Motorola VX-451 At-A-Glance

This tough little 2-way radio is a great value!  It is submersible (up to 3 ft for 30 minutes) and weatherproof.  There are several worker safety features, extra audio volume for noisy environments, and whisper mode for quite locations.  The Motorola VX-451 has the Channel Announce feature that clearly speaks the channel description to simplify changing channels while focused on other tasks.  It has numerous scan options (priority, dual watch, follow-me, 32 scan list, talk around).   The VX-451 twoway radio includes Voice Inversion Encryption for discreet communications, over-the-air Stun / Kill / Revive to disable a lost or stolen radio, Emergency notification, and the Lone Worker mode.   You can add the optional DVS-5 Voice Storage unit to record and store up to 120 seconds of important messages.
