ACR Bivy Stick Satellite Communicator
ACR Bivy Stick Satellite Communicator — Product description
The Bivy Stick is a pocket-sized satellite communicator that keeps you connected when you're well past the last cell tower. Two-way texting, an SOS button, on-demand weather, and location sharing all run over satellite, and it pairs with your phone over Bluetooth. No annual contract, just flexible month-to-month airtime. It's a smart safety net for offshore and backcountry trips.
The Bivy Stick is a pocket-sized satellite communicator that keeps you in touch when you're way past the last cell tower. Two-way text messaging, an SOS button, on-demand weather reports, and location sharing all run over satellite. If you fish offshore, cruise remote anchorages, or paddle into water where your phone shows zero bars, this is the little safety net that earns its spot in the ditch bag.
What we like about it is how it works with the phone you already carry. It pairs over Bluetooth and uses the free companion app, so you type on a real keyboard instead of poking at a tiny device screen. Send a text to family, drop your position to the group, or fire off a one-touch check-in that says you're fine without typing a word. Messages go out over satellite, so it doesn't matter that you left cell coverage hours ago.
The part you hope you never use is the SOS. Hold the button and it sends your GPS position to a 24/7 emergency response coordination center, and you can text back and forth with them so they know exactly what's going on. That two-way piece matters. A beacon that only screams for help leaves rescuers guessing. Being able to tell them the engine's dead, two people aboard, taking on a little water changes the whole response.
Location sharing and check-ins are the everyday features you'll actually lean on. Set it to share your track so the people back home can follow your progress on a map, or tap the one-touch check-in at each stop. On a multi-day paddle or a long delivery run, those little pings keep everyone calm. Nobody's calling for a search at midnight because you went quiet for a few hours.
You also get detailed weather reports pulled down on demand, which is worth a lot when a front is building and you're deciding whether to run for the inlet or sit tight. The companion app carries world map data too, so you can see where you are and plan a route for just about any trip, whether that's driving, backpacking, climbing, hiking, biking, paddling, or skiing. It won't talk you through turns. There's no voice or directional announcement. It's a look-at-the-map tool, not a chartplotter, and that's exactly right for what it's built to do.
Because it isn't locked to the water, it pulls double duty the rest of the year. The same stick that rides in your dry bag on a summer delivery goes in the pack for a fall hunt or a backcountry ski tour. One device, one plan, covering every trip that takes you off the grid. For a lot of folks that's the whole appeal, since buying separate gear for the boat and the trail never made much sense.
Here's the thing that sells a lot of our customers: the airtime. There's no activation fee, and plans run month to month, so you're not locked into a full year of service for a device you use on weekends and a couple of big trips. Turn it on for the season and dial it back in the off months. You pay for coverage when you actually need it.
It charges over USB-C off the same cable and battery bank you already pack, and it ships with the USB-C charging cable, a carabiner, a cord, and a 1/4-20 adapter mount. So you can clip it to a PFD, lash it to a pack strap, or thread it onto a standard camera mount at the helm. The whole thing is a light portable stick you'll forget is in your bag until the moment you need it.
We'd point anyone whose trips run out of cell range and past easy help toward the Bivy Stick. Offshore anglers, single-handed cruisers, kayak campers, and backcountry crews all get the same thing out of it. A way to say you're okay, or that you need help, from almost anywhere on the planet. Keep it charged, keep an active plan on it through your season, and it's one of the cheapest pieces of insurance you'll ever carry.

Frequently asked questions
Do I need a subscription to use it?
You need an active airtime plan to send and receive satellite messages, but there's no activation fee and the plans run month to month. No annual contract, so you can turn service on for your season and dial it back in the off months.
How does the messaging work?
The Bivy Stick pairs to your phone over Bluetooth and runs through a free companion app. You type your two-way text messages on your phone's keyboard, and the stick sends and receives them over satellite even when you have no cell signal.
Does it have an SOS feature?
Yes. It has a dedicated SOS that sends your GPS position to a 24/7 emergency response coordination center, and you can text back and forth with them so they know your exact situation.
Can I get weather forecasts on it?
Yes. You can pull down detailed weather reports on demand, which is handy for deciding whether to run in or hold when conditions are changing.
Does it give turn-by-turn voice directions?
No. There's no voice or directional announcement. It carries world map data in the app so you can see your position and plan a route, but it's a look-at-the-map tool rather than a talking navigator.
How does it charge?

What comes in the box?
A USB-C charging cable, a carabiner, a cord, and a 1/4-20 adapter mount, so you can clip it to a pack or PFD or thread it onto a standard camera mount.
Can I use it for more than boating?
Yes. It's built for any trip that takes you off the grid, including vehicle travel, backpacking, climbing, hiking, biking, paddling, and skiing. One device and one plan cover the boat and the trail.
Can people follow my trip?
Yes. Location sharing lets the people back home follow your track on a map, and one-touch check-in sends a quick message that you're okay without typing anything out.
How big is it?
It's a lightweight portable stick designed to disappear in a ditch bag or a pack pocket. It clips onto gear with the included carabiner and cord so it rides along without taking up real space.
