Quick Answer
EPIRBs are more suitable for large watercraft or long-distance ocean passages rather than kayaking expeditions due to their relatively high cost, size, and weight, making them impractical for smaller vessels.
Choosing the Right Signaling Device
When it comes to kayaking expeditions, a Personal Locator Beacon (PLB) or a Satellite Messenger like a Garmin inReach are often more practical options. These devices are significantly smaller and lighter than EPIRBs, making them easier to carry on a kayak. They typically operate on a subscription-based service, offering real-time messaging capabilities.
Technical Considerations
In addition to size and weight, another critical factor to consider is the operating frequency of the device. PLBs, for instance, operate on 406 MHz, while EPIRBs operate on 406 MHz as well, but also on 121.5 MHz, a frequency that is being phased out by many countries. For kayaking expeditions, a PLB or Satellite Messenger with a 406 MHz frequency is sufficient.
Emergency Response Time
In the event of an emergency, response times for PLBs and Satellite Messengers are generally faster than for EPIRBs. This is because PLBs and Satellite Messengers can be activated manually, whereas EPIRBs are designed to automatically deploy from a life raft or emergency position-indicating radio beacon (EPIRB) when submerged in water. However, both PLBs and Satellite Messengers require a subscription to a rescue service to ensure a prompt response.
