Our Verdicts
ACR ResQLink 400 GPS Personal Locator Beacon
The ResQLink 400 is not a chat device. It is the no-subscription rescue beacon for evacuation or flood-risk households that want one serious emergency trigger without maintaining a monthly satellite plan.
Earth Pak Original Waterproof Dry Bag 20L, Roll-Top Closure, 500D PVC, IPX5
At under $30, the Earth Pak 20L is the most cost-effective way to protect phones, documents, radios, and chargers from hurricane storm surge and driving rain. The 500D PVC and roll-top closure handle IPX5 conditions reliably; just don't expect it to survive full submersion for more than a few seconds. Buy two and seal the electronics separately.
