When cell phone service is unavailable, smart survivalists need to be prepared with alternate forms of communication. The Uniden Atlantis 155 is a Two-Way VHF Floating Marine Radio. Uniden radios have maintained their reputation for quality, hand-held rugged radios that produce clear sound and feature all NOAA weather channels. They also use all USA, International, and Canadian marine channels. A warning tone will signal when a hazard is issued. Channels 16 and 19 are simultaneously monitored for a signal while allowing you to the selected channel. Both emergency channels can be scanned regularly within normal scanning cycles. The Weather Alert Watch mode will mute the radio while monitoring a weather channel preset. If there are broadcasts on that channel, it will sound an alarm. The Atlantis includes a brilliant backlit LCD channel display to use with ease at night. This radio is perfect in nearly every weather condition. It is designed to float and meets JIS8 Submersible waterproof standards. When communication emergencies arise, the Uniden Atlantis Two-Way Marine Radio will be your best friend.
