Speak and listen without holding the GPS/Radio. This Earbud Push-to-Talk microphone lets you hear clearly even in noisy surroundings, and lets you have clear communication.
THIS ENABLES YOU TO BE MORE EFFICIENT WHILE HUNTING OR IN THE WOODS, IT ALSO KEEPS ALL THE COMMUNICATION BEEPS IN YOUR EAR AND NOT THE ANIMALS AND THATS VERY IMPORTANT WHILE STALKING GAME AND HUNTING.
If you are using the Garmin radio you must have this earbud. I geared up for a Colorado elk hunt this fall with the Garmin GPS and radio combination, purchasing the ear bud to go with it. You don't want the radio making any noise when that big bull shows up. It did the job. Funny story, unknowingly the ear bud fell to the ground at the campsite when I got out of the truck. The truck later drove over it. My hunting buddy found it later that day and it still worked!
