The main benefit is safety: Magnetic Mic helps you stay focused on the road when picking up and returning your radio microphone to its holder. It was invented by a police officer / driving safety instructor who noticed his trainees taking their eyes off the road for critical seconds when they picked up and hung up their police radio mics.
Magnetic Mic also increases flexibility for vehicle setup. You can install it in areas of the dash and console that are traditionally considered less-than-optimal for a microphone.
Today, Magnetic Mic is used by more than 55,000 law enforcement, fire, EMS and commercial vehicle drivers. Anyone who uses a radio microphone will benefit from Magnetic Mic.
