No one wants to use a satellite distress beacon or other electronic emergency communications device, but prudent seamanship dictates having one or more on board in the event of a worst-case scenario. Here are three types to consider.

Sat Messenger: SpotX with Bluetooth

The Uplink: With a SpotX two-way satellite messenger, a keyboard lets you transmit an international SOS via the GEOS satellite network, along with your position using built-in GPS. Private monitoring bases coordinate a response. You can also send and receive messages with a Bluetooth connection to your cellphone. Operational battery life is 240 hours for this compact device.

The Disconnect: Unlike an EPIRB or PLB, SpotX requires a subscription plan, starting at $11.95 per month.


Price: $249.96 (plus service plan);

EPIRB: ACR GlobalFix V4

The Uplink: This EPIRB has GPS, auto water activation, a 10-year battery, 48-hour broadcast time, self-test functions, LED strobe and upright flotation. It operates on COSPAR-SARSAT and MEOSAR satellite networks for global coverage with no subscription fee. The battery is user-replaceable. ACR’s optional portal sends confirmation test messages via cellphone or email.

The Disconnect: Needs to be registered for effective rescue response. Auto-release bracket is optional.


Price: $469.95

It includes a GPS, seven-year battery life, 24-hour broadcast time, LED strobe, test function and retractable antenna.

The Disconnect: Needs to be registered. The PLB must be attached to its pouch in order to float.
