I received a Soren "Luggage LocatorPro" as a gift to help find my luggage at the airport. It works great from up to 60-feet away, chirping and flashing when the key chain remote is pushed. Another neat thing about it is that the receiver chirps longer the farther one is away from it.
I do much camping and now use the locator to find my tent or anything else that I place the receiver at. It is also made to be weather resistant. The receiver uses a single AA battery. I have gotten the equivalent of 4-weeks continuous use on a battery. The key chain button uses coin-size batteries. I have not replaced them yet. Amazon.com lists the locator at about $25. - Gil Laster, Charlotte, NC [Non-text portions of this message have been removed]
