ICOM’s new M73 Series handheld VHFs — a plus version and a basic model — are IPX8 submersible, transmit 6 watts of high power, and retain their predecessor’s (M72) slim design. “Last Call” voice recording and playback automatically saves an incoming call for 1 minute. The plus version comes with a built-in rewind feature that can replay those messages; it also features voice enhancements. Active noise-canceling technology reduces background noises up to 90 percent. Other features include dual-watch/tri-watch, favorite channel and tag scanning. The lithium-ion battery supports 18 hours of typical operation. The M73 Series starts at $249.99. Call 800-858-6177 or visit icomamerica.com.
