I found child locators that are close to what I'm looking for, but they only work one way, ie mom can use it to findchild, but child cant use it to find mom. Also, these work at too small of a distance (600 feet) to be useful. Is there anything like this that works in a scope of a mile or two? Like maybe one of those high power walkie talkies? Preferably something that doesnt use GPS, because my searches for personal GPS show that there doesnt seem to be a way to tune a GPS to look for other GPS, it just tells you where you are but not your friends location.
