Quick Answer
PLB (Personal Locator Beacon) devices are designed to send a distress signal to emergency responders, typically via satellite, when activated. However, they have limited functionality and may not provide accurate location information. Satellite messengers, on the other hand, offer more features and better location accuracy.
Choosing Between a PLB and a Satellite Messenger
When deciding between a PLB and a satellite messenger, consider the type of activity and the terrain you’ll be in. PLBs are ideal for situations where you’re in a remote area with no cell phone coverage and need to send a simple distress signal. They’re also more affordable, with prices starting at around $200-$300.
Features and Functionality
Satellite messengers, like satellite phones, offer more features and better functionality. They can send text messages, email, and even enable two-way communication. Some satellite messengers, like the DeLorme inReach, also offer GPS tracking and weather forecasts. When choosing a satellite messenger, consider the device’s battery life, data plan costs, and subscription fees. Look for devices with a battery life of at least 100 hours and a data plan that offers reasonable costs per message. For example, the DeLorme inReach offers a $14.95-per-month data plan with 200 messages.
Accuracy and Location Information
Satellite messengers often provide more accurate location information than PLBs, which rely on a single satellite signal to determine the user’s location. Satellite messengers use multiple satellite signals to calculate the user’s location, resulting in more accurate coordinates. This can be crucial in emergency situations where every minute counts. When choosing a satellite messenger, look for devices that offer location accuracy within 10-15 feet. For example, the Garmin inReach Explorer+ offers location accuracy of up to 3 meters (9.8 feet).
