Review on Standard Horizon MH-73A4B Small Black Speaker/Microphone: Compact and Powerful Communication Device by Scott Goff

Excellent waterproof microphone with speaker! I paired it with a Yaesu FT-270R. Reception and transmission of sound is noticeably better than with standard components! The sound level is very clear, no distortion and LOUD. Especially if you cut it near the head. I was impressed by the signal from the local repeater. The microphone is very comfortable and durable in my hand. You can tell it's built to last. I plan to use the mic for hiking, spelunking, and geocaching. Worth every penny.
