I have set up a G-882 system here at Geometrics and am receiving data and sending commands using TeraTerm (any terminal emulation program should work). When in normal use mode the Digital add on board sits in front of the G-882 and parses and acts on all commands coming in. There are two versions of the Digital Add On board, which are the GP120 and the GP140. The GP140 is a newer version of the Digital Add ON board. It is the GP140 Digital board that outputs all S/N (and other) information. I first set up with the GP140 board (the newer version). I find that the ""RESET" command does work - i.e. it goes into BYPASS mode for a couple seconds, then output the S/N and configuration information, and reverts to normal operation with the digital depth and altimeter information. But it only works every other time I send it. The first time nothing happens. Then I send it again and it works. This appears to be a bug in the GP140. For some commands the first command after power up or reset are ignored. The second time (and subsequent commands) are executed. The work around seems to be sending the RESET command twice. I also tried an older G-882 with the GP120 Digital board. The Reset (and other commands worked first time and every time. BTW, the Digital Board version is in the second line with the S/N information that is sent on power up or Reset. Some questions: 1) My configuration is one G-882 connected to a PC through the white junction Box. Is this your configuration, or do you have concatenated G-882's? 2) Can you get the G-882 to accept any commands (like going into Bypass Mode)? I'm wondering if there is a open link in the command line from the PC to the Digital board.

If the compass readings are accurate and its 3 axes are perfectly orthogonal to each other, the vector sum of 3 compass readings (x,y,z) should be very close to the MFAM reading, assuming the local gradient is small. However, due to two main reasons, very often customers find a big difference between the vector sum and the MFAM reading. 1. The compass inside the MFAM driver Box is NOT a top-rated vector magnetometer, in terms of reading accuracy and axis orthogonality. A top-rated vector magnetometer, capable of producing good vector sum readings, costs thousands of dollars and is much bigger in size. 2. The compass is integrated on the MFAM driver board, which has many magnetic components. The magnetic field at the compass location is altered by these magnetic components. Although the compass doesn't generate good absolute readings, its relative angle measurement (related to the reading repeatability) is good enough to be used for maneuver noise (heading effect) compensation.

Description of Issue: Is it possible to download data directly from the sensor/datalogger Box to a PC/laptop through the WIFI connection without using a USB drive?

You can use the tape.exe application that was installed on your computer when you installed the Seismodule program. Read in the SEG-file, convert it to ASCII by selecting the File menu and Convert to ASCII. Check the Box to convert to mV. Once you have converted the waveform to ASCII voltages, you can multiply by the sensitivity of the geophone to recover true ground amplitudes. Download Tape Reader. IMPORTANT - Be sure to back up your data files before running this program.

There are basically three types of "gold": low concentration disseminated gold in ore, placer gold deposits and solid gold such as that associated with treasure. Magnetometers are used to find disseminated gold by its association with mineralized zones which also contain magnetite or other magnetic minerals. Magnetometers are often used in conjunction with airborne electromagnetic surveys to find the conductive ore bodies. Placer gold is the type found in buried stream channels such as the gold which sparked the California gold-rush in 1849. Gold dust and magnetic minerals have been concentrated in river banks over thousands of years. Where there is gold there is often magnetite and therefore the magnetometer can be used to locate placer gold deposits. Gold treasure is a different story and being non-magnetic gold, silver, and other precious minerals are not directly detectable by the magnetometer. The magnetometer can only detect ferrous (iron or steel) objects. If the gold is stored in an iron Box or has iron materials next to the gold (such as colonial ship ballast stones in the marine environment), there is the possibility of detecting the iron material. This is true for land and marine (sunken galleon) gold bullion. The vast majority of target search surveys are performed on a grid in a "lawn mower" back and forth manner to cover the area of interest. Lane spacing is dependent on target size (magnetic mass). At a sensor to target distance of 2 to 3 meters there will need to be at least 1-2 kilograms of iron. This can produce a 1-2 nT anomaly that is detectable in a magnetically clean environment. The ideal environment would be in a plowed farm field or the bottom of the ocean away from human activity i.e., away from a port or harbor. You will probably not be able to detect this small of an anomaly in a city or port location. The more iron mass there is, the better the chance of detecting it. Training to use the magnetometer can take 1-2 days depending on experience with setting up computerized survey equipment and a GPS. Processing the magnetic data requires several days of training and would require a geophysical background to interpret the final maps. We provide free software to make maps and estimate the target depth of burial (inversion). If you are unfamiliar with this procedure, we would recommend that you find a local geotechnical firm to look at the data to determine if there are anomalies that should be investigated further. Remembering that non-ferrous materials do not cause anomalies (gold, silver, copper, brass, aluminum, gems) you will be looking for anomalies either associated with the container OR associated with ground disturbance (i.e., gravesite). In this way some anomalies can be detected where there has been an excavation such as a gravesite. In order to understand the process more fully, we strongly suggest that you download and read the Applications Manual for Portable Magnetometers. Other additional resources are available. Understanding how the magnetometer functions and how the earth’s field responds to distortions due to ferrous materials will help you make good decisions about how to interpret and use the data to direct recovery or exploration efforts.

You will need to test the magnetometer on the dry deck or in your shop. Connect the G882 directly to the junction Box and use the black power supply Geometrics provided. Verify operation. If working go to step 4. If the magnetometer is not working, then there is a hardware failure. There is nothing that can be done in the field at this point. Arrange to send it in by requesting an RMA number from our RMA page. If the magnetometer is working then "dies" it would be useful to have the data from the "diagnostic survey". Review this document: Diagnostic Surveys for CM221 Counter Equipped Magnetometers r-2. Connect on board power supply (if different than the supply already checked) Verify operation. If it fails record Diagnostic Survey. If working proceed. Connect Deck cable (if applicable). Verify operation. If it fails record Diagnostic Survey. If working proceed. Connect Tow Cable. Verify operation. If it fails record Diagnostic Survey. If working proceed. Deploy magnetometer under normal configuration. Begin a Diagnostic Survey. If the mag doesn't work under tow then there is a problem with the tow cable/interconnections. Please take these steps and record the data when a failure occurs. (Best to record data all the time and then when it fails send the data to our Support Team, you can contact them through the support contact form. Make sure you are specific as to the conditions/configuration if/when it failed.)

The MagArrow uses a 3 cell Lithium Polymer battery to power the MagArrow during surveys. The two main requirements for the battery are that it must fit into the battery compartment, and it must be nonmagnetic. Non-Magnetic Batteries: Some types of Lithium Polymer batteries are extremely magnetic. This is because the cell-to-cell connections are made with nickel strips (nickel is extremely magnetic). This makes them unsuitable for use in the MagArrow since they will interfere with the background magnetic field that is being measured. Whether or not the batteries are magnetic is not something that appears on the data sheet, so it is important to choose batteries of a particular construction form factor that in practice has been shown to have a very low magnetic signature. Examples of this battery type will be shown below. There are many brand names for this battery type, and the brand names seems to change frequently. Evaluating the Magnetic Properties of a Battery: Batteries should be measured for magnetic signature before using them. This is especially true when trying a new battery brand just to be sure the battery is not going to affect the survey data. To perform this test you will need to start a survey with a stationary MagArrow pointing north-south on a nonmagnetic platform (wooden sawhorses, cardboard Box, etc). Hold the battery to be tested immediately over the battery compartment and rotate it in all orientations. Download the data and look for variations in the magnetic field that correlate with the battery rotation. There shouldn't be any correlation above 1 nT peak to peak. Make sure the operator is nonmagnetic when doing this test (shoes, belts, watches, cell phones, keys, etc. can all corrupt the results). Battery Size and Shape: The correct batteries are rectangular in shape and measure roughly 105x34x24mm. They are made from 3 flat cells stacked up measuring 11.1 volts nominal. They should be between 1800 and 2200 mAh (milliamp-hour). Higher capacity batteries will not physically fit in the battery compartment. Lower capacity batteries will work, but with a reduced run time. One 1800 mAh battery will run the MagArrow for about two hours. The MagArrow power connector is XT-60 so the battery must match. There are other power connector types, but XT-60 is commonly used. The 4-pin balance port connector is a JST-XH4 connector (though this is standard on most batteries). Where to Find Batteries: If you are in an area that doesn't have strict controls on shipping Lithium Polymer batteries, then Amazon.com is a good source. Another good source is hobby stores, or anyplace that sells radio-controlled toy cars, boats, or airplanes. This is typically where this style of battery is used the most. What do the Battery Specifications Mean? 3S: This means it is a stack of three Li-Po cells Voltage: A fully charged 3 cell Li-Po battery measures 12.6 volts. A depleted battery will measure 9.6 volts. Thus, the voltage for this battery is typically labeled as 11.1 volt (the average of 12.6 and 9.6 volts. 35C (or any other "C" value): This is a rating on how much current can be safely drawn from the battery. To get the value in amps, take the milliamp-hour rating and divide by 1000 (to get amp-hours), and then multiply by the "C" value. For a 2200 mAh battery with a 35C rating multiply the 2.2 amp-hour capacity (2200 mAh / 1000) times the C value of 35, which gives a maximum discharge current of 77 amps. The MagArrow draws about 0.6 amps, so any C value is fine - even if is down to 0.5. Battery Chargers: Most battery chargers being sold now are universal chargers which support a variety of rechargeable battery chemistries and output connectors. They come in many sizes and shapes, but most of them operate identically because the internal circuitry is the same. Most chargers will charge at a much faster rate than the MagArrow discharges them, so you technically only need two batteries in the field. A nice feature to look for is the ability to power the charger off 12V as well as with AC power. This will allow charging in the field off a car battery. Be sure to charge in batteries in "Balanced Charge" mode using the battery balance JST-XH connector. This allows more charge current into cells that are more deeply discharged than the others and ensures that the battery gets all three cells completely charged. Battery Safety: Lithium Polymer batteries are small and light but store a tremendous amount of energy inside. This is good for running equipment for long periods of time between charges, but it also means that if something goes wrong and it releases all its energy at once it can be a serious fire hazard. Never charge a lithium battery unattended, charge only in a fireproof location. Batteries that are swollen or damaged should not be used. Dispose of these per local regulations. Be sure to follow all regulations for shipping or hand carrying Li-Po batteries. This may include packaging and labeling requirements, limiting the number of batteries, and discharging the batteries to 30% capacity before shipping. Do not discharge the battery below 9.6 volts (3.2 volts per cell). This damages the battery and could result in destructive decomposition and fire. If a battery that is discharged below a safe level is placed on the battery charger it will refuse to charge it. Batteries that are discharged below 9.6V should be removed from service and disposed of according to local regulations. To download a copy of this document as a PDF, click here.

A customer reached out to support about inconsistent arrival times on stacks using his ES-3000. After stepping through the set up, he sent the .dat files for us to look into. It was mentioned that the seismograph itself is not capable of randomly triggering early and that there was something external to the instrument causing this 100-200mS early trigger event to occur. Another puzzling factor was that it occurred randomly after a number of shots in auto-stack mode (10). It took some investigating and convincing, but what was finally concluded that the sledgehammer in use had some "flex" in the handle that would cause a "pre-trigger" on the downswing. Once the hammer was replaced the pre-triggers ceased.   Thanks again for the time on the phone today. I really appreciate the guidance and experience of your team.   After the discussion with your team, this led me to do a few more tests on the equipment. This evening, I got 40 stacks with no inconsistency in arrival times.   To close the loop on what I think was going on: I believe the hammer itself may have been the issue, husky hammers have a shock absorber and a sloped handle. Having the trigger strapped in a particular way on the hammer may have been the cause here. See image below:   Attachment : Husky Hammer.png   I used a new hammer (NOT HUSKY) and did not experience the inconsistent arrival times. I will continue to monitor the issue. I appreciate the support from your team! I've individually swapped out all other components (aside from the geode) - this is the only change that seems to have solved the issue.   In summary: My theory is either the shock absorber, or sloped handle caused the trigger to delay, resulting in early arrival times.

Hello, I wanted to try our MagEditor software, but it didn't accept any of the files I converted to 10 Hz, 20 Hz, 50 Hz, 100 Hz, and 1000 Hz CSV formats from Survey Manager. What's the reason and how can I fix it? My operating system is Windows 11 Home Single, and my computer specifications are:Processor: Intel(R) Core(TM) i9-14900HX (2.20 GHz)Installed RAM: 32.0 GB (usable: 31.6 GB)System type: 64-bit operating system, X64-based processor.

Hello everyone, my name is Devan, and I would like to open a discussion about finding a lost MagArrow. To give you some background, I lost my MagArrow II while it was mounted below the DJI M400 during a flight mission in a highly dense forest. We have the drone flight log, which indicates that it was stuck in a tree within a 50 m radius of the last known location. We have searched the whole area, but due to a highly dense forest and steep terrain, it was very difficult to find the MagArrow II and the drone on foot. For more than a month, I presume it was still perched within the tree canopy. And now we have bought a new MagArrow II to continue our survey. In this case, I desperately want to find and retrieve the lost MagArrow using the new device. I have an idea that if I conduct a 5 m spacing grid in both East-West and North-South directions within a 100-meter radius of the last known location, we could eventually narrow down our perimeter by finding an anomaly that indicates the lost device. Therefore, I have a few questions:1. How magnetic is the drone and the MagArrow II?2. Is it feasible to find the old MagArrow with the new MagArrow with the stated method? Alternatively, do you have any effective suggestions for a different approach? I appreciate any insights you can provide. Thank you!

The 1PPS pulse phase locks and synchronizes the sample interval to be in lock step with the GPS. Thus once locked there will always be 1000 samples per second, with the sample beginning time precisely lined up with the 1 PPS edge. The 10 MHz input is for a different function. This input phase locks the 40 MHz master reference oscillator to the incoming 10 MHz, which is usually a GPS disciplined reference oscillator or atomic clock (in other words exactly 10 MHz). This phase locks the 40 MHz reference oscillator to exactly 40 MHz. The 40 MHz oscillator is the time base reference for calculating the Larmor frequency, and therefor the magnetic field value. Even though the 40MHz oscillator is really good even without the 10 MHz input, there is some drift in the 40 MHz over time (mostly thermal drift and some aging). For some applications where they need to measure very low frequency and low amplitude changes in the magnetic field the 10 MHz input will allow drifts in the reference oscillator to be removed. Without that it would be impossible to distinguish between reference oscillator drifts and low frequency low amplitude changes in the magnetic field. The connector for the 10 MHz input is SMB RF connector from Molex. If you must simulate the 1 PPS signal in a GPS denied environment, please be aware of certain requirements of the 1 PPS signal. 1. The lock range for the 1 PPS input pulse is very narrow. The simulated 1 PPS signal must be within 100 ppm of an exact 1 Hz PPS signal (100us). 2. Timing jitter must be small (less than 0.5 ppm, 0.5us) too. If you are setting a GPIO pin on a microcontroller, there may be some concern about timing jitter due to interrupt latency or other processor tasks delaying the I/O pin toggle. Any rectangular waveform should work but the leading edge must be very close to 1 Hertz. It is the positive edge that specifies the 1 second rollover.
