Just picked up a whites dual field Pi first day out for testing.

[Trackerman]

Well lately I've been getting into beach hunting more and more and picked up a dual field from whites. I must say for a pi its a good one and pretty deep as well. I hit a beach I go to on occasion to test it out. To start with the machine is pretty light and well balanced. The coil is 12 inches but skims pretty well in the water and behaves well as far as not moving to much with the waves. The headphones were a bit uncomfortable after 5 hours of use. My right ear was hurting a bit. I suspect from the headphones being very solidly built and have a tight fit. Hopefully they will loosen up a bit with use. Also the area where ones elbow fits was rubbing a bit on a vein in my arm . Which I later adjusted a bit. As far as the smoothness on the wet sand it was overall pretty good with an occasional blip. I had it on the factory triangle presets . It was an ok hunt found some clad and had a decent amount of targets in dry and wet sand. Overall I like the machine a lot. I also have a Tesoro sand shark pi and I must admit the headphones on the Tesoro are much more comfortable than the whites and the sand shark is a bit smoother on wet sand than the whites dual field Pi. But both are good detectors and a great value for a person looking for a good pi. Happy hunting to all cant wait for the next beach trip.

Hey folks,
Just go out and bury that 5 to 7 gm. 14kt. + gold ring at 12 to 13 inches and see how 'OL Sharky detects it...
Don't believe me...
Don't believe the salesmen pushing their little websites...
Don't believe the fan club members (LOL)...

Just go out and bury some real gold at a little better than a foot and see what you find.

Absolutely folks - Do it! You'll see the Sand Shark is just as good or better than a Dual Field, TDI or Infinium! Go out and try it NOW!

Please do. And by all means, be sure to also not look at all the gold that the shark doesn't find, as shown on the fan page!

Use any machine ya like! Me? I'll stick with proven Shark results, and continue to find what you don't.

I agree too. If it works great in your locale, outstanding. If not, try another machine. Good idea!

Depending on how "hot" the Sand Shark is (some are just a little better than others, not sure why) it will get you 10 to 12 inches on a 7gm 14kt. gold band in most wet salt conditions. That is pretty good---and most targets will be located in those depths---which explains why some users have great success with the Sand Shark.

Not 1 in 20 detectorists will take the simple expedient of actually burying a difficult target at depth and testing the machine on that target.

I am not sure why someone would suggest that a Sand Shark manufactured in 2005 with interchangeable coils is not as good as a "new" Sand Shark manufactured with the coil hard wired. Do Sand Shark circuits wear out that quickly? Does the "lifetime warranty" offered by Tesoro not extend to making sure the unit tests to specs? Mine went back to Tesoro...and was returned as "operating to specs"...

Jolly Man: Most likely because corrosion can build up between the pins in the connectors. This may be the reason that Tesoro switched from interchangeable coils to hard wired coils. They may have made this change to increase reliability. It could also have been done to increase profit margins by reducing production cost(s) or to reduce warranty cost(s) from returned detectors. I do know that as an original owner, I would prefer the interchangeable coils for increased flexibility, especially if the life time warranty is honored.

As there is a tolerance in electronic components, some detectors will perform better than others especially if they have been tweaked for performance. Even though a detector is repaired and operates within specifications, it does not mean that it will work the same as when new since the tolerance of electronic components drift over time.

Great point Terry. My experience with the SS (or lack thereof, as you claim) definitely changes how the laws of physics apply to the Sand Shark. If I have only 24 hours experience (which is a poor assumption), certainly Pulse delay or ground balance on a PI are "red herrings."

You seem to know way more than Eric Foster and others who have degrees in EE and knowledge of electronic circuitry. I wonder how you gained such a vast knowledge; and, apparently you have been on at least 90% of America's beaches. How were the beaches of San Diego and Longbeach, WA (where there is so much black sand the beach is nearly black?) How did the SS perform on those beaches? I am sure others are curious as well..... please enlighten us yet again! And please expound on how pulse delay affects a PI detector's stability on beaches. I am curious to see what you know about it. Thanks!

Not that Terry needs any one to defend him as he pretty much speaks his mind, but I would like to clarify a few of what in my opinion are misdirections or misleading statements. When I went to school (a long time ago) Electronic Engineers were trained in circuit design, quantum mechanics, and high frequency wave theory (at least the school I graduated from) where as Electrical Engineers dealth more with motors, power distribution, lighting and some became certified so they sign off on a project when it was required.

An individual does not even have to be technically skilled to effectively use a metal detector, nor understand the theory on how it works. What is needed is an in depth knowledge on how to use that metal detector in the locations hunted, knowledge of the terrain, and how to effectively hunt and retrieve. Above all one has to know how to effectively manage time and have the drive plus physical capability to excel.

As the details on how a metal detector works are proprietary, manufacturers only reveal generalities or what they want you to believe to boost sales. Certified technicians have access to schematics and information needed repair the detector. Some of this may be released to others, what it not released can be figured out by reverse engineering (a timely and difficult process) by which you can determine how a circuit works. But this will only give you partial insight into why it was designed that way or what the engineering trade offs were. The end result is that even the best aftermarket books written by seasoned and successful detectorists are full of misconceptions, faulty conclusions, and poor terminology.

An example of poor terminology is “ VLF detector”. This type of detector is a balanced induction (BI) detector which switches current on and off in its search loop at a frequency(s) in the VLF band. This is important as the FCC regulates the maximum power output in those frequency bands. A common misconception is running hot which has nothing to do with output power. What it means is that you are running at maximum receiver sensitivity which is just below the point that the detector becomes unstable. An exception to this is some foreign detectors do not comply with FCC regulations and some gold nugget detectors which can be easily identified by a knob on the control box to adjust output power and their larger batteries.

I do not know if Mr Soloman benefits financially for supporting Tesoro, nor do I care.
However, I suspect that he would receive better service from them than an unknown, such as myself.
But the same can be said for other successful detectorists who can be identified with a specific manufacturer such as, Fisher, Garret, Minelab , etcetera. They may even receive promotional material and new detectprs to hunt with at no cost to them. Exception for Sandman, who has never received anything for all his help. Jokingly I offered an an older detector that I upgraded from which he considered a toy (inside joke) .

Treasure Hunt Long and Prosper, or Chill out and Hang Loose if stuck at home.

Just did your test. I buried 3 rings. Deepest being around 15". The rings picked up. The signal was faint at the deepest target.

No actually I did do it, the Sand Shark is small gold dead... worse than any other beach machine I've seen. Lets see a 1 gram or lighter ring that you have found... that wasn't within an inch of the surface.

Even the multi-frequency vlfs can see a .5 gram gold ring... why cant the sand shark? (hint: read up on pulse delay and you will find out.)

IF that is your actual result with your machine, i'd recommend sending it back, it's obviously broken.

No problem. Take a look here it shows plenty of "small" gold, in addition to "huge".

I could not agree more! PLEASE read up on pulse delay, as it will debunk all the misinformation this forum member and his two buddies continue to type - point blank. Now, I know folks that spent twice what they would have paid for a Sand Shark do not want to hear the Shark is just as good as their machine on the beach, but hey, there it is.

You forget, I am one of the disgruntled people that you "tricked" into buying that mediocre machine... It may work well on your light to medium mineralization on the east coast (and apparently your nugget spots in Arizona...), but Multi-Frequency VLFs work well in that ground also... in very hot ground where you actually need a PI, its a useless and expensive paperweight.

Please Terry, since you are the Pulse King, explain to us what Pulse Delay does, and why it makes no difference as far as sensitivity is concerned. I could use a laugh...

 

[Trackerman]

Every detector has its pro's and cons. The Dual field for example has very good depth but horrible hard uncomfirtable headphones and the main box and arm cuff could be better durability wise and confortwise. So the Sand shark is not as deep granted its still a decent pi that as far as contruction and confort goes is better than the dual field in that catagory. The main box is built more solid on the shark and the headphones wich are very important by the way bieng that there conected hardwired on both machines are way more comfortable on the Sand shark. But still both are decent pi's and should produce some good finds provided there are good targets and a decent beach.

You are simply "disgruntled," period, "Nameless." All I can say about your claim that I somehow "tricked" you into buying a Sand Shark is, why would you even post such foolishness?

And no, a multi-frequency detector does not work well for hunting gold nuggets - anywhere. Your opinions do not have anything to do with the reality that I can find anything you can find with your Infinium - on any beach - with the Sand Shark. didn't even have the integrity to use my name in his "edited" response to a thread he deleted then cited: "Originally Posted by Another Member," Where I wrote: "There is a lot of controversy over "Pulse Delay," and its importance to depth and small target sensitivity. Unfortunately, most people don't understand that a setting of 10us pulse delay, is very noisey and unsteady on wet ocean sand. So even though you may be getting more sensitivity to smaller targets, you might not hear them. Now, move your coil from the wet sand and into the water and you will have to increase your pulse delay to at least 15us to smooth out the threshold. By the time you have reached a depth of five-feet in saltwater, you'll need a pulse delay of about 20us."

Then he edited out my Eric Foster quotes "..." where Eric talks about the real differences in sensitivity (which is almost nill) between 15us and 20us, and continued my words, "The pulse delay must be coupled with power to the coil, and circuitry that filters and reads the return signal. The performance of a machine is NOT based soley on pulse delay. That is my opinion, and why I think I would rather have a set pulse delay of 20us, than 15us."

I am not "the pulse king," Nameless, but I find a lot of gold and have been using Pulse Induction machines since the early 1990s to find it. My advice to beach hunters has always been, and will always be - Don't waste your money on a $1,000.00+ PI for the beach when a $600.00 Sand Shark is just as good or better.

Terry, it is easy to prove that increasing pulse delay makes the machine lose sensitivity, just bring a few older nickels to the beach and bury them in the wet sand at varying depths. Then turn on a PI that has a pulse delay control, swing over the targets at minimum pulse delay, then increase delay, swing again, etc., the results are obvious. I show it in my Infinium air test video, that minimum pulse delay (10-15uS) picks up a .45 gram ring at about 6", and at 3 pulse delay (roughly 25uS) the ring is no longer visible even touching the coil. The same thing happens at the beach with targets in the ground. Explain that...

The simple fact is, you want to sample the ground as soon as possible after the ground signal from the pulse returns to zero, to catch small/deep gold that decays shortly after the ground does. If the ground takes 14uS to decay to zero after each pulse, and your machine is locked at 22uS sample delay, what happens to that deep/small gold ring that takes 16uS to decay? The answer is you miss it, while the Dual Field/Infinium would have seen it. Also, what happens when your ground takes 25uS to decay to zero and your pulse delay is locked at 22uS? The answer is your machine sees the whole ground as a target...

PS. There is also a thread somewhere where Eric Foster himself says that the Sand Shark is mediocre... something to the order of, he tested it, it wasn't up to par, and was quickly dismissed.

PPS. I love how when you are asked to explain Pulse Delay, you google it then just copy/paste... so you don't actually have to learn something... cute.

 

[Aka Nameless]

I love typing up a long reply to you with facts, and you simply don't read it, and don't acknowledge anything I just said.

Go do some tests dude, you will see that your machine is mediocre. I've done the tests, I know the truth.

Your undying love for that crap PI makes me hate the Sand Shark even more.

You sure are an asset to Tesoro... I should call Randy at Tesoro and show him how much hate you bring to Tesoro, then maybe he will think twice about hiring you as a walking advertisement.

 

[Terry Soloman]

Getting a little frustrated "Nameless?" You poor thing. I'll pray for you.

 

[DewGuru]

you will see that your machine is mediocre.

I'll keep using my "mediocre" machine. The gold poundage found with it thus far warrants no other.

Happy Hunting!
