I'm new to the board and the PV2+. I have had it for 2 weeks now and loving it. I have been reading about the horror stories about flyaways and decided that I needed to invest in a GPS tracker to protect my investment. I decided to try out this GPS tracker. http://www.amazon.com/Tagg-GPS-Pet-Trac ... words=tagg Cost less then $100 and you get 3 months of service for free and it cost $9.95 for each additional month of service. I attached it to a random collar I had laying around the house and have test flown it without any issues. It comes with a base station so I can pop it off of the collar and place it on the charger when I'm not flying. Overall I am happy with it.
