Quick Answer
Disadvantages of using a PLB include its limited range, high cost, and potential for false alerts.
False Alerts and Interference
PLBs can be triggered by accidental activation or false signals from other devices, such as those used in the aerospace and automotive industries. This can result in unnecessary emergency responses and wastage of resources. To minimize the risk of false alerts, it’s essential to follow proper activation procedures and ensure the device is properly calibrated.
Cost and Maintenance
PLBs are relatively expensive, with costs ranging from $200 to $500 or more, depending on the type and features. Additionally, these devices require regular maintenance, including battery replacements and system checks, to ensure they remain operational. It’s crucial to budget for these expenses and plan for the potential need for repairs or replacement.
Technical Limitations
PLBs have a limited range, typically covering distances of up to 1,000 nautical miles (1,852 kilometers) or more, depending on the satellite network used. However, this range can be affected by various factors, including terrain, weather conditions, and the presence of obstructions. This means that users may not receive a signal in areas with poor coverage or during adverse conditions.
