FAQ
What is a PLB?
A PLB (personal locator beacon) is a small, portable device that is used to alert search and rescue authorities in the event of an emergency. When activated, a PLB sends a distress signal via satellite to the nearest search and rescue authorities.
How does a PLB work?
PLBs use the COSPAS-SARSAT satellite system to send distress signals to search and rescue authorities. When a PLB is activated, it transmits a signal that is picked up by satellites in orbit. The satellites then relay the signal to a ground station, which forwards the distress signal to the nearest search and rescue authorities.
Who should carry a PLB?
Anyone who spends time in remote or wilderness areas should consider carrying a PLB. This includes hikers, backpackers, hunters, fishermen, boaters, and pilots.
Do PLBs require a subscription?
Yes and no. PLBs do not require a subscription to operate. However, some PLBs (such as the Garmin InReach and SPOT devices) offer additional features (such as messaging and tracking) that require a subscription.
How long do PLB batteries last?
PLB battery life varies depending on the device. Some PLBs (such as the ACR ResQLink 400) have a battery life of up to 48 hours, while others (such as the SPOT Gen4) have a battery life of up to 15 days.
Can PLBs be used internationally?
Yes, PLBs can be used internationally. However, it is important to check with the manufacturer to ensure that the device is compatible with the satellite system in the country or region where it will be used.
Are PLBs waterproof?
Most PLBs are designed to be waterproof and can be submerged in water without damage. However, it is important to check the manufacturer’s specifications to ensure that the device is waterproof and to what depth.
Do PLBs have a self-test function?
Yes, most PLBs have a self-test function that allows users to confirm that the device is working properly. It is important to perform a self-test on a regular basis to ensure that the PLB is functioning correctly.
Can PLBs be re-used after they have been activated?
No, PLBs are designed for one-time use only. After a PLB has been activated, it must be replaced or re-certified by the manufacturer. This only applies to PLBs, not to two-way communication devices such as SPOT and Garmin.
Are PLBs reliable?
Yes, PLBs are highly reliable devices that have been proven to save lives in emergency situations. However, it is important to remember that PLBs are not a substitute for proper trip planning, preparation, and safety measures.
