[Digital (406 MHz) Beacons] All alerts (100%) come from beacons (analog interference is ignored). Approximately 7 out of 10 false alerts are resolved by a phone or radio call, therefore, SAR resources are not wasted SAR assets are more available for actual distress Persons responsible for causing false alerts can avoid having to pay fines or paying the costs of operating SAR assets Follow-up to false activations allows continuous reductions in the number of false alerts [Analog (121.5 MHz) Beacons] 
False alerts may result in a long and fruitless search by costly SAR assets, although rescue co-ordination centres typically analyse the circumstances, considering location, movement of the source and confirmatory reports before launching an operation[citation needed] Searches for interference signals and false alerts inhibit SAR assets from being available for real searches
