Hi, I am a metal detectorist and have just found a DJI Phantom advanced on my local beach. I was inverted on the sand and doesnt look like its been in the water long. Ive tried to recover the files from the micro sd card but it isn't visible to either my Windows machine or my MacBook pro. I was hoping the owner would have left an image file with their contact details on the card. Do I need specific software to download the files?
