Pulse Detector Depth Proformance

[Qiaozhi]

Hi 666....i feel sometimes this detectorist is just using me to promote his detector...to be honest whatever !!! some of his idea's have come from other people's design's like eric's gs 5 so he is just a copier of other peoples technology...if he was that cleaver he would design from his own mind...i feel such a fool now in telling people about this detectorist...im just too naive for my own good.

You also have to remember that depth measurements are somewhat subjective, especially in sand. When you add in any personal bias to the results, you get the ultimate detector.

G'day Dave, looking forward to this fellows youtube video and his ID display

You have to remember that ring-shaped targets are the easiest to detect. Also, he doesn't need to go down to 9us delay to successfully detect coins and rings, and with such a low sample delay there will be lots of false signals from salt water.

Dave - I know you have the Surf-PI, but what other PI detector kits have you built?

Hello George.....Nearly all my projects have been based on surf pi with modification...i did try the hammer head some years ago but had problems so i didnt spend much time on that...i really like the surf pi as it fits into plastic tubes and is very straight forward in construction...i have other pcb's like mirage...mini pulse...cross bow....but ive never got around to making these...im very slow at times in doing things...i want to try other designs but sometimes it hard for me to motivate myself cause of my problems.....sometimes i think it would be easier just to have a good commerial detector like gs 5 or tdi pro cause it gives me more confidence in finding something nice...when things improve for me money wise i will try for sec ondhand tdi pro maybe in the future...and go and kick some butt on the beach

Hi Tony & 6666.....i have sent a text to this guy and mentioned to him peoples thoughts on his detector and he replied to me and said once he has fully completed this detector like including ID display he is going to post his detector on youtube for all to see so it seems he a very adament about his claims about depth on gold rings..but in any case im not that concerned any more but just want to try and pull myself up and whatever i find or dont find its just being happy with what i can do...as life is too short to worry about these things

Hi 6666......To be honest he is not a friend but someone ive known for many years who makes his own metal detectors and is a beach detectorist...he made also a non pulse machine which is a vlf motion/non motion type with a single coil and full discrimination which he
has used for some years now and has been very successful with it on the beach in the summer.
I guess it will be interesting to see if he can do this ID but without iron disc...he stated he may use a separate ferrous spear type item
to ID iron.....i was at one time going to try and use magnometers to try and reject iron but seems to difficult to set up in a mechanical
way...at present im really trying to push myself to get my detectors sorted out...but my low mood swings are hard for me to overcome

daverave, glad to see some positive statements from you

There are a lot of variables going on here, I would call this mate of yours and get him to meet you at a beach, bury a ring at 18 inches and get him to prove he can detect it.

[Tony2]

Absolutely.....now you are seeing the true picture. Empower yourself and call out your friend with his claims. Tell him there is this guy in Australia who is planning to fly out and wants to meet him and film this amazing new coil and has his cheque book in hand. Let's see what sort of reaction you get from him.
You most certainly are not making anyone here feel bad...quite the opposite actually. It sounds like you are on the positive mental path, stay on that path, be your own person, remember seeing is believing. The irony is "your friend" is the one with issues and has to resort to certain techniques to boost his well-being.....stay away from these people as they are toxic. Take some deep breaths and keep feeding your positivity and you'll be just fine !!

Hi Tony....maybe this detectorist has made these statements to make me feel bad and to make me more depressed !!! ive got to try and toughen up and not listen to no more crap from this guy !!! i have my good and bad days but im really trying to get my act together and be more positive....i didnt mean to make people feel bad on here by saying about the claims of this detectorist but i guess im too naive in believing what people claim

Dave
Having met you and been in your workshop the quality of your builds is excellent, I think you have answered your question when you say the others spend a lot of time out detecting. Learning to "read" the beach is the advantage they have which you can only get by spending time on the beach.
This for many people is a race to win hobby, they must always have the best and deepest machine and get the best finds. A few years ago I saw a guy did up a gold sovereign did the same 2 weeks later second time I saw him calmly walk to where the cameras were, he made no attempt to search the area around the find site??????. Another guy tried to convince me that he could get finds at 18-24" depth based only on the number of shovelfuls of sand he dug.
Has this guy seen the quality of your detectors and the only way to "win" is lie maybe. Bob

Hi Bob...it was so nice to meet you in person and have a good chat..i appreciate your kind comments concerning the detectors that ive made...im going to try and not give up so easily in the future..now the warm weather is coming i will try and get out more..maybe keep to myself more on the beach so peo ple cannot come up to me showing off their detected cash and rings

This is absolutely the correct attitude. Measure everything yourself.
Unfortunately there are those who always want to be on top of everyone else and for that they will claim anything.
And there are those who are simply inaccurate in what they believe.
There will be always someone who's piece is bigger at least in their mind.
Don't pay them any attention.
The moment you feel that someones gibberish makes you feel anything but happy, just walk away.

24" on an average 9ct ring.......tell him he has the deepest detector ever created by mankind. 40% deeper than my GPX4500 on it's most powerful setting.
Tell him I will pay him $50,000 for this detector...no questions asked.
Sorry but "his claims" are impossible....12" on an average 9ct ring is not bad. I have used just about every PI over the past 15 years (beach and prospecting) and the internet is full of BS "claims".......any pulse delay of 10uS is for dry sand only and not surface dry but dry down to to a foot or so.....top of beach only. These claims should be banned from the internet as it gives newer users a totally unrealistic expectation of what detectors can achieve.
Tell him White's or Minelab will make him an instant millionaire with his amazing new coil.....

Dave I used to get very depressed in winter, but I now take vitamin B and D supplements from mid autumn to mid spring and I think they really help me not to sink too low.

I think your associate is using reverse psychology on you, he knows that confidence is the number one prerequisite of a successful hunter, and he is aware that nothing shatters confidence more than the belief that your machine is deficient in some way.

Others here have really hit upon what is more important than outright power, maybe you should note some of them down and give it some deep thought.

I know from my own experience on the beach, that to say that all the good stuff is now too deep is just not always correct. The sand is always on the move, making the depth to hard-pack variable. The different strata-layers are never equally thick across the whole beach, they are angled and taper into each other.
One of the most powerful things you can do to improve your finds is sharpening your observation skills, with respect to beach morphology. There are a number of books dealing with this subject aimed at the detectorist that you may be able to find second hand. I assume your avatar is you and I see you are walking the "wet line" so you already know one area to focus on. There are many more depending upon your type of beach and offshore conditions.

One factor that could change everything tomorrow for you, is climate variability. Perhaps after you get a good unseasonal storm, the whole lot will be stirred up again and good finds will be more regular for you.

In hunting for gold nuggets I regularly bury a target at the threshold of detection and check my settings are optimal on the day. A key factor when seeking very deep nuggets is the response and recovery speed of the machine. One of the biggest mistakes we can make as a detectorist is sweeping the coil faster than the machine can respond to the target. That time is greater the deeper the target sits, since it audibly registers on less of the coil area if it is a small target. This is one of the main factors why many GPZ7000 operators were unable to get the extra depth advertised with this machine, it requires a consistent slow sweep on very deep items.

Swapping between PI and VLF can compound the sweep speed problem, since one is usually processed by an integrative function while the other differentiative where depending upon filters used may have a faster sweep enhancement.

Bottom line Dave, technique and knowledge, they are just as important as your preferred tool.

hi Kev...I think your right when you say about reverse psychology...some people want to make me feel bad by saying their detector go's deeper and makes my detector feel inferior to theirs...in the summer the same detectorist boasts about his finds on the dry sand and shows a handful of coins which makes one want to give up and go home...yes its reverse psychology !!!! maybe i just got to toughen up and ignore these people that try and make me feel ****...i think also with detecting its being in the right place at the right time...my main problem is that im not good at reading beaches...my favorite detector of choice is pulse and i hope in the future to get a pulse detector that will give me some discrimination on iron for the dry sand...for me pulse is the best for the dry and wet sand.
