Survey Manager may exit without notice or it may show some information about the failure, including steps to open a service request with Seequent.

On systems with Montaj 2025.1 or earlier, this issue may be fixed by updating Montaj to the most recent version (2025.2 at the time of this post) and verifying that Survey Manager is at its most recent version (3.5.1433 at the time of this post).

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!

Thank you in advance for your assistance!

1. Download and unzip the file below to your local computer.

2. Make sure the installed MagLog program is not running. If it is running in the background you will need to go to the task manager and manually close the program by selecting end task. For those that may have used to compatibility work around, revert back to default by unclicking Compatibility mode in the Properties>Compatibility menu of the MagLog software.

3. Navigate to the folder where the unzipped files are. Double click and run the "maglog2017.exe" file.

4. Once the MagLog user interface pops up, the software is updated. Close the program.

5. Now the installed MagLog program should be compatible with Windows11 even after the downloaded files, including "maglog2017.exe", are removed from your computer.

Please leave a message below if it does NOT work for you!

A new MagLog installer will come out later.

Note: according to a customer this is how the switches are set as they are attempting a file transfer at 115200 BAUD.

Connect the G-857 to the computer using the download cable and a properly installed USB/RS-232 adaptor. (Must have FTDI):

Open the MagMap Software.

Select Import>G-857/ASCII

1. Enter known Serial Port (My computer is COM4)

2. BAUD 115200 (Switches 6, 7 and 8 off)

3. Set a good location for the file to written to.

4. Leave Download only, open later unchecked.

5. Leave download time out 2.

Select OK.

On the G-857 press OUTPUT, ENTER when this window opens.

BYTES DOWNLOADED will begin to increment.

Select OK in the window below:

The downloaded Mag file should be displayed:

If the download sequence does not happen this way, it is usually a problem with:

1. USB/RS-232 Adaptor not FTDI, or driver not installed.

2. COM PORT assignment incorrect, and/or file destination not valid.

3. BAUD RATE mismatch.

4. Faulty I/O Cable PN 16492-01.

5. Faulty Computer.

6. Faulty G-857 console.

Check to make sure that the G-857 is not in Legacy Mode:

To check if Legacy Mode is enabled press:

AUTO-OUTPUT

To turn it off press:

AUTO-OUTPUT-CLEAR

To Turn on:

AUTO-OUTPUT-ENTER

If Legacy Mode was on then the recorded data recorded needs to be downloaded as a G-856:
