We are at a football field and you can hear me with perfect clarity, why? because I have a Half-Mile Hailer right in front of me.  This little bad-boy is one of our most popular products and can cover any situation you may find yourself in.  From crowd control to a sports practice, this thing would be fantastic.  It covers up to 5000 square feet.  

is weather resistant and great in extreme conditions.  One of those extreme conditions included a hostage situation in Texas where the Hailer was brought in to communicate with the suspect, everyone was safe, everyone ...Half Mile Hailer helped in that situation.  It comes with a six year warranty and is capable of handing a wireless mic for ready and easy use.
