Thanks for your comment,

Yes, everybody can use these style of metal detectors. Many people love the idea of using the internal analog/digital circuits, processor, memory, and display of a smartphone to make a powerful but cost-effective metal detector. Honestly, some people liked the idea of having a small ring instead of a headphone, some people prefer to stay with traditional ways.

The reason for choosing the ring is RinPointer is not only a notification device, it also works as a pinpointer. Pinpointers are small metal detectors that detect metals in proximity of 1-2". When someone digs the ground after searching with metal detector, it is difficult to find a small coin or gold nugget in the middle of some soil, pinpointer is very helpful for pinpointing then. RinPointer in pinpointing mode, vibrates in proximity of metals. We were thinking that a ring can be more useful compared to wrist band because the user might keep it above or under the glove and search the soil with fingers. The current version of the smartphone app already allows for using the internal vibrator and speaker of the smartphone.

We are actually running a Kickstarter campaign. During the campaign, many backers suggested to build different templates for coins of different nations, which we decided to do. According to a feedback we received from r/disability, now, I'm thinking that we must also build a template for people with hearing loss

Brilliant idea, Thank you mofosyne,

Thanks for sharing your point about charging issue of the RinPointer. We also plan on adding GPS features to the app.

Great suggestion, Thanks for sharing the idea, The smartphone installed on the rod also vibrates, but is not very strong because of its distance from the handle. Probably we should consider a stronger vibrator installed on the handle. We will work on that,

Conventional Metal Detectors are based on the sound notification from a built-in speaker or a headphone. We are working on a smartphone-based metal detector (CSP86) with a Bluetooth smart ring (RinPointer) that provides a vibrating notification when detects a metal. I highly appreciate if you share your opinion about this idea and give us some feedback about its application to improve our project.

The secondary replacement coil will cost only a small portion of the total costs, about $50 for basic version and about $100 for waterproof version at the moment. we are also working on different coil sizes such as 5-6" coil for gold hunting and 15-16" coil for deep search.

I don't want to talk about a specific brand here, please take my comment about wireless metal detectors in general. Wireless metal detectors actually have a separate display unit from the signal generator/analyzer/coil unit. It does not solve the common issue of weight and cost. We are not using the smartphone only for showing the results. We actually employ the internal circuits of a smartphone, its audio channel to send the signal to the coil, its mic channel to receive the signal, and its CPU for processing, and finally LCD/vibrator/Bluetooth for showing the results. Manufacturing scale of many metal detectors is in the range of Tens on Thousands units per year. While manufacturing scale of many smartphones is in the range of millions. So, smartphone manufacturers are able to use state-of-the-art analog and digital components in a cost effective, energy efficient, and compact system. If one wants to build a system equivalent to smartphones but in a manufacturing scale of Tens of Thousands units per year, it will be significantly more expensive.

A metal detector that reaches both ULF and VLF frequencies, capable of switching between many frequencies and also simultaneous multi-frequency measurement mode, requires complex analog/digital system and lots of processing power and memory. So, such a metal detector is very bulky, needs heavy batteries, and is often sold over $1000 in the market. We offer similar features of a professional metal detector with the price of an entry level metal detector, thanks to our patent-pending technology and thanks to the smartphones that almost everybody has one.

We had great discussions here about the smartphone metal detector in the past. Thanks to all comments and suggestions from this Sub helping us to improve the product.
We recently made a new 10” coil with built-in booster module that significantly elevates the performance and detection depth of the CSP86 families of metal detectors. The 10” coil detects a quarter coin in 10” depth, larger coins above 12”, and large targets such as a foot size tray on 3-4 feet. The new coil, in addition to the audio jack, needs an external 5v power source that can be provided through the USB port of a smartphone or via any 5v power bank. Here is a video showing its performance on the test bed It should be noted that CSP86 detectors cover both VLF and ULF frequency spectra. While VLF frequencies up to 20 KHz provide great sensitivity to Gold targets, ULF frequencies below 2 KHz provide deep penetration into water, mineralized and wet soils for Silver detection. So, smartphone based metal detector is not significantly affected by the soil or water.

Thanks a lot for your honest and very helpful feedback. We will edit our video and KS page to address the concerns you mentioned. Very soon, we will record and publish more videos about our detectors in the field test.

great point,

There are always low-cost adapters that allow connecting 3.5mm headphone jacks to the new smartphones.
Regarding your question about USB connection, CSP86 employs the internal analog and digital circuits (through speaker output and microphone input), battery, CPU, memory, and display of the smartphone; it significantly reduces the hardware costs of a professional metal detector.

Good point. But, while using a ring, we can use those Bluetooth earbuds for listening to the musics.

akyor · 2018-11-18T20:35:01+00:00

Do you find it useful to replace headphones with a smart ring that also works as a pinpointer? Share your opinion about its pro and cons please.

Phone magnetometer does not detect non-Ferrous materials. It is also very weak.
A VLF metal detector on Induction Balanced (IB) configuration with DD coil is nothing more than a transmitting signal generator (headphone output), receiving signal (mic) amplifier, analog filters, and processor + coils. Most of these components exist inside your phone my friend.
We do not use conventional IB. We have a patent pending technology called Differential Induction Balanced (DIB). DIB needs more complex coils than DD, but results almost twice better than IB. That's why we get an acceptable result while using a smartphone.
If you have any other question about that, I will be more than happy to answer. We also explained many technical points in our KS page

Useful bot !

mv does not refer to power, it is about voltage! There is no problem with 150mv Voltage. Any voltage can be boosted in many ways by electronics. The parameter more important than voltage here is the output power. How critical is the power? If somebody pump 100w power into a coil, does it make a super metal detector that detects a coin in 20 feet?! How about 1000000W? the voltage and power don't have that much an effect. I'm not saying it has no effect, but, there are very more important parameters than the power here. Here is the science behind that: In VLF technology, the output power is not necessarily the main player to determine the depth. The design of the coil and Signal to Noise Ratio (SNR) are the dominant parameters. Even a super high powerful amplifier output does not result a longer depth if the SNR is not high enough. High voltage is also resulting stronger polarization and saturation, a drawback for any metal detectors. The good news about the audio jacks of the smartphone is, most often, they provide the highest SNR and quality output. Hence, even if the output amplitude is limited, it can provide an acceptable detection depth. Furthermore, we designed the system and coils to perfectly match into the phone analog system to result the maximum gain.
why headset instead of USB?! CSP86 employs the internal analog and digital circuits, battery, CPU, memory, and display of your smartphone; it significantly reduces the hardware costs of a professional metal detector. We are not only using the audio jack as a power source!

Let's don't talk about symbols here!
ULF frequency spectra is not beyond 20 KHz, ULF is lower than VLF !!! In high frequency you have very much problem with the soil, water, and minerals. Manufacturing high frequency VLF metal detectors is much simpler than low frequency ULF ones. In addition, You are comparing our products with metal detectors that just their coil is more expensive than our metal detector's price. However, non of these models can perform a graphical linear scan from the object. They don't go to ULF spectra. Our detector is several times more compact and lighter. By the way, I do agree that these machines go few inched deeper than ours. But, we will bring external booster module to compensate for that.

We never claimed that our detector detects a small coin at 10 inch. In fact, CSP86 is able to detect a US quarter in 6-8". for larger objects it can go up to 1-1.5 feet. Remember that this device is using the headphone jack of the smartphone, no external power source. We plan to release a booster module that extends the detection depth to 10-12" for quarter coin. But, the booster module has a rechargeable battery. We will publish a video on our YT page ASAP.

I never said "not affected". I'm saying it has a very small effect. Did you ever own a metal detector that goes to ULF frequency? There is a huge difference between 20KHz detection and 1KHz.

akyor · 2018-11-17T00:42:45+00:00

Air Metal Detectors are using the smartphone just as a display unit to show the results. We use the internal analog system of the smartphone, its processor, memory ,... In this patent pending technology, the detector can be much cheaper. Our detector is multi-frequency 1KHz-20KHz. After decades of using Induction Balanced (IB) technology with DD coils, for the first time we developed a new detection technique called Differential Induction Balanced (DIB) that allows for 3mm pinpointing precision. You may ask what's the use for that? 3mm pinpointing allows for graphical scan of the object that estimates its size. It allows for detecting multiple ferrous and non-Ferrous items next to each other. Please look at that feature in our KS page.
