inReach Explorer+

#6 on this list

inReach Explorer+

Garmin

The Garmin inReach Explorer+ is a powerhouse for serious navigators and expedition leaders who need a full-featured handheld GPS combined with robust satellite communication. This device is ideal for users who rely heavily on detailed onboard mapping, waypoint navigation, and comprehensive trip planning directly on the unit, without constant reliance on a smartphone. It’s a larger, more traditional GPS device that also includes all the core inReach satellite messaging and SOS capabilities, making it a true all-in-one backcountry tool. The Explorer+ provides excellent global coverage through the Iridium network for two-way messaging and SOS. Its larger, color screen makes map viewing and navigation intuitive, and the physical buttons are easy to operate even with gloves on. Preloaded topo maps are a significant advantage, reducing the need to download maps to a separate smartphone. Battery life is good for a device with a color screen and GPS functions, typically lasting several days depending on tracking intervals and screen brightness. While heavier and bulkier than the Mini series, its comprehensive mapping and navigation capabilities, combined with reliable communication, justify the size for users who demand an integrated solution. For those who want the best of both worlds – advanced navigation and dependable satellite messaging – the Explorer+ remains a strong, field-proven choice.

Bivy Stick

ACR Electronics

The Bivy Stick is a compact and user-friendly satellite communicator that positions itself as an accessible entry point for adventurers. It's particularly well-suited for those who want a simple, lightweight device primarily for two-way messaging and SOS, leveraging their smartphone for the main interface. The Bivy Stick operates on the Iridium satellite network, ensuring global coverage and reliable communication in remote areas. Its minimalist design and intuitive app make it appealing for casual adventurers, hikers, and weekend warriors. Where the Bivy Stick shines is its flexible, credit-based subscription plans, which can be more economical for infrequent users. You buy credits and use them as needed for messages or tracking, rather than being locked into a fixed monthly plan. This flexibility can significantly reduce annual costs for many. The device itself is small, durable, and easy to carry. All messaging, tracking, and SOS activation are managed through the Bivy app on your smartphone, which is well-designed and straightforward to navigate. Battery life is respectable for its size, typically lasting several days with moderate use. While it lacks onboard mapping or advanced navigation features, its focus on reliable, cost-effective messaging through a simple smartphone interface makes it a strong contender for those prioritizing convenience and value.
