Garmin inReach Explorer+ Review

Overview

The Garmin inReach Explorer+ is a handheld satellite communicator that combines two-way text messaging over the Iridium network with full onboard GPS navigation, including preloaded topo maps. It’s aimed at backpackers, hunters, overlanders, and expedition leaders who want one device that handles both “can I get help” and “where exactly am I” without leaning on a phone. It’s been on the market since 2017, and while Garmin’s own Mini and Messenger lines have since eaten into its niche, the Explorer+ is still sold and still has a dedicated following among people who value onboard mapping over minimal weight.

Performance

Battery life is the headline feature, but the number depends heavily on settings. Garmin’s 100-hour figure is based on a 10-minute tracking interval. The inReach Explorer can last 100 hours at a 10-minute tracking mode, which is the default setting, and up to 75 hours at 10-minute tracking with 1-second logging, and up to 30 days at the 30-minute interval power save mode. In practice, several long-term users report a more conservative real-world number for typical trail use. Battery life is typically 4-5 days if you are careful about the tracking intervals you use, you keep the screen brightness at a low-level, you turn the device off at night, and configure the screen to automatically lock after a short interval. One rider who used the device for 14 hours a day on a motorcycle trip could get 3 days of 14 hours of riding out of the device before it drops below 20%. That’s a decent margin, but it means multi-week trips still need a plan for recharging via USB.

Tracking accuracy is tied directly to your log interval, and that’s a real trade-off. If you want a reasonably accurate distance-traveled readout, you can’t just leave the device on defaults. A one-second log interval is also necessary if you want an accurate estimate of the distance you’ve traveled — one reviewer experienced 25-50% mileage discrepancies in the Explorer+ trip computer compared to paper maps when recording tracks with the longer default 1-minute log interval, which trades better battery life for decreased accuracy. Dial in the interval for what you actually need: tighter for someone watching your dot closely, looser to stretch battery on a known route. You also need to define the send interval in which your logged track points are sent to the Garmin web site — if someone is following your route closely, you’ll want a more frequent sending interval, but if you’re following a predefined route on a trail, a less frequent interval is probably sufficient and will also extend battery life.

Navigation is the Explorer+‘s real differentiator versus the smaller Mini line. Because it has onboard topo maps rather than relying entirely on a paired phone, you get GPS routing without needing your phone alive and in hand. One long-term user summed it up well: battery life is excellent, and having the ability to check topographic maps aids with navigation where you could literally and truthfully tell someone that the destination is just “5 minutes away”. Another reviewer who put serious mileage on the device called it fantastic as a standalone GPS, saying as a GPS, the Explorer+ is fantastic, though the same review flagged wanting better support for maps, good quality maps, and an easier-to-use virtual keyboard.

Messaging works as advertised, but the interface is slow. Since there’s no touchscreen, composing anything beyond a preset message means thumbing through a button-based virtual keyboard, which is universally cited as the weak point of the UX. Reviews consistently mention the keyboard as tedious, and Garmin never fully solved this on the Explorer+ generation — it’s part of why the company eventually leaned harder into phone-paired devices for text entry. Bluetooth pairing to the Earthmate app is generally solid but not flawless; some users have reported Bluetooth pairing has also been flagged as inconsistent on certain Android devices, disrupting the Earthmate app experience.

SOS and safety features are the reason most people buy this thing, and they seem to deliver. The interactive SOS connects to a live 24/7 monitoring center rather than sending a single fire-and-forget signal. The SOS function connects you directly to the GEOS rescue monitoring center around the clock; it’s an interactive exchange, not a silent distress flare. A search-and-rescue volunteer reviewing a similar Garmin device (Mini 2) echoed the value of that two-way link, noting the 2-way communications are so helpful to the rescuers, speaking as someone in search and rescue who knows this firsthand.

Durability and water resistance hold up in the field. The IPX7 rating means it shrugs off stream crossings and downpours — IPX7 water resistance means it handles river crossings and heavy downpours without fuss. One long-term owner who’s used the device across the Appalachian Trail, John Muir Trail, and Kilimanjaro simply keeps it clipped to a shoulder strap trip after trip.

Pros & Cons

Pros

• Onboard topo maps and full GPS navigation without needing a phone
• Long battery life relative to competitors when tracking intervals are dialed in conservatively
• Interactive SOS with a live 24/7 monitoring center, not just a one-way alert
• True global Iridium coverage with no dead zones
• IPX7 water resistance and generally rugged build quality

Cons

• No touchscreen — button-only text entry is slow and one of the most consistently criticized aspects
• Heavier and bulkier (213 g) than newer Mini-class communicators
• Battery life claims are best-case; real-world use with frequent logging can cut it closer to days, not weeks
• Requires an ongoing paid subscription on top of the device cost, and plan tiers can feel restrictive for occasional users
• Garmin’s own newer devices (inReach Mini 2, Messenger Plus) have largely superseded it in weight and usability, leaving the Explorer+ feeling like a legacy product

Who Should Buy This

The Explorer+ makes sense for people who want serious onboard navigation bundled with their satellite communicator — hunters, trip leaders, overlanders, and hikers who don’t want their GPS functionality tied to a phone’s battery. If your priority is minimum pack weight and you’re comfortable running Bluetooth-paired maps through Earthmate on your phone, the inReach Mini 2 or Messenger Plus will serve you better for less bulk. But if you want a standalone device with real maps and don’t mind the extra weight, the Explorer+ still earns its keep.

Verdict

The Garmin inReach Explorer+ remains a capable, rugged two-in-one GPS and satellite communicator, and its safety net — a live, monitored SOS channel on the global Iridium network — is the main reason to own one. That said, it’s shown its age against Garmin’s newer, lighter, more phone-integrated lineup, and the clunky keyboard and 213 g weight are real costs for the mapping capability you get in return. I’d rate it a 7.5/10: still a trustworthy tool, but check out the Mini 2 or Messenger Plus before you commit if weight and interface speed matter more to you than onboard maps.
