For those times you need to communicate with someone, but a cell phone just won't do the job. You need to get a good set of walkie talkies. More advanced units are Bluetooth enabled, allowing you to continue communicating when you're hands are busy. There are even cool walkie talkie watches that let couples keep in touch in a secretive way. The best walkie talkies you can find will transmit on a scrambled frequency for extra security. Before you buy, check how far your two way radios will transmit so you'll know in advance if they will do the job you need them to do.
