Why Choose A PLB If I Have A GPS Device?

Question

Accepted Answer

Why a PLB is more effective in survival situations In extreme survival situations, communication is key. PLBs are specifically designed to send a distress signal to emergency response teams, which can lead to rescue efforts being initiated immediately. In contrast, GPS devices typically only provide location information to the user, which may not be received by anyone outside of the immediate area. This makes PLBs an essential tool for anyone venturing into remote or high-risk areas. For example, a PLB can send a distress signal to the US Air Force’s 18th Weather Squadron, which can then dispatch a rescue team. The 18th Weather Squadron is equipped to receive and respond to PLB signals 24/7.
The difference between PLB and GPS signals PLBs operate on a dedicated frequency (406 MHz) that is monitored by international authorities, including the International Telecommunication Union (ITU). This ensures that PLB signals can be received by emergency response teams anywhere in the world, even in areas with limited or no cellular coverage. In contrast, GPS signals operate on a different frequency (L1 and L2) that is primarily used for navigation purposes. While GPS devices can provide accurate location information, they do not have the capability to send a distress signal to emergency response teams.
The cost of not having a PLB The cost of not having a PLB can be catastrophic. In 2019, a solo hiker in Alaska went missing for several days before being rescued. The hiker had a GPS device, but it was not equipped with a PLB. The delay in rescue efforts resulted in the hiker suffering severe hypothermia and frostbite. In contrast, a PLB can send a distress signal to emergency response teams within 45 seconds of activation, which can lead to rescue efforts being initiated immediately.
