Old VLF'r wants to know....

Guest
I have been using a VLF machine for about 35 years now to do the beaches here in New England. I currently use a DFX. I am curious about PI machines and what to expect when changing over.
VLF machines descriminate and from what I gather PI machines do not. VLF machines have an "all metal mode" which I use exculsivly for the beach. In "all metal mode" I can tell "faily well" what is junk and what is not.
 
I have been using a VLF machine for about 35 years now to do the beaches here in New England. I currently use a DFX. I am curious about PI machines and what to expect if I change over or just add to my detector ownership.
VLF machines discriminate and from what I gather PI machines do not. VLF machines have an "all metal mode" which I use exclusively for the beach. In "all metal mode" I can tell "pretty well" what is junk and what is not.
Does a PI machine, with some practice, allow the operator to discriminate good from junk just by the sound? Or is the sound constant regardless of metal detected?
If anyone has made the transition from VLF to PI I would like to hear about any issues they might have had.
At Surfscanners web site it is stated that the Aquasearch is a waterproofed Goldquest, but the pictures do not show that. It shows a completely different board layout. The Aquasearch has 3 knobs not 4 like the Goldquest and has no toggle switch.
Is this correct?

Most PI users operate both VLF, and PI units. One doesn’t necessary replace the other.
I’m not certain what you mean by Junk. If junk is iron, with practice one can tell most iron from other targets. If you are referring to pull tabs, and foil, why would you want to eliminate them as that’s where the gold jewelry lays. If you discriminate out tabs, foil, and such, so goes your gold jewelry.
The Aquasearch is a Goldquest in a waterproof case, and if you go back and look at the photo’s again you will see 4 knobs, 3 on one side of the case, 1 on the other side.

If the switch is unavailable on the Aquasearch, then the Aquasearch does not offer the same ground filtering performance as the Goldquest, would that be a correct statement.
It's the statement that the "Aquaquest is a waterproof version of the Goldquest" I find confusing as I would expect the electronics and controls to be identical.
Regarding foil... most seasonsed VLF'rs can spot Alum foil due to it's unique broken sound in a one direction swing. It's not that I discriminate Alum foil electronically, I discriminate Alum. foil with the sound it makes. Iron of course has it's own trade mark signal in all metal mode. Pop tops and such sound like good targets to my ears, but alum foil does sound a bit different to my ears
Maybe my question should be rephrased... Do PI machines make sounds similar to a VLF machine operating in all metal mode?

<STRONG>I should have mentioned the switch, I guess it was to early in the morning. If you would like to see a switch, look at the end view with the headphone pigtail. It’s not too distinguishable because the switch has a black boot over it.</STRONG>

<STRONG>Let’s put it this way, I find it hard to believe your confused over this. I’m going to take this that your serious and not trying to be sarcastic. The controls are the same, 4 pot’s, 1 switch on each. Same circuit board. All of Eric’s detector’s are individual custom made. They are not run off a production line. They are hand built by Eric himself. If you have a special request, with a little notice, it may be able to do.</STRONG>

<STRONG>This is too much of a blanket question to make an answer to cover all PI detector’s. With the Goldquest, and the Aquasearch they are differences in the audio that is unlike the all metal mode of a VLF.
For more detailed information, please phone me at my shop.

Truely I am not.
The Aquaqest has (3) knobs on one side, (1) knob on the other side and a switch on one end.
The Goldqest has two knobs on one side, two on the other side with a toggle switch between them.
The outside layout of the controls are in different positions, hence the reason for my qestioning when the term exact is being used.
