, that it must be a standard representative item, and commonly available to all.

Hope that makes sense.................All the best..............MattR.UK.

That in some environments you may not be able to run at the highest frequency. I had the HH PI ( great unit ) but the beachs I mostly hunt, there is tons of iron. But, even without the iron, some beaches I could not run the PI at it's highest frequency because it was a little unstable.

So, the HH PI can be tuned not only to hear the smallest gold rings, but also tuned to make it as stable as possible for the best hunting.
