Here’s what I actually wrote about coils for the AQ...
“PI coils are not that hard to make and I suspect that if there is a market for it someone could make aftermarket coils or build their own.”
I said nothing about such coils operating well - much less operating at 7 microseconds pulse delay.
As far as significantly deeper than X,Y and Z, here’s what I observed. I put a nickel on the black sand beach at Coronado San Diego. The AQ hit it at well over a foot. My Nox 600 hit it at about 10” with a normal VDI for a nickel.
I then buried the nickel at about 10”. The Nox couldn’t hear it, the AQ did. Curious, I then buried it at about 7-8” and the NOx got it but with a very low VDI.
Next I buried the nickel about as deep as I cared to dig - about 17 -18” - the Nox, of course, got nothing. The AQ hit the nickel just fine with a solid tone.
So now you want to play semantics??? Really? A thread about one certain machine, and now it is about building coils on any PI???
Compared to a NOX??? Boy that must have been quite the test... A VLF that does have issues with mineralizaion against a pulse a high powered pulse no less. You still did not answer this...
This is what I am talking about from the post above... "The minimum pulse delay setting runs fine in almost all cases. Carl Moreland - the chief Engineer at Fisher posted a while back that he ran it at under 7 microseconds delay in running salt water at an Oregon beach - likely with significant mineralization.
I had my “mitts” on one before Christmas for a couple of days. I ran it on this beach in San Diego with the minimum pulse delay and the stripes of black sand were a noise problem, so I increased the PD about half way and the problem went away.
Hey Sandcrab, No need for all the “he-ing”, it’s me you are referring to - Rick Kempf - I use my right name - it’s on my signature line at the end of every post.
I’m not sure what it is that bothers you about my interest and hard effort to report to the forums everything I can find about the project, but perhaps you ought to just relax and enjoy the ride.
Ok, lets start with answering the highlighted post above. Since you chose not to answer it, I will ask directly. How can this machine run a delay at 7ms in running sea water with significant mineralization, but you had to bump the delay to half in what looked like damp sand, no moving sea water, in fact no water at all, with a few streaks of mineralizaion in San Diego?
How can it handle a heavily mineralized beach, or as some put it, really bad ground?
Now the second one is pretty easy too... I quoted directly from you.
When LE.Jag states that various other machines would have gotten variously smaller numbers of the targets he recovered in the same situation, he is basing that on years of using Manta protos and having owned and/or used the other machines in question extensively, often in direct side-by side comparison with Manta.
27 gold targets over 2 weeks
a BBS type ctx would have obtained between 5 and 10 golds
a tdi 14 volts between 10 and 15 golds
a deepstar III between 15 and 20 golds
I consider the gpx and gpz lower than the deepstar III
(on the beach, they make too much noise with the ground)
P.S. When he says “lower” about the ML machines, he means lower target recovery numbers, not “deeper”.
I want to make sure I understand this fully... You are stating what other machines
could have found? Not tried to find, actually find, hope to find, wish it could find, but could have found... That is "
basing that on years of using Manta protos and having owned and/or used the other machines in question extensively." Honestly, are you being serious?
So a few weeks ago I found a few rings on back to back hunts, me stating machine X could have found 4 of those and machine Y could have found 6? That is now a fact? Could it be "based on my experience" I could make that claim? Since 2 machines on the above list I own, what were the settings on the Deepstar 3? You are aware that it runs at a delay of about 14/15 and stock is pushing 14v, but you could push the power to about 17v and build a coil for more depth. Were any of these things done? The TDI voltage was running very low, if it was a TDI or a Pro that voltage could be bumped up quite a bit. What coil was on the TDI? I could ask about the ground, was it in water, saturated sand, wet sand, damp sand. But want to keep it simple...
Well, I really thought of letting this lay. I wrote this on 3/13/19 in the evening as a reply to your post. Shared it with a someone I trust, on this forum… But sat on it, figured why even post it. You did not answer my questions before, which were straight forward, not a gotcha question. Was curious for all the posting you have done, you did not want to answer one simple question. Then I figured why not... So to answer your long post...
I did not want this to get into another Beach Hunting mine is better than yours thing... I have no skin in the game, zero... As for machines used some of the ones are listed above. There are others but I figure those pull enough weight when talking about pulse machines...
I have also had contact with Reg and Carl years back and also talked with Dan (Guyer) on more than one occasion when the TDI was just hitting the market. Could add others but I do not think that is relevant.
If you want to dig a little deeper, check the username "poseidon" on another forum (not sure about the rules on this forum) and find this thread... "
Difference between Deepstar 1 2 and 3" Who do you think that is? That author also did build coils for the Deepstar 3 for a bit...
I was also aware of the Manta and its website that I found on my own... Interesting, but not earth shattering. This is the only forum I belong to, I like many of the people here, they probably could not all say the same with me, but that is another matter...
Your interest and work are fine, give you credit for that... I read through your posts, all of them... Your comparisons, your beliefs, the things that you have stated on many posts is a fine line between real facts and what you believe or hope. But you stated them as facts. Your eagerness about this machine has turned you into a cheerleader, when you have nothing to back up many of your statements. You said in a post that is was deeper than your TDI... But let’s dig a bit deeper. How many hours have you beach detected with your TDI? (I used a machine you have personally owned) You had the couple "Regs" mods, did it have any others, what coil was being used, how about power (under load) that was going to the coil. The coil, was it a Mono, DF, DD, 000, spiderweb wound? But many posts by you have stated it was "significantly" deeper than a TDI, before and after you tested it. (But I saw a post today that asked you that question and you changed your tune to, you would have to buy it to find out. Why not so definitive?) What is "significantly" deeper? Half an inch, a foot? Am just curious. Smoother than the TDI Beach-Hunter? I own that one as well... How many hours would you say you have hunted a beach in the last let’s say 3 years? With any detector of your choosing…
And now JAG has just posted the machine with a photo of all the rings he found in a certain timeframe. But dig a bit deeper and some of those finds were from other posts, claiming a different timeline for finding them... So if I posted all the rings I found since the start of the year, what does that prove? Not a thing, I got my coil in the correct spot. My numbers for this year that I have and have not posted can hold their own, but it still proves nothing. But I would bet if I hunted the same area as him at the same time, with a different machine and he found more. Your comment would be “see look at what that machine can do!!!…” But what would be your response if I found more than him???
I would invite anyone to go read the threads, go read all your posts... I know a pulse machine is hard to use, one has to stay on top of it and using one is not a turn on and go machine. If one does that they will be losing depth with every swing.
If I think this machine is good, I will purchase it. The cost is not an issue for me. So far I have my doubts with what I already own. I look at the person that after reading all of your threads, goes out and plunks down that amount of money only to find it is a pulse machine. It's ground balance/discrimination sounds like it mimics the TDI which came into being from the GS5. Until I see the specs, I will not know for sure.
This is just one post, one... But is says a lot for many who know pulse machines...
""Although the system in the Manta is quite different than the TDI in its effects - because it is optimized for gold jewelry hunting, the basic principle remains. In all metal you hear all targets. As you increase the "discrimination" (which is an adjustment of the "balance point") high conductors are separated from low ones. Most iron and most silver fall into the high conductor area - therefore if you use the "iron cut" setting where no signal - or a broken up one is returned from iron, silver targets other high conductors will give the same results. In the "multitude" mode of discrimination, low conductors (gold jewelry, etc.) gives a solid high tone and high conductors give a "whoop-whoop" sort of tone. "
So you are saying the TDI is not optimized for gold? Or just gold jewerly? Care to share the pulse width/frequency/time domain of the TDI? I am sure I could call White's tomorrow or show you information which says otherwise. Another thing, could you explain every word in quotes from the above? That sounds interesting, and there sure are many quoted words there, but it sounds like “a ground balancing detector that is running on the same principal as the TDI." That only took me half a sentence to write.
I don't know if you are on Fishers payroll, are friendly with the staff, maybe get some award, personally is none of my business and don't care. For most users, this machine will be better than what they have if they own a pulse. For a user like me, seeing your posts, I seriously doubt it.
I think you are missing the point from your last sentence... I have nothing to gain or lose with this machine. Your reply to me was long on going into who you talked to, what you have owned and how it came into being. But short on the answers to the questions I had directly above your post in bold. Those tid-bits for a reply you gave to me were much different than the avalanche of posts you have written on every metal detecting forum I could find stating what this machine could do... I am not waiting with bated breath or believe once you get it you are going to come to a beach I hunt and "run me over..." You have been pumping this machine with all these "facts" whenever the topic comes up... Will it be deeper than the low powered machines on the market or the past, it should.
But for me, lets say I plunk down my money, get the machine and it is not better/deeper than any of the machines I already have. Can I go to you and say, you posted "this, this and this" why is it not doing what you stated? No I can't, but for me, is a lesson learned… But what bothers me is this... There will be many people who save, may go without something or many somethings so they can buy this machine. How many hours of work will it take them to purchase this machine? Lets just say it is $2200, something anyone reading this can calculate. If they were going on what you wrote, on just about every forum I can find, bold claims about "another gold rush" and pictures of gold in front of the machine... (I will bet more posts by you or JAG in the coming days/weeks giving dollar totals, gold or how this machine is the Golden Goose. You can make what you spent back in a matter of days with finds..) Take away all the fluff, it is still a pulse machine, and if you want the depth you will be running it in full pulse. There will be not one bit of recourse for you and all your posts... Even now do you notice how many have posted “I will wait until someone else buys one, then see…” So who is going to buy it, and what will it be tested against? Convenient in a way, your bases are covered no matter what you post because what are any of them going to compare it to? A low powered PI, a VLF? Be serious...
That is enough, I truthfully doubt you will answer any of this. Actually I did not write it for you. If one person reads this post, goes back and reads all your posts, and maybe reads future posts especially written by you or JAG on the “wonders of this machine” before plunking down their hard earned money before, that is why I wrote it…
