Alerting Unit Approx Range Distances


PLEASE NOTE - the tracking ranges listed are taken from tests where the receiver antenna has been correctly installed at the recommended height with the AU9 correctly installed in either an SMB for divers or lifejacket, with antenna clip for normal use. The SMB gave the maximum range listed as achieved during tests, the lifejacket AU9 installation gave the lower end of the ranges listed. Wearing the AU9 around the neck will reduce the tracking/alerting ranges to below the ranges listed here in.
