The Avon-ISI, Viking Seven SCBA, utilizes a new proprietary wireless communications network that reduces power consumption by more than 50% less power than a Bluetooth network and eliminates any cross interference from any other SCBA. The new wireless network is ideally suited for the SCBA because of its flexibility for upgrades. With the new SCBA wireless network software can be updated and reprogrammed, using only a laptop computer and a wireless card. Thus, the new network will save you time and money.
