- Ease of Use
It's a simple device to use.
The ACR ResQLink 400 is a buoyant personal locator beacon that signals for rescue using GPS, a 406 MHz distress signal, and 121.5 MHz homing. It includes a strobe, runs 24+ hours, and needs no subscription.
From current evidence, the ACR ResQLink 400 is a straightforward personal locator beacon best suited for backcountry travelers who want reliable emergency signaling without a subscription. It outperforms satellite messengers in tough terrain and is lighter than its predecessor. The limited evidence set shows no negatives, but the coverage is too thin to be conclusive on long-term durability or usability.
