Overview

The Garmin inReach Messenger is a compact satellite communicator for boats and remote travel where cell coverage drops out, letting you send and receive messages and trigger an interactive SOS when you need help.

It uses the Iridium satellite network for global coverage and pairs with a phone for easier typing and contact sync. The unit is rated IPX7 for water resistance and is small enough to live in a ditch bag or foul-weather jacket pocket at 3.1 in x 2.5 in x 0.9 in and about 4 oz.

Battery life depends on configuration and tracking interval, with up to 28 days (inReach Messenger) or up to 25 days (inReach Messenger Plus) in 10-minute tracking mode. Satellite messaging and SOS require an active satellite subscription.

Key features

• Two-way messaging over the Iridium satellite network when you are outside cellular range
• Interactive SOS messaging to a 24/7 emergency response coordination center
• IPX7 water-resistance for spray, rain, and brief submersion scenarios common on deck
• Compact form factor (3.1 in x 2.5 in x 0.9 in) and lightweight build (about 4 oz) for carry or stowage in safety gear
• On-device monochrome memory-in-pixel display for message confirmation and reading replies
• Tracking support with long runtimes for multi-day passages and backcountry trips
• TracBack routing support for returning along the path you came in
• inReach weather forecasts available on the device or through a paired phone

Variants

This product is offered in multiple configurations that change the type of messages you can send while beyond cellular range.

The listed options indicate whether photo and voice messaging is supported when paired with the Garmin Messenger app. Satellite subscription requirements still apply for satellite communication features.

• 010-02672-00: Photo & Voice Messaging: No. This configuration focuses on text messaging and SOS, which is often the simplest fit for a grab-and-go emergency communicator on board.
• 010-02887-00: Photo & Voice Messaging: Yes. This configuration supports sending photos and voice recordings through the paired app, which can help share context during troubleshooting or emergencies when text alone is not enough.

Installation and setup

There is no fixed mount required. Most boaters keep it in a known, easy-to-reach spot such as the nav station, cockpit bag, or ditch bag, then clip or lanyard it when moving around on deck.

Pair it with the Garmin Messenger app, complete activation, and send a few test messages before leaving the dock. For best satellite performance, use it where it has a clear view of the sky and avoid stowing it deep inside metal lockers while trying to message or track.

On-board use notes

This is a good match for coastal cruising, offshore runs, and remote fishing trips where you want a backstop to VHF and cellular service. It is also useful for small craft and crews who spend time away from the helm and still want a way to check in or call for help.
