Any reduction in primary pressure triggers an automatic transfer to the secondary circuit while a vibrating alarm alerts the user, allowing a timely exit from the hazardous area.

A photo-sensitive diode automatically dims and brightens the heads-up display as light conditions change. The dual EBSS gives you two options for airline connections. High pressure (4500 psi).
