Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


If things go abruptly sideways, this is the ace you want in your pocket. Activation is simple: deploy the antenna and press the ON button. The ResQLink 400 uses a 66-channel GPS to calculate your position within 100 metres. Transmitting on 406Mhz to the MEOSAR satellite constellation. The beacon also broadcasts a local signal on 121.5 MHz that searchers can pinpoint once they're in your vicinity.

No paid subscription is required. The only additional expense is replacing the battery every 5 years. If you need to use the ResQLink 400, ACR will replace it with a PLB of equal or greater value in return for the old beacon and your rescue story.

  • Broadcasts SOS to government funded satellite networks, so there is no monthly fee

  • Simple 1-button operation is easy to in the worst conditions, just release the antenna and push the on/off button
