Garmin GPSMAP vs Montana: Comparing Garmin’s Top Handheld GPS Devices
Posted on October 13, 2025 by Guy Arnold
Garmin has built a reputation for designing rugged, reliable navigation tools trusted by outdoor professionals, adventurers, and search teams worldwide. Among their most capable devices are two families that dominate the handheld GPS market: GPSMAP and Montana.
While both lines share Garmin’s precision mapping, satellite navigation, and robust construction, they cater to slightly different types of users. This guide explores each range and compares the leading models available through Outfitter Satellite, including side-by-side specification tables to help you decide which is best for your next expedition.
The Garmin GPSMAP Series
The GPSMAP range represents Garmin’s classic handheld design; compact, tactile, and built for field use where portability and durability matter most. The current lineup includes:
- GPSMAP 65 / 65s
- GPSMAP 67 / 67i
- GPSMAP H1 / H1i Plus
These units retain the familiar button-based interface that works reliably with gloves, rain, and cold conditions, ideal for hikers, surveyors, and backcountry navigators.
GPSMAP Key Features
- Multi-band GNSS reception for improved accuracy under canopy or near cliffs
- High-sensitivity quad-helix antenna
- Preloaded TopoActive mapping (region-specific)
- Long battery life with USB-C rechargeable or AA options (depending on model)
- “i” variants include Iridium satellite communication for two-way messaging and SOS via Garmin inReach

Which Garmin Handheld is Right for You?
Choosing between the GPSMAP and Montana families depends on how you navigate and communicate.
- Choose the GPSMAP if you want a compact, button-operated handheld built for precision and endurance. It’s the best option for climbers, foresters, and anyone travelling light.
- Choose the Montana if you prefer a large touchscreen with automotive-grade navigation, mapping detail, and versatile mounting. Perfect for off-road or vehicle-based expeditions.
- Opt for an “i” model (such as the GPSMAP 67i or Montana 710i) if you need Iridium satellite messaging and SOS through Garmin inReach, especially valuable in areas without cell coverage.
Garmin continues to set the standard for handheld navigation and safety. Whether you need a pocket-sized GPS for backcountry travel or a full-featured mapping system with two-way satellite communication, Outfitter Satellite offers the complete lineup of GPSMAP and Montana devices with service and accessories to match.
