ALTAIR EXTREME is a set for demanding events and activities. The range has been increased to 500m in an optimal environment, the battery life is significantly extended and is up to 75h without recharging. Not only does the system operate on two independent channels, but in addition the two bodypacks can work independently without the base station, which means that those who perform their tasks and do not need to have the director's supervision are excluded from general communication. Of course, they can always return to it by pressing a single button.
