Apparently the RC version of this product is a lot better than the Pet Tracker version.
I bought the Pet Tracker version and couldnt get it to work beyond 50 ft. range. The transceiver had the snub nose antenna. Your version has the high gain pigtail antenna and this seems to make a huge difference. Plus, with lighter weight and better battery, this is a superior tracker compared to the pet version.
I already have a Flytrex Live 2G but I may have to reconsider buying this RC version as a backup locator. Flytrex Live works well but is dependent on the bird's battery and I've had problems with reliability in fringe coverage areas, which is increasing because 2G is being phased out in the USA. Marco Polo doesnt care about cell tower coverage.
