Quick Answer
An emergency locator transmitter (ELT) can be a reliable tool for backcountry safety, but its effectiveness depends on the device's design, battery life, and the surrounding environment.
Choosing the Right ELT
When selecting an ELT, consider the device’s battery life, which should last at least 48 hours in standby mode. Look for an ELT with a built-in GPS and a signal transmission range of at least 200 nautical miles. Some popular ELTs include the Aircast 406 and the ELT406-2.
Activating the ELT
To activate the ELT, pull the emergency handle or press the activation button. This will send a distress signal to emergency responders, including the location and altitude of the device. The signal may take a few minutes to transmit, so it’s essential to have a backup plan in case the ELT fails to activate.
Limitations of ELTs in Backcountry Safety
While ELTs can be effective in emergency situations, they are not foolproof. In dense forests or mountainous terrain, the signal may be blocked or delayed, reducing its effectiveness. Additionally, ELTs are not designed to locate individuals, only the device itself, so it’s crucial to have a personal locator beacon (PLB) or satellite phone as a backup.
