After losing my Air 2 with a failed Find My Drone update, I decided to get a Marco Polo. Having just received it, I took it for a test this evening and I'm not sure my unit is working right. We live in the desert in SW Utah. I went walking out into a forest of Juniper trees... about 15 feet tall with open space between each other. I set the transmitter down... then walked out about 1/2 mile. When I turned on the tracker the signal was quite low.... 8-10% and the unit did not show a direction arrow. I started walking toward the transmitter and the arrow showed up a bit more but often pointed off to the side from where the transmitter was located. The arrow was not on the screen so much that I doubt that I would know where to go if this was my lost drone. Also, the Marco Polo is supposed to work to a distance of 2 miles. Is this the way your Marco Polo operates? Or do I have a lemon?
