The ACR Bivy Stick offers global satellite communication for outdoor adventures, serving as a reliable hardware device to keep you connected off the grid.
However, it heavily relies on the Bivy Stick app, which has some drawbacks. Both the Android and iPhone apps can drain phone batteries quickly and may freeze in areas with no cell service. To mitigate this, only allow the app to use GPS when necessary. Additionally, it requires a clear view of the open sky for the best signal strength.
On the positive side, it offers two-way messaging, emergency SOS, group tracking, and offline maps. During our testing, we found that some initial messages ended up in the recipient’s spam folder, but this can be easily resolved on your computer.
If your primary purpose is to have a device for emergencies and simple check-ins, the ACR Bivy Stick is a decent ultralight choice. However, it’s important to rely on the device for check-ins rather than the app, as the app’s location accuracy can be inconsistent. In conclusion, practice using the device to make the most of it.

A satellite messenger is an essential piece of gear for backcountry adventures like backpacking, mountaineering, and wilderness expeditions where you venture beyond cell phone reception. Satellite messengers allow you to communicate from remote locations by sending SOS alerts and text messages via satellite networks. Unlike cell phones that rely on towers, satellite messengers work virtually anywhere through communication with orbiting satellites. This allows you to call for help from anywhere in an emergency and provides peace of mind when you are far off the grid. Satellite messengers are compact, durable devices that can be a lifesaver for backcountry travelers exploring mountainous terrain or deep wilderness areas.
While satellite messengers are primarily emergency communication devices, some models do provide basic navigational capabilities. Many messengers allow you to share your GPS coordinates so contacts can view your location. Some models have navigation features like locating coordinates, checking compass headings, tracking routes, and mapping waypoints. However, satellite messengers have limited screens and maps compared to dedicated GPS devices. For full backcountry navigation capabilities with topographic maps, route planning tools and more advanced features, you will likely want to pair your messenger with a standalone GPS unit or navigation app.
Satellite messenger prices range from $150 to $500 for the device alone, depending on the features. Most messengers also require an annual or monthly subscription, costing between $12 and $45 per month for messaging. Budget-friendly options like inReach and Somewear offer basic two-way messaging and SOS with lower subscription fees. Mid-range models have added navigational features and improved displays, with moderate subscription costs. Top-tier messengers boast extensive coverage, rugged builds, extra power options, and advanced navigation tools but come with higher subscription fees. While budget options work, investing in a more full-featured model can offer better reliability and capabilities for high-risk wilderness adventures. Your needs and budget will determine the right balance of affordability and functionality in a satellite device and subscription.
