Marco Polo has an RC tracking unit that doesn't use GPS or need a payment plan to work, it has a 2 miles range, $200.00 for everything needed to track your quad. And it only transmits when you activae it by the tracker and that's when you trying to find it. All other times it's in a receiving state only up to 30 days for the RC version and 90 days for the pet version. Long story short "No interferance with control or video".
