Using Satellite SOS Devices
By the Safety Committee
In the past few years, emergency satellite communicators and locators have become less costly, prompting many groups to carry them as part of their standard equipment. Examples of these devices include Zoleo Messenger, Garmin InReach, Motorola Defy, ACR Resqlink, and iPhone 14 or later.
The main feature of most of these satellite devices is a big red SOS button, which promises to connect the user with local search-and-rescue professionals who can come to their aid.
Device Use
- Some satellite communicators have a single button: SOS. Press it and wait.
- Some satellite communicators allow search-and-rescue to message you back. Leave your device on, as they may ask clarifying questions about your status or location.
- Understand the capabilities of your device before leaving, make sure your subscription is active, and be sure to test it with your emergency contact, if it is a 2 way messaging device.
Drawbacks and Pitfalls
- Waiting to call for help. The sooner you realize the significance of your situation, the easier it will be for everyone involved. Most rescues can only be attempted during daylight hours with good weather.
- Pushing SOS and walking away (be sure to trigger only 1 SOS device per group). If someone is injured, the satellite communication device that was used to signal for help needs to stay with that person. It’s easier than you think to walk away with the device, as larger groups could split up after an injury.
- In rare cases, a device moving after the call is triggered can be interpreted as an accidental trigger and may not be responded to.
- If you have cellular service, a phone call will almost always be faster.
Practice your Skills
- DO NOT actually press the SOS button, but when you’re practicing crevasse rescue, companion rescue, or medical situations, consider “simulating” using your SOS device. Regularly practising a rescue scenario as part of “getting ready for your season,” including organising who “calls in” the incident, will give you confidence in your response should an emergency situation occur.
Additional Consideration for Rescue
A VHF radio may allow you to directly talk to a search-and-rescue helicopter pilot, provided you know the right frequency. This can greatly aid with a rescue, helping to pinpoint your location or to point out a suitable landing area.
